Prepare for a Hilton wedding! No, no — semi-reformed wild child Paris Hilton isn’t getting hitched. It’s her little sister, Nicky! The 30-year-old hotel heiress said “yes” to longtime beau James Rothschild when he popped the big question this weekend, reports Us Weekly.

James, heir to a famous European banking family, got down on one knee while the couple were taking in scenic Lake Como, Italy. A source tells Us the two took a boat ride out to the middle of George Clooney’s favorite haunt where James got down on one knee and proposed. “It was incredibly romantic and beautiful,” the insider says. “They are both really excited and incredibly happy.”

The two have been dating since 2011 after they met at a wedding. Now it’s time for their own! But before the planning kicks in, they’re still over in Europe on what Us has styled an “engagement-moon.”

“They are going on a road trip now throughout Europe and celebrating,” the Us source says. Somehow we think our idea of a road trip is a touch different from a hotel heiress and banking heir’s idea of a road trip. See for yourself in the fun snapshots Nicky’s posting from the journey! Interestingly enough, we’re not seeing a ring...

Congratulations to the couple! We can hardly wait for the big day!
