Retirement from swimming apparently suits Michael Phelps well in the girlfriend department - he's dating Golf Channel's Win McMurry - and the facial hair realm.
As mustaches go, Phelps' is fairly epic by modern standards:
Debuted within an adorable, black-and-white photograph of the Olympic champion and his niece, the new look definitely suits him, don't you think?
Phelps posted the shot on his Instagram today, and we're not sure if it just works because he has 87 gold medals, or because it's just that awesome.
Either way, though, it's en emphatic win. Don't you agree?
