OURBIRTHDAY Baby bio introduces fans to one of the young performers behind INNIT Entertainment’s new girl group, OURBIRTHDAY. Born Xie Jia-Xuan (謝佳軒) on February 10, 2009, Baby is a Taiwanese K-pop singer and dancer from Kaohsiung. Before becoming an official OURBIRTHDAY member, she reportedly gained experience as a child model, participated in the U.SSO Girl project, and trained under Source Music.
Baby’s journey is particularly interesting because her K-pop career did not begin with her official debut. She spent years developing performance experience before joining INNIT Entertainment and becoming part of the group’s seven-member lineup. In July 2026, she was introduced through the pre-debut track “HUNGRY (Side A)”, followed by OURBIRTHDAY’s official debut in August 2026.

Who Is Baby From OURBIRTHDAY?
Baby is a Taiwanese member of OURBIRTHDAY, a girl group managed by INNIT Entertainment, a JYP Entertainment subsidiary. Her birth name is Xie Jia-Xuan, and she was born in Kaohsiung, Taiwan, on February 10, 2009.
She entered the entertainment industry at a young age and reportedly worked as a child model before pursuing a more formal K-pop training path. Her pre-debut history includes a connection with the U.SSO Girl project and training at Source Music.
These experiences helped shape the performance background that she later brought to OURBIRTHDAY.
Baby is especially associated with dance. Current profile information lists her as the group’s main dancer, while fan-profile sources also highlight her ability to learn choreography quickly and perform different dance styles.
Her official OURBIRTHDAY journey began publicly in July 2026 with “HUNGRY (Side A)”, a pre-debut release featuring Baby, Cho Hyejin and Achiraya. The full group subsequently debuted on August 19, 2026.

OURBIRTHDAY Baby Net Worth
Baby’s individual net worth has not been publicly verified in 2026.
There is currently no reliable financial documentation establishing her personal savings, property holdings, investment portfolio, endorsement income, contract value or annual salary. For that reason, assigning a specific dollar amount to Baby’s net worth would be speculative.
This is particularly important because Baby is a newly debuted idol. Even when a K-pop group generates album sales, streaming revenue, merchandise income or advertising opportunities, those figures cannot automatically be treated as the personal wealth of one member.
How Could Baby Earn Money?
As her career develops, Baby’s potential income sources may include:
- Music and recording-related income
- Performance compensation
- Concert and fan-event earnings
- Merchandise-related revenue
- Brand endorsements
- Advertising campaigns
- Fashion and beauty collaborations
- Digital content
- Social-media promotions
- Future modeling opportunities
- Royalties, if applicable
However, these should be considered potential revenue channels rather than confirmed personal earnings.
A responsible OURBIRTHDAY Baby bio should distinguish between the group’s commercial activity and Baby’s personal finances. Her future income could become easier to assess if INNIT Entertainment or reliable financial reporting discloses contract, endorsement or royalty information.
Early Life and Education
Baby was born in Kaohsiung, Taiwan, on February 10, 2009. Her birth name is Xie Jia-Xuan, although English-language sources may use the spelling Hsieh Jia-Xuan.
She developed an interest in K-pop from a young age and eventually entered the entertainment industry. Her early modeling experience gave her exposure to professional photography, styling and performance environments.
Baby has also been associated with the U.SSO Girl project connected with Kids Planet. Although that project did not ultimately become a lasting idol group, the experience formed part of Baby’s early entertainment background.
Later, she reportedly became a trainee at Source Music, giving her additional experience within the Korean idol-training system.
Public information about her regular school education is limited. Therefore, specific claims about schools, academic qualifications or private educational history should not be treated as confirmed unless supported by a reliable first-party source.
Baby’s Stage Name and Real Name
One of the more interesting parts of Baby’s biography is the origin of her stage name.
Her birth name is Xie Jia-Xuan, and she has reportedly used the nickname Jia, taken from the first part of Jia-Xuan.
The name “Baby” also has a childhood connection. Profile sources report that her mother called her Baby because she looked like a baby when she was young.
During her earlier modeling career, she reportedly used Angela Baby, a name associated with Chinese actress Yang Ying, professionally known as Angelababy. She later adopted the shorter name Baby for her idol activities.
The evolution from Angela Baby to Baby therefore reflects the transition from her early modeling identity to her current K-pop career.
Baby’s Pre-Debut Career
Child Modeling
Baby’s first exposure to entertainment reportedly came through child modeling.
Working as a child model helped her become familiar with cameras and professional production environments before she entered the K-pop trainee system.
This early experience is significant because it means Baby was already familiar with public-facing entertainment work before becoming an idol.
U.SSO Girl
Baby was also connected to U.SSO Girl, a project associated with Kids Planet.
The project was intended to introduce young performers, and Baby’s involvement placed her among a generation of entertainers who began their careers at a very young age.
Her U.SSO-related period also reportedly helped her form a friendship with Na Haeun, who later became associated with the girl group UNCHILD.
Source Music Training
Another important step in Baby’s pre-debut history was her time as a Source Music trainee.
Source Music is part of the broader HYBE entertainment ecosystem and is known for developing K-pop artists. Baby’s reported training there demonstrates that her path to OURBIRTHDAY included experience with established Korean entertainment infrastructure.
Her training likely contributed to her dance, performance and stage-development skills.
Baby Joins INNIT Entertainment
Baby eventually became a trainee under INNIT Entertainment, the JYP Entertainment subsidiary behind OURBIRTHDAY.
Her move to INNIT marked another stage in her development as an idol. Instead of remaining associated with her earlier modeling and trainee experiences, she became part of a new girl-group project.
OURBIRTHDAY was positioned as one of INNIT Entertainment’s major new artist projects, with the company gradually revealing the members and their music before the official debut.
For Baby, this meant transitioning from trainee status to an active recording and performing artist.
Baby’s OURBIRTHDAY Debut Journey
“HUNGRY (Side A)”
Baby was introduced publicly as part of OURBIRTHDAY’s pre-debut rollout with “HUNGRY (Side A)”, released on July 22, 2026.
The track featured three members: Baby, Cho Hyejin and Achiraya.
This release was important because it gave audiences an early look at Baby’s performance identity before the complete group officially debuted.
Rather than introducing all seven members at once, the group used a staged rollout that allowed individual members and sub-units to attract attention ahead of the main debut.
Official Debut
OURBIRTHDAY officially debuted on August 19, 2026, with the single album Our Birthday.
The release included:
- “Our Birthday”
- “SQUEEZY”
- “HUNGRY (Side A)”
- “HUNGRY (Side B)”
“SQUEEZY” was presented as the title track.
The official debut transformed Baby’s status from trainee and pre-debut performer into a member of an active K-pop girl group.

