Kate, whose mum is none other than Goldie Hawn, explained how the situ came about. "Prince William and Prince Harry actually stayed at our house in Colorado when they were kids," she told Jay Leno on The Tonight Show on Wednesday.
"We were all in LA and they were staying with their mum at the time and we got this phone call at the house. Sure enough, I think it was Prince William calling my dad to ask if he could use the ATVs, the four-wheeler things."
Um, we don't know what an ATV is but that sounds SO cool! Good ol' Wills.
Though Kate said she never had the pleasure of meeting any of the royal she did say she followed the arrival of the Duke and Duchess of Cambridge's baby Prince George.
"That was insane, actually. You can't help but follow it because it was on every news channel... That's all you saw. That was the longest labour on news. It literally was full coverage."
