Alec Baldwin is set to play a homosexual stoner in the new movie “Rock Of Ages.” He was talking to “Extra” about how he almost FREAKED out when he had to kiss Russell Brand! And it’s not because he’s kissing a guy…

It’s because it’s Russell! Before they kissed, apparently Russell told him that when they kissed, it would be like they were both kissing all of the other person’s former kissing partners. And Alec panicked because of how many women Russell has been with. hahaha

Alec Baldwin’s about to marry his fiancée Hilaria Thomas, but that’s not going to stop him from gushing about locking lips with Russell Brand.

“Before we kissed, Russell said, ‘Alec, think about it. When you and I kiss in this scene, we’ll each be kissing all the other people we’ve ever kissed.’ … I started to get a bit tense, and (Brand) said, ‘Alec, that could be hundreds of thousands of people.’ It really gave me pause. It’s clear that Russell has had a very full life. I thought, ‘My god, there are women strewn around hotel rooms around the globe who I now have a bond with.”’

Brand, who recently divorced from “Part Of Me” singer Katy Perry, complimented Alec as well. “[The kiss] is sexy because Alec is a sexy man,” the 37-year-old British comedian said earlier this month. “I’d do it again if there was a sequel – or even if there wasn’t.”
