"Not working." The upcoming star showed off his ripped physique on Instagram, posing on the set of "Fury," his new movie with Hollywoods finest, Brad Pitt and Shia LaBeouf. Going shirtless is becoming quite the habit for the 27-year-old -- the dashing son of Clint Eastwood recently took his shirt off for the cover of Town and County magazine, appearing to be his father's double back in the day.
