The London Olympics have made a permanent mark on British diver Tom Daley.

The 18-year-old Olympian shared a Facebook photo Friday of his new tattoo, the Olympic rings on his inner bicep. Daley poses in the photo with two other athletes who got the same ink, but his cut diver's physique stands center stage.

Other than getting inked, Daley has kept busy after the London Games with his rumored girlfriend, 17-year-old American diver Kassidy Cook.

Immediately following the conclusion of the games on Aug. 12, Cook took a flight alone from Texas to London to be near her new beau. She wasn't able to compete in London herself after a dislocated shoulder kept her sidelined.

Daley's mother told reporters that she didn't know about any serious relationships her son has had, but all evidence points to things heating up between he and Cook. The couple even cuddled up and took in a performance of "The Lion King" together on London's East End on Aug. 15.

Daley has exploded in popularity since the 2012 Games, hosted by his homeland of Great Britain. The diver found success in competition, taking home a bronze medal in the 10-meter men's platform event.
