Robert Pattinson is keen to collaborate with hip-hop star Eminem.

The 'Twilight' actor - who is also an aspiring musician - revealed he used to be "obsessed" with the 'Not Afraid' hitmaker, and would love to be given the opportunity to perform alongside his idol.

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

However, while the 24-year-old hunk fancied his chances as a rapper, he confessed he used to steal his rhymes from other people because he wasn't "ghetto" enough to come up with his own lyrics.

Robert added 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!"
