Paris Hilton and Nicole Richie seem to be friends again. The two were spotted at a Los Angeles restaurant Sunday and now they have agreed to film a fifth season of The Simple Life together. The show’s executive producer, Jon Murray, told The Associated Press, “The thing the viewers love is the two girls together. America, Paris and Nicole are going to camp.” The Simple Life is set to begin production next month and will air on E! next spring. The show will explore “what led to the breakdown in the friendship and maybe some of the misunderstandings and things that got in the way,” Murray said.
