He may be one of Hollywood's most popular rising stars, but Robert Pattinson says his new-found fortune doesn't make much difference to him.

"I bought a really nice guitar recently, which is the only thing I've ever really spent a lot of money on. But that's the only thing," says the actor, who is currently dating co-star Kristen Stewart.

"I had my apartment in London before when I was unemployed – this tiny little place and I liked it more. You had to walk through a restaurant kitchen and up this staircase filled with trash and there's no heating. I like that.

"But now it's quite difficult. I can't live in places like that any more. The people outside, that's the only issue."
