Grace Belsey is a music student who was successfully coached by music teacher Jackie Walker to appear on the TV show American Diva. Brooke Allen and Rachel Burns wanted her position and were extremely hateful and crushed from being rejected, because Walker said they didn't have Grace's talent.
Grace successfully sang a rendition of the song "For Once in My Life" on the show and thanked Walker on TV, but her stardom didn't last long when Allen and Burns set Walker up for child sex abuse, getting their little brothers' DNA on sex toys and alleging Walker used them on the boys. Grace was a witness to the competition between the girls, and when Allen's mother was revealed to have used a similar con in her divorce, the conspiracy was ousted and Walker's charges were dropped. He was horrified his name was ruined while the girls received probation. It's unknown what happened to Grace's life situation and chances at a singing career. (SVU: "Dissonant Voices")
