Sofia Vergara looked almost unrecognizable when she filmed a scene for Modern Family in Beverly Hills, CA, on Thursday. The normally glamorous star was working alongside costar Ed O'Neill while wearing tattered sweatpants, ratty hair, smeared lipstick, and (shudder) Crocs. We're guessing that Sofia's character, Gloria, gets a serious makeunder in the show's new season. The actress and her cast are back to work on the sixth season of their hit series after taking a break for Summer. Considering that the gang reunited only last week, they probably have a lot to catch up on, including Sofia's red-hot romance with the equally attractive Joe Manganiello . When we caught up with Sofia's costar Eric Stonestreet  before the cast returned to their set, he said that he couldn't confirm that the two are dating but that "it would be fun if he visited the set and everyone gets to punch him in the stomach to test his abs."
