Kellan Lutz arrived in Washington DC last night and was out this afternoon to make a charitable appearance at an event celebrating the 100 best communities for young people. The Twilight star is back in the nation's capital after volunteering there earlier this Summer too. He's lately been busy traveling the world, which included a stop in Israel, and doing his bit to help in New Orleans. Soon, though Kellan will be back to work reuniting with Robert Pattinson and Kristen Stewart on the set of Breaking Dawn. Fans who can't wait to see more Kellan got a treat yesterday when his latest round of sexy Calvin Klein ads debuted.
