Atlantic City, NJ, October 3, 2009 – Mario Lopez turns 36 this week, and he celebrated over the weekend at the Borgata Hotel Casino & Spa with a cake curiously topped with a photograph of the shirtless birthday boy flaunting his ripped abs.  Gives new meaning to the word “beefcake,” doesn’t it? 

During the festivities, the former Dancing with the Stars contestant kept his shirt on, so only his new lady friend, Courtney Mazza, got to see the famous six pack in the flesh.  She sang “Happy Birthday” to him during dinner at Izakaya, and later the twosome whispered and laughed together at club mur.mur.  Once DJ Samanth Ronson hit the turntables, the couple hit the dance floor.
