One parties like an Olympic gold medalist and one is an actual Olympic gold medalist, so when Prince Harry and Ryan Lochte partied together in Las Vegas it was definitely not going to stay in Las Vegas.

In a 50-second video obtained by the New York Daily News, Harry, 27, and Lochte, 28, can be seen facing off Monday night in a swimming battle at a booze-filled pool party while both bachelors were living it up in Sin City.

The XS Nightclub pool at Vegas' Wynn Hotel is not quite the same venue as the Aquatics Center in London where L ochte won his five Olympic medals, but the Olympian still managed to defeat the royal in a race across the crowded pool. Lochte can be seen in the video raising his hands in victory, just as if he'd defeated former rival Michael Phelps for gold.

Lochte, who just applied to trademark his catchphrase 'Jeah,' has been testing out his newfound, post-Olympics celebrity in Vegas. On Sunday he showed off his six-pack abs in a pair of pink Speedos while posing with bikini-clad women at a pool party at the Palazzo's Azure pool and later showed his patriotism, and still his six-pack abs, in red, white and blue swim trunks while posing with one of his gold medals.

The swimmer, who turned 28 on Aug. 3 during the Olympics, has been in Vegas since Thursday hosting a belated birthday party for himself, including Olympic-themed cake, champagne and a large birthday dinner with fellow Team USA swimmers Cullen Jones and Conor Dwyer, according to People.com.

While Lochte was happily posing on the red carpet, Harry, the third in line to the British throne, was enjoying Las Vegas in a more low-key fashion, thanks to a surprising paparazzi cover, Jennifer Lopez.

The two partied nearly next door to each other at MGM Grand's Wet Republic in Las Vegas on Saturday, but the prince, according to witnesses, went unnoticed while J.Lo stole the show.

Harry, reportedly in Vegas after a charity trip to San Diego, wore baggy red Bermuda shorts, sunglasses and a wide-brimmed hat while partying in a VIP bungalow with five male and five female friends, the UK's The Sun reports.

Lopez, the former "American Idol" host, now on tour with Enrique Iglesias, was the host of the pool party, just hours before her Sin City concert. She kept the spotlight on herself, walking the red carpet and 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.
