LAS VEGAS >> The London games may be over, but Britain’s Prince Harry isn’t letting Team USA get away with the swimming gold that easily.

The royal challenged Ryan Lochte during the American swimming champion’s 28th birthday party Monday at a Las Vegas pool.

Las Vegas Sun columnist Robin Leach reports the prince stripped down to his jeans and gestured for others to clear the way for the contest at the XS nightclub pool at the Wynn resort.

As predicted, the 11-time Olympic medalist won.

The race wasn’t the prince’s only paparazzi-worthy moment during a wild weekend partying in Las Vegas. Photos leaked online show the redhead naked and cozied up to an unidentified woman during a game of strip billiards in a hotel suite.
