And like any high profile bachelor, girls vied for his attention.
Blending into the crowd at MGM Grand’s Wet Republic, the shirtless British royal went largely unnoticed in his VIP bungalow Saturday, dressed in a red floral swim suit, sunglasses and a brimmed hat.
Most of the crowd’s attention centered a few cabanas down as Jennifer Lopez hosted the party. As Lopez walked the red carpet a mere 20 feet from his bungalow, Harry hung back, with few people noticing the unassuming royal sipping Grey Goose.
Much like his previous Vegas visit, Harry appeared chipper as he stayed in his private area, chatting with his friends and several girls. Playing with an inflatable beach ball, he jumped in an adjacent private pool, floating on the ball for a portion of the day.
At one point, several Las Vegas police officers stood near him as Harry frolicked in the water, drinking shots of vodka and cranberry juice while politely chatting with the officers and the women whom he shared the pool with.
“A few groups of women approached him throughout the day and he talked to them briefly, but he didn’t really center his attention on anyone,” an onlooker tells PEOPLE. “He definitely loved the attention, but he looked to be a gentleman with all the women.”
