Fresh from the Tyler Perry factory, the trailer for his newest film I Can Do Bad All By Myself gives us our first peek at stars Mary J. Blige and Gladys Knight. And, no surprise, they spend just as much time in the trailer singing as they do acting. Taraji P. Henson also picks up a mic (and a bottle...and Adam Rodriquez...and three kids) for what's bound to be another divisive addition to Perry's catalog of work. Perhaps the only female character who doesn't sing is the ubiquitous Madea. But we won't know for sure until the film is actually released on September 11th. [H/T: WTF]
