Kellan Lutz  looked happy to be reunited with his two dogs, Kevin and Kola, out for a walk in LA yesterday after a busy Summer of international travel  for the actor. Kellan's four-legged buddies led the way, though it's hard to miss Mr. Lutz's well-toned muscles. Those arms and abs have done well for him recently between his Calvin Klein underwear modeling gig  and his next-to-nothing wardrobe for Immortals . Meanwhile, Kellan's personal life is heating up as he and AnnaLynne McCord  continue to semi-grace red carpets together  in California and around the world . Last night he arrived solo at Lucky Strike Bowling Alley for a celebrity bowling event, though this evening should be all about his lady since it's AnnaLynne's 23rd birthday.
