But Perry fears the global interest in the highly-publicised wedding will be difficult for the royal couple to cope with. “I think the whole world is going to be watching that one. The whole world is going to be tuning in," Contactmusic quoted her as telling The Sun.
“I think it's just one of those moments that you don't want to miss. I find the whole royalty system very interesting because we don't have it in the States. One of my favourite subjects has always been history, and Russell has been very helpful filling me in with the history of the English," she added.
“Going by history, the interest in Kate and William's relationship is probably a hundred times what we get. I don't know them first-hand, but from an outsider's perspective it looks like it's going to be really fun for them but a lot of hard work at the same time," said Perry.
