A Beverly Hills shop owner is getting some celebrity help in the search for her dog, which was seen on surveillance video apparently being snatched by a pregnant woman.

Actress Hilary Duff, a friend of Switch boutique owner Julia Cohen, took to social media this week to urge her followers to help locate the little white Maltese.

Duff tweeted the following:

The video aired by KABC-TV showed a woman with a girl follow the dog on a sidewalk near the boutique, disappear around a corner, and then re-emerge with Charlie in her arms and walk away. Witnesses say she was pregnant.

Comedian George Lopez and singer Lance Bass also tweeted about the stolen dog:

A $2,000 reward is being offered for Charlie's safe return.
