Mary J. Blige, rock goddess?

"Queen of hip-hop soul" Mary J. Blige belts out some rock classics in her new movie musical, "Rock of Ages," and it may have inspired her to do the same in real life.

In an interview with CNN, director Adam Shankman joked that he cast Blige as gentleman's club owner Justice Charlier because he "wanted a daily Mary J. Blige concert, and I got it."

Shankman added that he'd like to hear her do an entire rock album, to which Blige responded, "after this, why wouldn't I?"

After all, "Rock of Ages" isn't her first time crossing over into rock music. She recorded a version of U2's "One" with the band for her 2005 CD, "The Breakthrough."

And in 2010, she and an all-star backing band - including "American Idol's" Randy Jackson - recorded a cover of Led Zepplin's classic, "Stairway to Heaven."

Take a listen, and tell us in the comments what rock songs you think she should take on next.
