Robert Pattinson's sisters used to dress him as a girl and call him "Claudia".

The "Twilight" star - who plays vampire Edward in the new movie - confessed he wasn't so "cool" when he was younger.

He said: "Up until I was 12, my sisters used to dress me up as a girl and introduce me as Claudia.

Twelve was a real turning point for me as I moved to a mixed school, and then I became cool and discovered hair gel."

Robert also revealed he finds dealing with his huge new female fan base difficult, and isn't as interesting as people may think.

The 22-year-old actor added: "If somebody asks me out on a date, I go out with them! But I never get asked.

And I never know how to ask other people. I'm not good at the whole 'dinner' thing. I'm a bit of a loner. "I'm boring. I stay home, watch TV and eat a lot of fast food. That's really exciting, isn't it?"
