Kellan Lutz Goes Shirtless!

Kellan Lutz was just spotted running with his dog shirtless! The Twilight actor is said to be bulking up for his upcoming role in Eclipse.

"I’m putting on a lot of weight as fast as I can, going to the gym and doing fight training and a lot of stunt work. I hate to run so for all the runners out there, I hate you. But I love to swim. I’m a fish, I have a pool in my backyard so every morning I will go swimming, even when it’s colder I’ll try to. I’ll have my dog swim with me but usually she doesn’t go under the water so we usually play a game… I play with my dog for a workout. It’s great. A lot of times I’m a loner, so I have to play games with myself,” Lutz explains.
