Big sis Rachel Bilson gets in some girl bonding time and takes care of her adorable half-sisters Hattie and Rosemary on Wednesday (July 28) in Los Feliz, Calif.
The trio picked up a bite to eat at hamburger franchise Johnny Rockets. Afterward, they picked up some supplies from Party City.
A few weeks ago, Rachel and her step-mom Heather took the girls to visit the animals at the LA Zoo & Botanical Gardens.
