Kellan Lutz flashed his pearly whites and sexy tan as he arrived at LAX yesterday. He's stopping at home, but Kellan plans to spend the next few months traveling the world until production on Breaking Dawn gets started in November. Kellan has been enjoying some downtime lately, hitting the links with friends and trying to bring attention to his charity on Twitter. Exercise is still a priority for the actor, and all the hard work has paid off - Kellan has earned a spot in the Elite Eight of our Hottest Shirtless Guy competition! He's up against Zac Efron, so make sure to vote and get entered to win Tom Ford sunglasses.

Kellan Lutz joined friends on Saturday to hit the links at the Resort at Pelican Hill in Newport Beach, CA. He managed to get some exercise with his pal after a week of hitting the gym back in LA solo. Kellan had some downtime after a recent stint at Comic-Con promoting his upcoming projects, including Immortals, Warriors, and Love, Wedding, Marriage. His girlfriend, AnnaLynne McCord, meanwhile, chatted up 90210 with a cameo at the TCA - she spoke to us about her favorite Summer blockbuster, and, surprisingly, it wasn't Eclipse!
