Kate on Kate! Kate Hudson has been living in London with fiance (and Brit) Matt Bellamy, their two-year-old son Bingham, and Ryder, her 9-year-old son with ex Chris Robinson — and while the Oscar-nominated actress, 34, is slightly familiar with the rigors of a public pregnancy, nothing compares to the birth of Kate Middleton's royal baby Prince George.

"It was insane, actually," the Reluctant Fundamentalist star told Jay Leno on The Tonight Show Wednesday of royal baby fever in the British capital. "You can't help but follow it since it's on every news channel like that's all you saw …that was the longest labor on news. It literally was full coverage."

The Hollywood-raised star (Goldie Hawn is her mom, and Kurt Russell is her de-facto stepfather) hasn't met the Duchess of Cambridge or her husband Prince William — but there's an unexpected connection! "Prince William and Prince Harry actually stayed at our house in Colorado when they were kids.," Hudson explained. "I remember we were all in LA and they were staying with their mom [Princess Diana] at the time…and we get this phone call at the house."

She continued of the royal-encounter-by-phone: "And the phone rang, my dad [Kurt Russell] answers it, gets on the phone…sure enough, I think it was Prince William calling my dad to ask if he could use the ATVs, the four wheeler things." After Russell, now 62, acquiesced, "[he] said, 'now that's a really well raised boy.' That was pretty cool…that's as close as I got!"

Hudson can also perhaps relate to the new mom Middleton, 31: Many royal watchers had expected the Duchess to give birth to a girl when the arrival was, in fact, a boy. The star had a similar experience while pregnant with Bingham over two years ago.

"There was not a question in my mind that it was a girl… because it was completely different, totally different pregnancy — I carried different, he felt different [than Ryder], it was just a girl," she said. "I felt like this was a she." Muse frontman Bellamy, 35 — and older brother Ryder — both knew otherwise. "He knew…the whole time, Ryder knew the whole time it was a boy, and I just ignored them."
