MEET THE PUP

Mischa Barton is newly single and looking good, stepping out with a cute new companion she won't leave home without: Charlie, a mixed-breed dog she adopted from The Amanda Foundation, an L.A. animal-rescue group. On July 8, the stylish O.C. actress completed her look – a satin camisole, slim-fit jeans and ankle boots – with her new pooch as she went to lunch with friends in West Hollywood.
