Actresses Keke Palmer and Drew Sidora rounds out the cast for the upcoming VH1 TLC biopic. Palmer will portray TLC member Rozanda "Chilli" Thomas, while Sidora will play Tionne "T-Boz" Watkins. As we previously reported, Lil Mama will portray Lisa "Left Eye" Lopes.

Palmer is a triple threat of sorts -- she is a actor, singer and dancer. But the 19-year-old Chicago native is mostly recognized for her acting skills. Among Palmer's film credits include the 2006 drama 'Akeelah and the Bee' and the 2012 musical comedy 'Joyful Noise' starring opposite Queen Latifah and Dolly Parton.

For Palmer, playing Chilli in a movie is her dream role. "I am a true fan," she tells VIBE of the project. "I love these ladies and I always want to be proud of my work in any role that I do."

Meanwhile, Sidora is also a fellow singer and Chicagoan whose filmography includes 'Step Up' and 'Road Hogs.'

TLC's Chilli and T-Boz will each serve as advisors and executive producers on the film, which begins production next month in Atlanta.
