Looks like the Secret Life of Walter Mitty star just revealed his own brawny secrets. Ben Stiller let his ripped guns out while enjoying the fun and sun on the beaches of Hawaii. Spotted shirtless and drying off after a day of paddleboarding, the 48-year-old funnyman known for his Blue Steel look in Zoolander also served up some abs of steel in his multicolored, floral board shorts. Stiller was spotted paddleboarding before on a holiday getaway back in 2012 with his family in Kauai.
