Robert Pattinson once dreamed of being a rapper.

The British actor - who is best known for portraying vampire Edward Cullen in 'The Twilight Saga' - was "obsessed" with Eminem as a teenager and made recordings of himself performing his own composition.

He said: "You want a secret? OK, how about this - I've got a whole collection of tapes of me rapping from when I was 13! I wanted to be a rapper so there are hundreds and hundreds of tapes. They're very amusing!

"I was obsessed with Eminem when I was younger. When he first came out I was about 12 and fanatical about his 'Slim Shady' CD. I think he's a genius."

The 24-year-old star even had his own "crew" but admits his lyrics were less-than-authentic.

He explained to Top of the Pops magazine: "Most of my rhymes were stolen off other people anyway. They were all like, 'I was raised on these streets.', which was a complete farce because I was actually raised in quite a nice area of London called Barnes. Not very ghetto at all!

"I was obsessed with it all, though. I even had my own little crew - we called ourselves Big Tub and the Tappy Cats."

Robert has previously recorded tracks for the 'Twilight' soundtracks but insists he has no plans to move into music full time.

He said: "I'm a bit of an attention seeker - I love being on stage. But the thought of performing music on stage terrifies me. I'm not scared of acting though."

However, if the chance came to perform with rapper Eminem, Robert would jump at the chance.

He said: "I'd love to rap with Eminem! That would be really amazing."
