Michael Phelps was spotted at the Encore Beach Club in Las Vegas last weekend. On April 16, the 25-year-old Olympic gold medalist proved he knows how to have fun in a pool. He certainly wasn't setting any records at the Encore's pool party, which kicked off their 2011 season.

Phelps, since an incident in 2009 when he was pictured with a bong, hasn't had the cleanest image. He was temporarily suspended by USA Swimming and lost his endorsement deal with Kellogg's. But apparently the swimmer still likes to have fun – and how could he say no to a pool party? Phelps even reportedly played a DJ set during the festivities.

With the 2012 Olympics approaching soon, Phelps will probably have to leave the parties behind for a while and go back into training. Chances are he will ditch the goatee when he competes for more gold medals and world records.
