Rachel, is that really you?

The OC
star Rachel Bilson was spotted on the set of her latest film sporting an all together different look to the California cool style that the star is famous for. She swapped her laid-back look for a mid-riff baring cardigan, high-waisted hot pants and some very big curls for her role in The To Do List.

We can't forget to mention the pink accessories either; plastic hoops, flip flops and a fluffy cardigan completed the actresses outfit in between takes. Thank goodness she was only wearing this ensemble for professional reasons...
