Chris Pratt Bulks Up for 'Guardians of the Galaxy' (PHOTOS)

Chris Pratt shows off his newly muscular body while running some errands and picking up coffee at a local Starbucks on Friday (May 3) in Hollywood.

The 33-year-old actor’s hard work in the gym is definitely showing off and we can’t wait to see how great he looks in his upcoming film Guardians of the Galaxy!

Chris bulked up for his role in last year’s Zero Dark Thirty but then had to put more weight on to shoot Parks and Recreation. Check out his shirtless pic below.

Chris and his wife Anna Faris made an appearance with their baby boy Jack in a celebrity lip-sync video of Zach Sobiech‘s song “Clouds,” which has been spreading around the internet this weekend. The family appears alongside such stars as Sara Bareilles, Bryan Cranston, and many others to help honor Zach, who was diagnosed with a rare form of bone cancer and only has months to live.
