Early Life and Background
Baby was born Hsieh Jia-Xuan (謝佳軒) on February 10, 2009, in Kaohsiung, a major port city in southern Taiwan. She grew up in a close-knit family with her parents and an older sister born in 2006 (three years her senior).
Among friends, family, and fans who followed her pre-debut journey, she has long gone by the affectionate shortened nickname Jia.
Her distinctive stage name—and her English name, Angela Baby Hsieh—originated directly from her childhood at home.
As she shared during OURBIRTHDAY’s debut showcase, her mother is an admirer of Chinese actress Yang Ying (known professionally as Angelababy) and nicknamed her “Baby” from the time she was small because of her doll-like baby features.
Growing up in Kaohsiung, Baby worked as a child model and spent hours watching K-pop music videos, which sparked her ambition to become a performing artist in South Korea.
Combining natural rhythm with quick spatial awareness, she built an early reputation in youth dance circles before making the life-changing move abroad to pursue idol training in Seoul.
Career Highlights
Child Modeling and Early Trainee Years (Kids Planet & Source Music)
Before joining the JYP Entertainment family, Baby gained valuable pre-debut experience across multiple entertainment projects.
In Taiwan, she modeled for youth campaigns—including commercial appearances for KFC and MLB Kids—before stepping into K-pop trainee systems.
She spent time training under Kids Planet, where she was lined up as a pre-debut member of the agency’s planned girl group project U.SSO Girl (forming a lasting friendship with fellow trainee and future UNCHILD member Na Haeun).
Following the cancellation of that project, Baby entered Source Music under HYBE, honing her technical choreography and stage endurance alongside elite trainees before eventually departing the label.
Signing with INNIT Entertainment and Pre-Debut “HUNGRY (Side A)”
Baby subsequently transferred to INNIT Entertainment, an independent subsidiary label established under JYP Entertainment.
On July 16, 2026, INNIT Entertainment officially unveiled Baby as one of the first three members of its inaugural girl group, OURBIRTHDAY—JYP Entertainment’s first new girl group project in four years following NMIXX.
On July 22, 2026, Baby made her pre-debut broadcast bow as part of OURBIRTHDAY’s three-member “Side A” promotional unit alongside leader Cho Hyejin and Thai vocalist Achiraya, releasing the high-impact digital single “HUNGRY (Side A)”.
Performing on Korean music shows weeks ahead of the full group’s debut, Baby immediately stood out for her explosive isolations, expressive confidence, and commanding center presence.
August 2026–Present: Full-Group Debut with Our Birthday and Co-Choreography Credits
On August 19, 2026, all seven members of OURBIRTHDAY held their official debut showcase at Blue Square in Yongsan-gu, Seoul, releasing their first single album Our Birthday (which reached #6 on South Korea’s Circle Album Chart and sold over 123,000 copies) and its bubbly, hip-hop-infused title track “SQUEEZY”.
Beyond performing as one of OURBIRTHDAY’s two main dancers alongside Cho Hyejin, Baby also earned early creative recognition on the group’s debut release: she and Hyejin personally co-choreographed their signature dance duet section in the album track “WHIP-HOP.”
Brand Ambassadorships and Endorsements
As a newly debuted K-pop idol who officially entered the industry in August 2026, Baby has not yet announced any solo luxury or global brand ambassadorships since debuting with OURBIRTHDAY.
Prior to moving to South Korea for full-time idol training, she worked as a child model in Taiwan—appearing in campaigns for KFC (alongside Taiwanese singer Harlem Yu), MLB Kids, and youth streetwear label KIPOP.
Since August 2026, her commercial appearances have centered on full-group promotions for OURBIRTHDAY, including promotional tie-ins for the 1st Single Album Our Birthday (distributed in partnership with INNIT Entertainment and Republic Records) and Makestar fansign events.
Given her bilingual Mandarin-Korean fluency, striking visuals, and milestone status as INNIT Entertainment’s first Taiwanese artist, fashion, beauty, and Greater China lifestyle partnerships are strong future possibilities.
Personality and Public Image
Testing as an INTJ—a rare personality type among K-pop idols—Baby balances strategic focus in the practice room with an unmistakably lively, unfiltered personality offstage.
Her fellow OURBIRTHDAY members describe her as a “free spirit full of energy” whose spontaneous humor keeps the group’s atmosphere bright even during grueling debut schedules.
When the members first met her during trainee evaluations, their immediate impression was shaped by her freestyle dancing abilities and how rapidly she picks up complex choreography across different genres.
At the same time, leader Cho Hyejin affectionately nicknamed Baby “Gwangbae” because of her hilarious habit of occasionally acting and sitting like a relaxed old man behind the scenes.
Inside OURBIRTHDAY’s shared dorm—where rooms were assigned by drawing lots—Baby shares a two-person bedroom with youngest member Kilala.
Meanwhile, she and eldest member Kuk Chorok share a playful sibling rivalry, with Baby constantly trying to pull pranks on Chorok while Chorok laughs it off.
Visually represented by Pink, the cherry emoji (🍒), and her dessert avatar CHERYSHA, Baby embodies the sweet-yet-fierce duality at the heart of OURBIRTHDAY’s “WHIP-HOP” concept.
