Robert Pattinson Is Tom Cruise's 'Dirty Dog' In New MTV Movie Awards Promo

We're going to go right out there and blame it on the long weekend for being a little late to post the newest 2010 MTV Movie Awards promo, but it's so freaking funny, that we figured most of you out there should see it again in order to get your week started right.

So press play below and check out Robert Pattinson getting grooming tips from movie exec Les Grossman (ahem TOM CRUISE!), who we last saw dancing to Flo Rida's "Low" in "Tropic Thunder." When asked how he plans to prepare for his big night at the Movie Awards, RPattz says, "Maybe [I'll] get a suit, have a shave. Maybe [I'll] wash my hair." Find out what Les thought of his glam plan by watching the full video. That's our dirty dog, playa!

Don't miss the 2010 MTV Movie Awards, airing live from Los Angeles on Sunday, June 6, at 9 p.m. ET/PT.
