Kate Walsh is a Gelson's Girl

Kate Walsh slips into her strappy wedges and denim shorts to do some grocery shopping at Gelsons supermarket on Saturday (May 16) in Los Feliz, Calif.

The 41-year-old Private Practice star threw a birthday party for Sally Ann Brooks, her good friend (and onetime Grey’s guest star), at BoHo, a new gastropub in Hollywood. It was a Grey’s Anatomy cast reunion as T.R. Knight and Justin Chambers were on hand to celebrate with their significant others. While Justin stayed near his wife Keisha, T.R. was equally affectionate with boyfriend Mark Cornelsen and “let [him] take a seat on his lap,” a guest tells People.
