Famous as a member of the all-female pop group Girlicious, she joined Chrystina Sayers, Nichole Cordova, and Tiffanie Anderson in the band after all four women won a TV talent competition called Pussycat Dolls Present: Girlicious. Mejia recorded two albums with Girlicious: Girlicious (2008) and Rebuilt (2010).
Before joining Girlicious, she trained at California's Millennium Dance Complex and graduated from Diamond Ranch High School. In addition, between 2001 and 2007, she performed with California-based bands called Cherri and Breathe.
Under the band name of the Mejia Sisters, she and her siblings Taylor and Jazzy released a 2014 iTunes single titled "Stray."
Born to a family of Cuban and Mexican heritage, she spent her childhood in Diamond Bar, California. She welcomed her first child, a daughter named Calista Estrella, in May of 2013 with her husband Johnny Roberts.
After ending her association with Girlicious, Mejia was chosen as a member of the new lineup of the affiliated band the Pussycat Dolls; however, Emmalyn Estrada ultimately took her spot in the girl group.
