Rachel Bilson  touched down at LAX yesterday after a couple of weeks away from home, carrying her studded Burberry  bag and sporting a military-inspired look. The actress is taking a brief break before she jets off again to the East Coast for the Tribeca Film Festival , where her Karl Lagerfeld-directed Magnum ice cream ad will make its debut. The duo shot the spots in Paris last month, and Rachel will be in front of the cameras again shortly as she gears up for her TV show Hart of Dixie. Rachel is one of several stylish actresses who will make their return to the small screen this Fall, with Zooey Deschanel  and Kerry Washington also filming new pilots. Rachel is clearly busy focusing on her wide range of fashion and entertainment projects lately and is apparently a single lady again, with more reports that she and Hayden Christensen  have called it quits for good.
