Matthew Mitcham, Gay Australian Olympic Diver, Sings 'Family Guy' Theme With Ukulele

He dives! He sings! He plays ukulele!

Just days after he treated his fans to a spirited cover of Beyonce's "Single Ladies," Olympic diver Matthew Mitcham is back at it again -- this time, crooning the theme song to "Family Guy" in a clip apparently filmed in his room in London's Olympic Village.

"I'm just an Olympic diver who likes to strum away in his spare time," Mitcham wrote on his official YouTube page of his earlier clip. Those who complained that Mitcham's "Single Ladies" was shot in dim lighting will be happy to know the button-handsome Australian is not only more clearly visible, but also barechested in his new video.

Mitcham, who is gearing up to defend his gold medal on Aug. 11, is one of just 21 openly gay Olympians participating in London this year -- a fact he doesn't take lightly. "I'm very conscious of how I present myself as a role model," he has said.

Take a look at the openly gay Olympians participating in the 2012 Games below:
