Michael Phelps — Yeah, I Went Clubbing with My GOLD MEDALS!!

exclusive 0806_michael_phelps_gold_medals_splash_launchMichael Phelps took three of his closest friends out clubbing in London this weekend — gold medal, gold medal and gold medal.

Just hours after swimming the last race of his career, Phelps — the greatest Olympian in the history of the Olympics — hit the party scene in Soho … along with 3 of his 18 gold medals … and a mystery blonde.

Phelps and his medals partied responsibly … after they partied themselves out, they all piled into the backseat of a waiting SUV and got a ride home.
