Robert Pattinson can’t understand why he isn’t dating a model.

The 23-year-old Twilight actor expected to attract more interest from the opposite sex when he shot to stardom playing vampire Edward Cullen in the first film of the hit vampire franchise. He said: “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.”

Although Robert is unhappy with his single status, he would never act on any of the female attention he does receive—because it is from people either too young or too old for him. He explained:

“Most of the girls are all pretty young so it’s just kind of funny. But then you get the ‘Twilight Mums’ who love you like mums! And you can take that too far. I mean, it could be ‘Edward breaks up Twilight family’. It’s especially different in Los Angeles. Most of the women there are actresses and by default that makes them a little bit nuts—not that that’s a bad thing.”

Robert’s first acting role was as Hogwarts tri-wizard champion Cedric Diggory in Harry Potter and the Goblet of Fire aged 18, and he was preparing to embark on a very different career path before he landed the part.

He explained to Britain’s Daily Mirror newspaper: “I was going to do the conventional thing and go to university to study International Relations. I wanted to be a politician but Harry Potter made that decision for me.”
