Actor Zac Efron looked handsome as ever while celebrating his 24th birthday with friends in London last night.

How do you say “Happy Birthday” in British?

The happily single actor, whose actually birthday was October 18th, kicked his 24th year off right by partying the night away at The Box nightclub with pals until the wee hours of the morning.

Efron, who recently signed up to star in an unnamed R-rated comedy opposite Seth Rogan, has been MIA from the Hollywood scene lately, but will hopefully reappear now that he’s slated to appear in another film.

Rogan spoke with MTV regarding why he’s surprisingly excited to be costarring with Efron in his latest project.

He was really looking to be sullied, which is why we thought it would be a good idea… I’ve met him a few times over the years and the first thing you get from him is that he knows that a guy like me would probably hate him, and he works directly to counteract that feeling, which shows an amount of self awareness that is not prevalent among many young stars these days that I’ve met at award shows recently. And I think that’s why I thought it would be really funny, he seemed like he was a really cool guy, that he’d be fun to work with and seemed that he was capable of much more than the Disney stuff we’ve seen him in.

Are tickets on sale yet?!?!?!
