15& Members Profile 2026: Bio, Age, Height & Facts
15& was a South Korean vocal duo under JYP Entertainment consisting of Jamie and Yerin Baek. The duo debuted in October 2012 with I Dream and became known for their exceptional vocals before becoming inactive in 2015.
In the landscape of K-pop, few debuts have been as anticipated as that of 15& (피프틴앤드). Formed by JYP Entertainment in 2012, this vocal duo burst onto the scene with a level of raw talent that immediately set them apart from their peers. The group’s name itself tells a story—”15″ representing the members’ age at debut, and “&” symbolizing their potential to continue growing and achieving success into the future.
Comprised of Park Jimin and Baek Yerin, 15& was not your typical K-pop girl group. Both members were already known to the public before their debut: Jimin as the winner of the first season of SBS’s “K-pop Star,” and Yerin as a child prodigy dubbed a “R&B genius” on television. Their union under JYP Entertainment created one of the most vocally powerful duos in K-pop history.
What made 15& significant was their commitment to authentic vocal performance in an industry often dominated by elaborate choreography and visual concepts. Their music—spanning R&B, pop, and soul—showcased two young women with voices far beyond their years. From their debut single “I Dream” to their full-length album “Sugar,” 15& demonstrated that they were not just teenage singers but serious artists with something meaningful to say.

Who Is 15&?
15& was a South Korean vocal duo formed by JYP Entertainment in 2012, consisting of Park Jimin (now known professionally as Jamie) and Baek Yerin (now known as Yerin Baek). The duo’s name represents the members’ age at debut—both were fifteen years old—with the ampersand symbolizing their potential for future success.
What set 15& apart from other K-pop acts was the extraordinary vocal ability of both members. Neither was a typical idol trainee; both had been recognized for their talent long before debut. Park Jimin won the first season of SBS’s “K-pop Star,” one of Korea’s most prestigious singing competitions, while Baek Yerin was discovered as a child prodigy on “Star King”.
The duo released their debut single “I Dream” on October 5, 2012, followed by “Somebody” in 2013, and their first and only studio album “Sugar” in 2014. After a four-year hiatus beginning in February 2015, the group effectively disbanded when both members’ contracts with JYP Entertainment expired in 2019.
Despite their relatively short run as a duo, 15& is remembered as one of the most vocally talented groups in K-pop history. Both members have gone on to successful solo careers—Jamie as a singer-songwriter and television host, and Yerin Baek as a critically acclaimed solo artist and lead vocalist of the band The Volunteers.
Group History
Formation and Pre-Debut
The story of 15& begins with two remarkably talented teenagers who took very different paths to JYP Entertainment.
Park Jimin’s journey to debut was nothing short of extraordinary. In 2011, she participated in the first season of SBS’s “K-pop Star,” a survival competition that would become one of Korea’s most influential talent shows. Week after week, Jimin captivated audiences and judges alike with her powerful vocals and emotional delivery. She ultimately emerged as the first-place winner of the competition.
As the winner, Jimin was given an unprecedented opportunity: she could choose to sign with any of Korea’s “Big Three” entertainment companies—YG Entertainment, SM Entertainment, or JYP Entertainment. After careful consideration, she chose JYP Entertainment on May 21, 2012, setting the stage for her debut.
Baek Yerin’s path was different but equally remarkable. When she was just ten years old, she appeared on the SBS variety show “Star King,” where she was introduced as a “R&B genius”. Her performance of Whitney Houston’s “I Have Nothing” won first place and caught the attention of industry insiders.
In 2008, at the age of eleven, Yerin auditioned for JYP Entertainment, singing Beyoncé’s “Listen”. She was accepted as a trainee at the same time as 2PM’s Wooyoung and Highlight’s Doojoon. By the time she debuted with 15&, Yerin had been a JYP trainee for four to five years.
Official Debut
On October 5, 2012, 15& officially debuted with the release of their first digital single, “I Dream“. The song was a dreamy R&B track that highlighted the duo’s smooth harmonies and emotional depth. The music video was released on YouTube on the same day.
Two days later, on October 7, 2012, 15& made their debut stage performance on SBS’s Inkigayo. The performance was a showcase of their extraordinary vocal abilities, immediately establishing them as a group to watch.
To promote their debut, 15& held “school attack” guerrilla concerts on October 12, 2012. Supported by KT Corporation’s Genie Music, the girls performed at Chungdam Middle School, Eonnam Middle School, Sungil Information High School, and Dankook University, attracting both students and local residents.
Breakthrough Success
15&’s second single, “Somebody,” was released on April 7, 2013. The music video showed the duo parodying the “K-pop Star” judge panel while reacting to staged auditions featuring cameos by Park Jin-young and some of Jimin’s fellow contestants from “K-pop Star” season 1.
The group made their comeback performance on the finale of “K-pop Star 2” on the same day. Upon its release, “Somebody” rose to the summit of music charts on Olleh, Melon, Daum, and other major Korean streaming platforms.
In April 2014, 15& released their third digital single, “Can’t Hide It“. They made their comeback performance on the “K-pop Star 3” finale, further cementing their reputation as the vocal duo associated with the nation’s most prestigious singing competition.
Major Career Milestones
Recent Activities
As of 2026, 15& is no longer active as a group. Following a four-year hiatus that began in February 2015, the group de facto disbanded upon the expiration of both members’ contracts with JYP Entertainment in 2019.
However, both members have continued to thrive in their respective solo careers:
Jamie (formerly Park Jimin) has established herself as a solo singer-songwriter under Warner Music. She was also a co-host of the popular variety show After School Club from 2014 to 2022. She continues to release music and engage with fans through her social media platforms.
Yerin Baek has become one of Korea’s most respected singer-songwriters. She has released multiple critically acclaimed EPs and albums, and is also the lead vocalist and guitarist for the indie rock band The Volunteers. She continues to be active in the music industry as of 2026.
Agency and Management
JYP Entertainment is one of South Korea’s “Big Three” entertainment companies, founded by Park Jin-young in 1997. The agency is home to some of K-pop’s most successful acts, including TWICE, Stray Kids, ITZY, and NMIX, as well as legendary groups like g.o.d, Wonder Girls, 2PM, and miss A.
15& was formed and managed by JYP Entertainment throughout their career. The agency’s decision to debut two singers rather than a traditional idol group was notable—JYP Entertainment was known for producing polished pop acts with synchronized choreography, but 15& was positioned as a vocal-focused duo.
The group’s official website was hosted at 15and.jype.com. They also maintained official social media accounts on Facebook and YouTube.
Both members’ contracts with JYP Entertainment expired in 2019, leading to the group’s de facto disbandment. Neither member renewed their contract with the agency; instead, both pursued solo careers with different labels:
- Jamie signed with Warner Music Korea
- Yerin Baek signed with Blue Vinyl and continues to release music independently
