Rachel Bilson's blonde moment

Rachel Bilson's blonde new look

Has Rachel Bilson done a Lily Allen and dyed her brunette locks blonde?

That was our first thought when these pictures pinged into our inbox, showing the OC star sporting a platinum bob, complete with blunt fringe.

To our relief, Bilson is in fact wearing a wig, on the set of new movie NY I Love You. The film is currently shooting in New York, and features an ensemble cast that includes her rumoured real life love interest Hayden Christensen, along with Orlando Bloom, Christina Ricci, Natalie Portman and Shia LaBeouf.

Lets hope she doesn't take inspiration from her new blonde look, as we much prefer her regular auburn wavy locks.
