Robert Pattinson wants Daniel Radcliffe to give him advice.

The 'Twilight Saga: New Moon' hunk - who plays Edward Cullen in the vampire movie franchise - admits he is still struggling to cope with fame and would like to pick p some tips from his 'Harry Potter and the Goblet of Fire' co-star.

The 23-year-old actor - who is rumoured to be dating his 'Twilight' co-star Kristen Stewart, 19 - said they both found the experience of suddenly becoming famous very surreal.

He said: "It is strange. I was having dinner with her the other day and there was some magazine cover of us and because we've been so cut off, shooting in Vancouver, it's been such an insular existence, you don't really notice what's going on.

"But we were just looking at the magazine, and I said to her, 'You realise that's actually a real magazine cover with us on it?'

"It sounds so stupid, but you are just amazed that people are actually talking about us like 'Robert and Kristen'. It's like, 'What?'"
