Is Robert Pattinson single or not? This is the question! A few days ago he was spotted more than friendly with his ’Twilight’ co-star Kristen Stewart, but now he claims he doesn’t have a girlfriend.

"I don't have a girlfriend. I don't know why", he declared for Britain’s Daily Mirror. So now, what could we believe?

Currently Pattinson (and Stewart) is filming ’Eclipse’, the third in the vampire series. And he pretends to be as surprised as we are because he doesn’t have a girlfriend. "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", he said. Should we believe him?
