Maria's brush with royalty!

It's always a star-studded affair at Wet Republic at MGM Grand in Las Vegas, but on Saturday, things were feeling especially royal. As it turns out, Prince Harry partied poolside at the swanky venue, which also hosted Jennifer Lopez and Maria Menounos.

At the Do Something! Awards in Santa Monica on Sunday, Menounos dished to Us Weekly on almost bumping into the third heir to England's throne.

"He walked by us," the former Dancing with the Stars contestant told Us. "I was with J.Lo in her cabana and he was a couple cabanas down. He seemed like he was just having a good time!"

The last time Prince William's single brother, 27, hit Sin City was last November, when he spent 12 weeks in the western U.S. for an Apache helicopter training course.

While Stateside, he trekked through the Arizona desert on a black Harley-Davidson Softail Classic motorcycle, received VIP treatment while touring Hollywood's Universal Studios and shopped at Walmart.
