Russell Brand Rocks The Mic

By MICHELE YEO

Russell Brand has been a rock star in the comedy world for several years, so it's not a huge surprise that he was cast in the film adaptation of the smash Broadway musical, Rock of Ages. But even though he's no stranger to commanding a stage with a mic in his hand, Russell says there are some differences between being a rock star and a stand-up comic.

"I'd say that rock stars are inherently more sexy," he explains to ET Canada's Matte Babel. "They're cool because they come out there and they're like 'yeah, we're gonna get in your knickers,' and I might say something like that to people. But it's a joke - though I do actually do it... it's just a joke when I'm saying it."

In Rock of Ages we get to see a different side of the funnyman - his musical side - when he belts out a few '80s rock classics in the film, including Starship's We Built This City and Joan Jett's I Love Rock and Roll.

The actor wasn't overly nervous about showing off his vocal chops for the first time: "It's quite relaxing actually and Alec Baldwin was there too."

Russell and Alec share a lip-lock in the movie and it seems to have left its mark on the British comedian. "I love Alec Baldwin so much," he admits. But don't call his affection for Alec a "man crush." "I love him, but I don't want to like, do a drawing of him on my pencil case," he adds. "Or like imagine what it would be like if I was in bed with him. Oh now I've imagined it... it was alright!"

Something else Russell has some love for - Canada: "I love that place. Everyone's really cool there. Except for when a hockey game goes wrong... everybody wants to have a fight!"
