Gerard Butler may be known as a Hollywood bad boy, but the “The Bounty Hunter” star says he’s cooled things down — thanks to anxiety.

“I think I get laid less now than I used to, because I’m way more paranoid now. Look at f—ing Tiger Woods! I mean, I’m nowhere near as naughty as I used to be, partly because I did a lot of that when I was drinking,” he told the April issue of Men’s Journal.

“I’m not saying I’ve cut that part out. I’m certainly no angel. There’s no smoke without fire.

But here’s the thing: While they’re accusing me of that, I’ve probably been off somewhere else doing damage with someone else. I’m pretty smart like that. I know how to get away with those things.”

While the star has been linked to a number of actresses — including “The Bounty Hunter” co-star Jennifer Aniston — following his breakthrough role in “300,” he said he’s only had a pair of relationships since coming to Hollywood.

“In the last five years since coming out here, I’ve had two relationships. I’m not a big relationship guy,” he said. “One of my vices is, I’m too wrapped up in myself and not always in a good way.”
