Channing Tatum's
stripper movie "Magic Mike" premiered last night in L.A. -- but we've got some sexy sneak peek clips from it now!

In some just-released video from the movie, we get a look at some of the crazy routines of the ab-filled flick.

Take a look at the clip above to see Channing show off his "Step Up" moves while taking off his clothes, the entire cast stripping to "It's Raining Men," Matthew McConaughey flaunting his toned stomach and Joe Manganiello doing two hot dances while dressed as a half-naked fireman.

The guys actually put some clothes on for the Los Angeles Film Festival premiere on Sunday, where Channing, Matthew, Joe, Matt Bomer, Adam Rodriguez and Alex Pettyfer all looked dapper in their suits.

Channing and Matthew were joined by their wives, Jenna DeWan and Camila Alves -- with Camila showing off her brand new wedding ring!

Also at the premiere: Costars Olivia Munn and Cody Horn.

Check out all the red carpet photos above, plus some from the Closing Night after party presented by Volkswagen.
