Robert Pattinson's sisters used to dress him as a girl and call him Claudia when he was younger, the actor has revealed.

The heartthrob - who shot to fame off in vampire flick Twilight - admits that he wasn't always such a dapper dresser.

Rob tells the BBC, "Up until I was 12 my sisters used to dress me up as a girl and introduce me as 'Claudia'!

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

Robert has certainly come a long way since then!
