The 24-year-old actor feels that Middleton, who is all set to tie the knot with Prince William on April 29, should prepare herself for "responsibilities", Femalefirst reported.
"It's going to be hard for her because people will lay responsibilities on her that seem totally irrelevant. You can't mess up either," he said.
The 'Water for Elephants' actor is looking forward to watch the royal wedding on television.
"I'll definitely be watching the royal wedding. I mean, they're absolutely obsessed with it.
It's insane but I guess it's kind of a big deal. Actually, I think it's really sort of fascinating," Pattinson said.
