RP feels sorry for Kate Middleton

'It's going to be hard because people will lay responsibilities on her that seem totally irrelevant. As an actor, you can kind of mess up – but not if you're a royal. I've always liked the members of the royal family who couldn't care less what anyone thinks – the ones who go, "I'm royalty – so shut up!" That's one of the coolest things about England, that we still have this crazy old system in place.'

Pattinson recently told US TV host Jimmy Kimmel that he used to pretend he knew the royal family.

'I don't think I've ever met them. I used to tell people when I came to the States that I did. They believed me!' he said.

'Five or six years ago when I first used to come to Los Angeles there weren't many English people, now there are like a million and people still believe me.'

The 24-year-old star of the Twilight films was born in London but now spends most of his time in the US.
