Kellan Lutz stayed hot and hydrated leaving the gym after a workout in Sherman Oaks, CA yesterday. He's maintained his muscles in preparation for filming the final Twilight saga installments and showed us the fruits of his labors with a sexy shirtless basketball match earlier in the week. Kellan also lends that famous six-pack to Calvin Klein underwear ads, much to the delight of his fans around the world. One thing Kellan cares about as much as fitness is his beloved dogs Kevin and Kola, though the pups may have to stay behind when he goes on location for Breaking Dawn. In other saga news, his costar Robert Pattinson reemerged in LA with his big bushy beard and we also finally got to meet Renesmee.
