Teresa Giudice lashes out against Sofia Vergara: 'She's an immigrant ... she should be nice'

If you don't know who Teresa Giudice is, you better fake it.

Vergara, the top-paid woman on television thanks to her leading role on "Modern Family," didn't recognize "Real Housewives of New Jersey" star Giudice at a recent event -- and Giudice is still livid.

Giudice described the encounter during a "Getting Real with the Housewives" panel, TMZ reported. According to her, a Bravo publicist asked Vergara to pose for a photo with Giudice. Vergara obliged, but then supposedly said to her publicist, "Why you make me take a picture with that woman?" (Giudice imitated Vergara's accent as she recounted the moment.)

“I never asked for a picture because I’m so not like that, I don’t care,” Giudice said. “She didn’t want to take a picture with me."

Vergara's demeanor seemingly irritated Giudice for a particularly unexpected reason: "Ugh, I can’t stand her, sorry. I hate to say that because I’m Italian, she’s Colombian, she has an accent — she has more of an accent than me! You would think she would be nice, like she’s an immigrant — no, I’m just saying, she should be nice!”

Guidice and Vergara were both guests on "Extra" on October 23, although they didn't appear on-air together.
