When we last saw British diver Tom Daley, he was a young 14-year-old Olympian. He'll be 18 at the Olympics this summer in his home country. What a difference four years makes. He jumped in front of the camera recently, along with some other British Olympic hopefuls, to lip sync to LMFAO's "I'm Sexy and I Know It." Video after the jump. Hat tip to Towleroad.
