Kellan Lutz had his grandfather over yesterday to prep for the big LA premiere of Eclipse. The actor bared his muscular arms as he headed outside to meet the elder Lutz, who also ran into Kellan's girlfriend AnnaLynne McCord. Kellan showed off his brand new Audi and even sweetly let his grandpa take it for a spin. AnnaLynne and the Lutzes then headed over to the main event, where Kellan thrilled the crowd by once again flashing his Calvins. Kellan sweetly thanked his family for accompanying him on his big Twilight night, but it looks like the group called it an early one and skipped out on the afterparty Rob, Kristen, and Taylor all attended.
