Robert Pattinson has denied reports he is secretly dating his Twilight co-star Kristen Stewart, insisting he is still completely single.

The actor was photographed getting close to Stewart during a Kings of Leon concert in Vancouver, Canada on Saturday during a break from pre-production on their third vampire film, The Twilight Saga: Eclipse.

However, Pattinson remains adamant he is a bachelor - and he even wonders why he doesn't have a girlfriend.

He says, "I don't have a girlfriend. I don't know why. You always think you're going to get more girls after you've made a movie and it never happens. You sit there and you're like 'I'm a big movie star and I want to go out with some models' but I don't know why that doesn't happen."

"It's especially different in L.A. Most of the women there are actresses and by default that makes them a little bit nuts - not that that's a bad thing. But I don't really have a type. Whenever I get asked who my favorite celebrity crush is, I have no idea."
