Jake Gyllenhaal slipped out of his tee yesterday to soak up the sun shirtless with a lady friend by a hotel pool in LA. We've had a few great peeks at Jake's impressive six-pack in Prince of Persia, and it looks like he's been keeping his ab region in top shape! He managed to get in some rest before his big evening out with us at a special screening of his movie, where Jake showed off his sweet side by bringing a birthday cake for our newly 25-year-old contest winner! He also teased the crowd pretending he was going to show off those abs, but he ultimately kept his top on. It was an exciting night for all and was Jake's latest in a string of promotional events for his Summer blockbuster that hits the big screen next Friday.
