Knight, Winans Go "Bad" for Tyler

Even though Tyler Perry's latest cinematic endeavor hasn't been billed as a musical, he's certainly got enough talent in the flick to make it one. According to The Hollywood Reporter, both Gladys Knight and Marvin Winans are joining the cast of I Can Do Bad All By Myself. They join the already announced Mary J. Blige in the film.

Ms. Knight will play Wilma, a neighborhood mother who also sings at Madea's church. No word yet on whether Winans will stretch his acting chops. So far, he's just down to sing. I Can Do Bad All By Myself hits theaters in September.
