Photos of Katherine Heigl, Mandy Moore, Alicia Silverstone at Peter Alexander Boutique Grand Opening

Katherine and Mandy Are All About Puppy Love

Mandy Moore, Katherine Heigl, and Alicia Silverstone came out last night to support designer Peter Alexander at the grand opening and benefit of his flagship boutique in LA. Katherine took her adorable puppy Romeo out for the evening, and joked about how her husband won't let her adopt any more pets. Mandy was dateless for the night, but that doesn't mean she's single — apparently she and DJ AM are back together after his accident and were spotted getting cozy at a luncheon.
