We've seen photos of a bikini-clad Julianne Hough from the set of the highly anticipated film, 'Rock of Ages'--and now we're getting a peek at Alec Baldwin in costume too.

Director Adam Shankman Tweeted the photo of Baldwin and costar Russell Brand on Tuesday. The '30 Rock' star is decked out with long blond hair, bandana around his neck and a killer jean vest.

Baldwin is just one of the big names starring in the big-screen adaptation. He joins Tom Cruise, Mary J. Blige, Hough and Catherine Zeta-Jones in the upcoming musical.

The 53-year-old star will play the part of Dennis Dupree, an ex-rocker who runs the Rock of Ages nightclub in order to hold onto his rock star past. Set in 1987 on the LA Sunset Strip, 'Rock of Ages' is the story of a small town girl who meets a big city rocker in an LA rock club, as they fall in love to a soundtrack of the greatest songs of the '80s.
