Kellan Lutz: Shirtless for 'Abott + Main' & 'Dylan George' - Exclusive!

Kellan Lutz is shirtless sexy alongside model Kate Upton in this exclusive campaign image for the upcoming Dylan George and Abbot + Main lines, taken earlier this year in Venice Beach, Calif.

“I try to always stay active and run regularly, but the most important regimen I do to prep for a shoot is my dieting. Eating the right foods is just as important as working out the right way,” Kellan explained exclusively about prepping for a photo shoot.

“For this shoot, I cut out carbs a week before and ate a lot of chicken and vegetables three times a day, drank gallons of water each day, and during the shoot I would drop down and do pushups and crunches throughout the day to keep the definition needed for each shot,” Kellan added.

The two Fall 2012 lines debut tomorrow (June 6) on dylangeorge.com and abbotmain.com!
