Actor Chris Pratt is flaunting his muscular new body after cutting beer from his diet to shape up for forthcoming superhero movie Guardians Of The Galaxy. The Zero Dark Thirty star indulged in junk food last year (12) in a bid to pack on 60 pounds (27.2 kilograms) to play an overweight lawyer in new Vince Vaughn comedy Delivery Man, but he has spent the past six months trying to shed the excess fat and he's showing off the results of his strict diet and workout plan with a photo on Instagram.com. Pratt, who is married to actress Anna Faris, snapped a picture of himself topless in the gym and shared the image of his six-pack abs with fans on Sunday (07Jul13). In the accompanying caption, he writes, "Six months no beer. Kinda douchey to post this but my brother made me." Pratt has been getting fit in preparation for his lead role in Marvel Comics' Guardians of the Galaxy, in which he will play Peter Quill/Star-Lord. The movie, co-starring Zoe Saldana, Glenn Close and Benicio del Toro, is due to begin filming later this year (13).
