Patrick Dempsey greeted a group of young fans outside a grocery store in LA yesterday. The six girls, who also seem to be Selena Gomez fans, squeezed in next to the Grey's Anatomy star to snap a photo. Patrick's home again after a recent stint behind the wheel for charity in Miami, and he was back to being philanthropic at Sunday's John Varvatos Stuart House Benefit alongside his wife Jillian, James Van Der Beek, and Zoe Saldana. The actor's gearing up for a special musical episode of his series on March 31, though he apparently won't be belting out too many of the iconic ballads himself. His costars Ellen Pompeo, Sara Ramirez, and Kevin McKidd will, however, showcase their vocal talents, so make sure to catch up on past episodes before the singing and dancing airs in two weeks.
