The Simple Life is filming again, though its stars aren't speaking

After having feuded publicly without ever really stating the cause of their great divide, The Simple Life stars Paris Hilton and Nicole Richie were back in action for their show this week – reportedly keeping their distance and not speaking to one another while the camera rolled, says the New York Post.

For the fourth season of the fish-out-of-water reality program, the two will also lead separate lives. In homage to Wife Swap, Hilton and Richie will absorb different cultures in Los Angeles and move in with Hasidic Jews and a Korean family, says the newspaper.

After three years on FOX, the show will be moving to E! when it comes back.
