Prince Harry challenged United States gold medal swimmer Ryan Lochte in a race at a Las Vegas pool party. According to reports, the young Prince jumped into the pool wearing jeans around three in the morning at the VIP pool party as he prepared himself for the swim challenge.

The member of the Royal Family got a head start on Lochte as the Olympic Champion patiently counted to three before easily beating Prince Harry with his powerful breaststrokes. This is actually not the first run-in of Prince Harry with an Olympic star. Previously, the handsome Prince claimed that he won after racing superstar runner Usain Bolt during his visit to Jamaica.

Ryan Lochte won 11 medals at the 2012 London Olympics where he famously showed off his diamond-studded American flag grill. According to reports, Lochte was partying in Vegas for his 28th birthday party celebration and he gave Prince Harry a good-natured hug after their race in the pool while the crowd of partygoers looked on.

Meanwhile, Prince Harry has been living it up in Las Vegas. He attended a party earlier in the evening at the MGM Grand's Wet Republic club that celebrated the launch of Jennifer Lopez's new tour with Enrique Iglesias. Prince Harry was reported to be shirtless at the party as he sipped vodka and chatted with some guests while keeping a low profile as actress and singer Jennifer Lopez stole the show.

"Dancing with The Stars" contestant Maria Menounos revealed to Us Weekly that she spotted the casual looking Prince by the pool. "He walked by us," Menounos shared. "I was with J-Lo in her cabana and he was a couple cabanas down. He seemed like he was just having a good time!" she further added.