Baby’s Role in OURBIRTHDAY
Baby is reported as the main dancer of OURBIRTHDAY.
Dance appears to be one of the strongest parts of her artistic profile. Her background includes years of entertainment-related experience, while profile information describes her as someone who can learn choreography quickly.
Her members have reportedly noticed her freestyle dancing ability, reinforcing the idea that dance is a major part of her contribution to the group.
As OURBIRTHDAY’s career develops, her performance skills could become an important part of her individual identity within the group.
Baby’s Personality, Hobbies and Interests
Although most public attention naturally focuses on Baby’s career, profile information also provides several details about her personality.
She reportedly enjoys photography, filming, editing, movies and cooking. She has also been associated with interests in foods such as matcha-flavored ice cream and simple dishes including cheese egg rolls and omelettes.
Baby is also described as having an energetic and playful personality.
Her MBTI is listed as INTJ, while her zodiac sign is Aquarius. Her representative color is pink, and her representative emoticon is a cherry.
These details have helped fans distinguish Baby’s personality and visual identity from the other OURBIRTHDAY members.
Baby’s Cherysha Character
Baby’s OURBIRTHDAY identity extends beyond her stage name.
Her associated WHIP! character is Cherysha, while cherries are used as an important symbolic element connected with her profile.
Her representative color is pink, and the cherry emoticon further reinforces the character’s identity.
This type of character branding gives K-pop groups another way to build individual identities for members. For Baby, Cherysha provides a recognizable visual concept that fans can associate with her.
Baby and Na Haeun
One of the most interesting connections in Baby’s biography is her friendship with Na Haeun.
The two reportedly became close through their earlier entertainment activities connected with Kids Planet and U.SSO Girl.
Na Haeun later became associated with UNCHILD, creating an unusual connection between two young performers who developed through similar early-career environments before joining different groups.
For fans following the new generation of K-pop performers, this connection adds useful context to Baby’s pre-debut story.
Major Career Achievements
Baby’s career is still developing, but several milestones already stand out.
Early Entertainment Experience
She reportedly entered modeling and entertainment activities while still young.
U.SSO Girl Connection
Her involvement with U.SSO Girl became an early step in her performance journey.
Source Music Training
She reportedly trained under Source Music before later joining INNIT Entertainment.
OURBIRTHDAY Member

“HUNGRY (Side A)”
She participated in OURBIRTHDAY’s July 2026 pre-debut release.
Official Debut
She officially debuted with OURBIRTHDAY in August 2026.
Main Dancer
Her profile identifies her as the group’s main dancer, giving her a defined performance role.
Assets and Lifestyle
There is currently no reliable public information confirming Baby’s personal property, vehicles, investments or luxury purchases.
Because she is still at the beginning of her professional career, online claims about her lifestyle should be approached carefully.
Her publicly documented activities mainly involve music, dance, group promotions, photography, entertainment content and other activities associated with OURBIRTHDAY.
It would be inaccurate to use the lifestyle of established K-pop stars as evidence of Baby’s personal financial situation.
Personal Life
Baby was born in Taiwan and is known publicly primarily through her professional activities.
Profile sources report that she has an older sister. However, detailed information about her family remains limited, which is appropriate given her young age and the distinction between public career information and private family matters.
There is no reliable public information indicating that Baby is married. Her public profile is currently centered on her career as an OURBIRTHDAY member.
Her friendship with Na Haeun is one of the better-documented relationships connected to her pre-debut history.
OURBIRTHDAY Baby Age and Birthday
Baby was born on February 10, 2009, making her 17 years old in 2026.
Her zodiac sign is Aquarius.
Her age is an important part of understanding her career because she entered entertainment at a young age and accumulated modeling and trainee experience before reaching her official K-pop debut.
OURBIRTHDAY Baby Height
Baby’s height is commonly listed at approximately 160.7 cm in K-pop profile sources.
Because idol profile information can sometimes change or originate from fan-maintained databases, readers should treat exact measurements as profile data rather than official medical or government documentation.
Her dance position, rather than height, is currently the more meaningful feature of her performance profile.
