According to People Magazine, it was his first trip to Sin City and he started the party late Friday night at Wynn Las Vegas' Tryst Nightclub and quickly took up quarters at the VIP table. At first, Harry went relatively unnoticed as he bounced around the indoor-outdoor club, which features a large outdoor waterfall.

The fun-loving royal was later spotted jumping into the lap of one of his security guards and falling to the floor laughing when he dropped off, as People reports.

Between Grey Goose vodka tonics, Harry was seen chatting up a black-skirted blonde and dancing for a brunette. There's no word as to whether the prince landed himself a Vegas showgirl.

The intimate party wound down at 3 a.m. with the group of nine leaving the club out of a side door, with Harry quickly retreating to his room at Wynn Las Vegas.
