Mark Wahlberg and Denzel Washington shared scenes with Paula Patton last night on the New Orleans set of 2 Guns. Denzel arrived in casual attire, then changed into a crisp Naval uniform. Mark, meanwhile, showed off his ripped muscles in a tight tank. Mark's dedication to fitness is one of the many reasons he's in the running to be this year's PopSugar shirtless champ. He's up against other well-toned stars like Chris Hemsworth, Joe Manganiello, Tom Cruise, and David Beckham — have you filled out your shirtless bracket yet? Mark's sharing the secret to his chiseled abs and bulging biceps, recently starring in a video detailing elements of his workout routine. The fitness buff is also talking up a line of nutrition supplements he's endorsing, appropriately named Marked.
