Zach Galifianakis does have a way with (nasty) words and, despite what one may think, he’s not this defensive because it’s all part of an act. He’s quite the “reluctant superstar,” as Rolling Stone describes him after an interview for the cover story in its latest issue.

Sitting down with the magazine to talk about his latest hit film, “The Hangover 2,” and how hard he’s worked (and the many times he got fired) to get to where he’s now, Galifianakis also shows why he’ll never be comfortable as an A-lister.

First of all, he hates all the attention, he says. Secondly, he doesn’t have the people skills needed to be in other A-listers’ graces, which is also pretty obvious from the things he says about them.

“I saw that Ke$ha woman the other day,” he recalls. She had e-mailed him before that, asking him out for a drink to talk. He didn’t reply, but he ran into her by accident at a bar.

“She was sitting by herself, and I walked up to her and said, ‘Listen, I got your e-mail. Your music is really bad! I don’t know who listens to it, but I imagine it’s, like, six-year-olds – and it’s a bad message’,” Zach says.

It’s not just Ke$ha that he’s managed to offend thus far and, apparently, without even trying too hard.

After the success of the first “Hangover” film, the funnyman was approached by Nike for an endorsement deal, one that would have probably put a lot of money into his banking account.

He blew the chance for a collaboration when he asked if the company still had their shoes and apparel made by seven-year-olds. He never got a call back after that.

Galifianakis also had a chance to work with Sean Penn on “Into the Blue” but, when Penn called, he told him that he had a previous engagement at Arby’s, and asked him “send my Jews the script.”

The point of the matter is, Zach says, he doesn’t know what to do with all this fame and he certainly doesn’t know how to be funny while also being politically correct.

The “Hangover” films ruined his life, he states – and there’s already talk for a third, which he confirms.

“I’m terrible about people wanting to take pictures with me. I’m a giant baby about it. They treat you like a cartoon. There’s nothing you can do except make light of it. That’s if I’m in the mood. Sometimes I get superbummed,” he tells Rolling Stone.
