Nothing spells promotion for a new film as a performance on a show of this caliber

As the release of the heavily '80s-inspired musical dramedy “Rock of Ages” is drawing nearer, each of the many stars involved in it are doing their best to promote it. Mary J. Blige and Juliane Hough did so on DWTS.

The two singers were on the popular ABC dancing competition to perform and, because nothing spells excellent promotion better than offering viewers a taste of what they're promoting, they brought the house down.

Mary and Julianne sang and danced their little hearts out on Dancing With the Stars, as the video above will confirm.

If the film, which has already been panned by critics based on the trailers alone, has at least half the energy that was invested in this number, then it probably has nothing to worry about.

Check out Mary and Julianne's performance and, of course, enjoy!
