Rachel Bilson went without a coat while running errands in LA Wednesday. Other celebrities have been taking care of their holiday shopping wrapped up to face the Winter weather, but California girl Rachel was happy to venture out in just a blazer. As the decade comes to a close the show that made her famous, The OC, was named one of Buzz's favorites and in 2010 she'll be back on her familiar stomping grounds of television. She's set to appear on the 100th episode of How I Met Your Mother when it returns in January, but for now she's all about making sure everyone is wrapping up the year on a happy note.
