We’re singing after last night’s party celebrating the Canadian premiere of Girl Group at RBC House! Rebel Wilson writes, directs, and stars as a fallen pop star, after being ousted from her girl group’s reunion tour and handed a community-service sentence, decides to stage a comeback by coaching a group of misfit teen girls for a major record label audition. The comedic cast includes Jennifer Coolidge, Randall Park and more greats. #RBCxTIFF Pictured: Rebel Wilson, Jennifer Coolidge, Randall Park, Loren Gray Photos: Ryan Emberley / Getty Images for RBC Venue: Petros82.to
