Twilight star Robert Pattinson will be watching Prince William marry Kate Middleton on 29 April

Robert Pattinson reckons marrying Prince William is going to make life quite a challenge for Kate Middleton – because she’ll have to be on her best behaviour all the time.

‘It’s going to be hard because people will lay responsibilities on her that seem totally irrelevant,’ he says.

‘You can’t mess up, either. As an actor, you can kind of mess up – but not if you’re a Royal.’

The Twilight star, 24, is a fan of the British monarchy – especially the bolshy eccentrics.

‘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!”‘ Robert tells the Radio Times.

‘That’s one of the coolest things about England, I think, that we still have this crazy old system in place.

‘I’ll definitely be watching the royal wedding. I mean, they’re absolutely obsessed with it in America, it’s insane … but I guess it’s kind of a big deal. Actually, I think it’s really sort of fascinating.’
