Ryan Lochte gathered his friends for an Olympics party last night at the London club Chinawhite. He linked up with fellow London 2012 swimmers, including Matt Grevers and Nathan Adrian, to toast the many medals amassed by Team USA in the pool. Ryan personally racked up five, including gold for the 400-meter individual medley and the 200-meter team freestyle. He had another reason to celebrate, too — Friday was Ryan Lochte's 28th birthday! He had the company of some lady friends leaving Chinawhite, but they likely weren't one-night stands. Ryan clarified comments his mom made about his personal habits recently, and said he "dates" but doesn't do one-evening-only trysts. He's among the many athletes enjoying attention from the opposite sex now that the hard work is done. Michel Phelps partied with his medals and a statuesque blonde over the weekend, too.
