chris-pratt-shirtless-instagram-gotg (3)Parks and Recreation’s Chris Pratt has undergone a breathtaking physical transformation for his starring role in the upcoming Marvel film, Guardians of the Galaxy.
The 34-year-old shows off his ripped body on Instagram by posting a shirtless photo of himself, and blames his brother for making him post the “douchey” photo. Pratt shares his current weight loss secret to six months without beer.
Making over his body for each time he plays a new character has become old hat for the  actor. According to Vulture Pratt “gained weight for Moneyball, got fit for Zero Dark Thirty, [and] packed on some more pounds for Vince Vaughn’s Delivery Man.”
