"TLC are truly music pioneers and this movie is a fantastic way to expand our scripted push by combining our audience's passion for music with their love of story," Jeff Olde, VH1′s EVP Original Programming and Production, said in a statement (via Deadline.com).
The movie is set to begin filming next month in Atlanta. T-Boz and Chilli both serve as consultants and executive producers on the film.
