Rachel Bilson’s Little Sister is a Shopper-in-Training

Rachel Bilson isn’t letting the wobbly economy stop her from spoiling her seven-year-old half-sister, Hattie.

The former O.C. actress, 27, brought Hattie to Toys R Us yesterday, and the younger sibling wasn’t shy about picking a few favorites from the shelves. Pink ponies and toy cars for all!

Bilson’s clothing line, Edie Rose, must be doing okay for the actress to be able to afford that kind of indulgence.
