Rachel Bilson Commences Opening Ceremony

Rachel Bilson and a gal pal start up their shopping spree with some coffee and bagels before heading over to the Opening Ceremony boutique in West Hollywood on Tuesday (September 1).

On Friday, 90210 starlet Shenae Grimes also shopped at Opening Ceremony.

Rachel, 28, has a bit of a mess on her hands: her future brother-in-law Tove Christensen was arrested earlier today in Hollywood for felony assault with a deadly weapon.
