Forget the need for bodyguards or disguises. When a prince wants to go incognito in the U.S., all he has to do is party alongside the queen of bling, Jennifer Lopez.

That was the lesson learned by Britain's Prince Harry, who went virtually unnoticed while partying at the same place as J.Lo herself this weekend, MGM Grand's Wet Republic in Las Vegas.

The 27-year-old, fun-loving royal wore baggy red Bermuda shorts, sunglasses and a wide-brimmed hat while partying in a VIP bungalow Saturday with five male and five female friends, the UK's The Sun reports.

Perhaps inspired by the hours he spent watching women's beach volleyball during the London Olympics, Harry was spotted carrying a giant inflatable beach ball and reportedly running after it in the crowd. Apparently he remained anonymous.

"Harry looked to be in his element, being able to enjoy himself without anyone outside of his group recognizing him," a source told the Sun. "They were dancing away and throwing a beach ball around, like any other young people having a good time."

Also having a good time, in a very high-profile way, was Harry's surprise paparazzi cover for the afternoon, J.Lo. The former "American Idol" host, now on tour with Enrique Iglesias, hosted the pool party just hours before her Sin City concert and happily kept the spotlight on herself, walking the red carpet and then sunning in a two-piece white midriff-baring outfit.

Lopez and her beau, Casper Smart, ate, drank and relaxed in a bungalow just a few short steps away from Prince Harry, although the trio never appeared to interact or greet each other, according to People.com.

The prince, who is the third in line to the throne, continued the fun after the sun had set, moving from the pool to the casino at the Wynn resort, where he played craps, a source told the Daily Beast.

The next day, Harry reportedly stayed at the Wynn for another pool party, this one at the luxury hotel's Encore Beach Club.

Harry last tried his luck in Vegas last November when he played several rounds of blackjack and hit the dance floor at the Wynn's Tryst nightclub. He was in the United States for a two-month helicopter training program in California and Arizona.
