(TMZ) - Michael 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.
