Ryan Lochte has been having a lot of fun since returning from his somewhat disappointing performance at the 2012 London Olympics. The U.S. Olympic swimmer was recently spotted in Las Vegas where Prince Harry reportedly challenged him to a drunken swim off at a Las Vegas Wynn pool party around 3 a.m.

According to the report, Prince Harry challenged Lochte and they both jumped into the pool, still wearing their jeans, and raced in front of about 5,000 spectators.  Prince Harry lost the race, despite being given a head start.
