Reese Witherspoon headed to a flight at LAX yesterday. She had help from a driver and bodyguards unloading her bags from her SUV, but went through security solo. Reese headed out of town after recently wrapping up a press tour for This Means War that took her overseas to Paris and London. She made time for friends in the UK though, and met up with Gwyneth Paltrow and Stella McCartney for dinner at The Arts Club. Since then, Reese popped up in NYC, where she reportedly checked out the Broadway hit, Book of Mormon. Her most recent getaway may mean she'll miss the Oscars fun in LA this weekend, but she's been in on the action as one of many hot Academy Award winners in the past. View Slideshow ›
