The On the Way Down hitmaker was vacationing in Las Vegas with his pals when he lost a game of roulette and ended up with a sketch of Gosling on his calf.
He tells the Las Vegas Review-Journal, "We like to play a game called tattoo roulette. We blindfold each other: 'You get to pick a tattoo for me, and I get to pick a tattoo for you. And you don't get to see it till they're both done.' The only rules are that it can't be religious and it can't offend anybody."
The 30 year old revealed the Gosling portrait during a recent performance in Sin City by rolling up his pant leg for the cameras, but Cabrera admits he normally keeps the new body art covered up.
He adds, "I'm not showing it to Ryan. I do show it off at the pool, though. I'm very proud of it... The best part is he (the tattoo artist) did it portrait style, so it looks like the president in silhouette."
