14-time Olympic gold medal winner Michael Phelps helped christen the official 2011 season opening of Encore Beach Club this past weekend at Encore Las Vegas. The champion swimmer led a champagne and medal ceremony at the Strip’s premier daytime destination then, after addressing the veritable sea of lively partiers soaking up the sun and hot scene at the 60,000 square-foot entertainment complex, joined them for a dip and a splash fest in one of the three tiered pools at the luxurious, adult-only dayclub.

Also in attendance was the reigning Miss Nevada, Sarah Chapman, who spent some time poolside with Phelps.
