Anna Kendrick had her passport in hand as she walked through the airport in Vancouver yesterday. She's the latest Twilight star to head out of town as work on the series winds down. Kellan Lutz and Ashley Greene were spotted catching flights yesterday, as were Jackson Rathbone and Nikki Reed. The official wrap date isn't apparently until next week, but some of the cast already celebrated the end of filming. Kristen Stewart partied with Robert Pattinson, Taylor Lautner, and his girlfriend, Lily Collins, earlier this week, and the event happened to coincide with Kristen's 21st birthday. She's not the only star ringing in the milestone recently, since today is Emma Watson's birthday as well.
