The Best and Worst Musicians-Turned-Actors

9. Mariah Carey

Regarded by many as one of the worst films ever, Mariah Carey’s "Glitter" was the awful drama that felt more like a comedy for how bad it was. Carey's performance appeared extremely forced and unfortunately, her musical numbers were no better— it's difficult to recall even one song from the film. However, Carey should get some credit for her commendable performance in 2009's "Precious." Maybe she just needed a break from all the glitter and singing to show us some real talent.
