NEW! Miley Cyrus' latest video in the Biggest Online Dance Battle Ever!

In early April, Step Up 2 The Streets director Jon M. Chu and star Adam Sevani (aka the Adam/Chu Dance Crew or ACDC) posted a clip on Youtube showing off their sleek dance moves and challenging Miley Cyrus and her BFF and back-up dancer Mandy Jiroux to the Biggest Online Dance Battle Ever. Miley and Mandy, calling themselves the M&M Cru with a U, soon posted a video response in which they proved they could bust some awesome moves too. They even got Channing Tatum, star of the original Step Up, to dance in their clip, just pushing them ahead of ACDC to be the winners in Round One (check out both clips here and see what you think).

Not content to let Miley and Mandy win the battle, however, ACDC posted another clip, this time bringing in more celebs than you see on the red carpet at an awards show. We're talking Lindsay Lohen, Chris Brown, Adam Sandler, Amanda Bynes, Brittany Snow... check it out here!

But now the M&M Cru with a U have finally responded in Round Two, and they say their new video is so good it'll end the dance battle once and for all... with Miley and Mandy as the winners, of course! Check out their new video below and tell us what you think about it on the comment board. Have M&M won the battle, or are ACDC the best no matter what?
