Paris Hilton and Nicole Richie's friendship may be over, but their reality show isn't. The Simple Life, which was dumped by Fox, will be back for a fourth season on the E! network. The show's new season is titled " "The Simple Life: Till Death Do Us Part."

According to an E! press release:

The upcoming season of all-new episodes on E! will put the girls to the matrimonial test as it's "you are my wife . . . hello married life" for the jetsetting playgirls. In each of the 10 new episodes, Paris and Nicole will take turns playing the traditional role of wife and running a household. There will be cooking, cleaning and all the other duties required to make a house a home. In addition, as "wives," Paris and Nicole will have responsibility for the children, and each family will ultimately decide which of the heiresses is a "keeper."

Paris cooking and cleaning? This should be interesting! As you may have noticed, season 4's "Wife Swap"-like concept does not require that Paris and Nicole work together like they did during the first three seasons of the show. The former best friends are famously feuding and refuse to speak to each other.
