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.
