Michael Phelps joined fellow swimmers Natalie Coughlin, Chad Le Clos, and Alexander Popov at a special Omega Spotlight on Swimming soiree in London yesterday. He was without girlfriend Megan Rossee, who has been in England showing her support during the Games. Michael and Megan made their first official public appearance on Monday at a Speedo event, after the duo reportedly started dating in February. Now that Michael, who is the most decorated Olympian in history, has finished competing, he's turning his attention to life after swimming. Michael says he's not ruling out Dancing With the Stars, but he does want to take time to relax and travel.
