What happened in Vegas didn't stay in Vegas.
On your marks, Ryan Lochte and Prince Harry!

Britain’s party prince dove into some serious competition on Monday night, when he challenged Olympic champ Lochte to a royal race during a late-night Las Vegas pool party.

Stripping down to just his jeans, Harry hopped in the crowded water and gestured for others to clear the way for the head-to-head showdown at the Wynn Hotel’s XS nightclub.

So who took first place?

Not so shockingly, the 11-time Olympic medalist won.

But that wasn’t the only contest Prince Harry lost during his wild weekend in Sin City.

After he was apparently defeated in game of strip billiards, a camera caught the rogue royal cavorting nude with a mystery woman in his VIP hotel suite. In the the blurry snaps, originally published by TMZ, Queen Elizabeth‘s grandson, 27, covers his crown jewels as he clings to the nearly naked female.

According to TMZ, the snaps were taken after third-in-line to the British throne and his pals invited some women, who have not been identified, to their VIP suite at the MGM Grand.

See Lochte speed ahead of Prince Harry in the pool in the video above.
