Paris Hilton and Nicole Richie
These two socialites go way back. After growing up together in the posh Bel-Air neighborhood, Nicole Richie and Paris Hilton then documented their wild early years on reality show The Simple Life. Despite not remaining as close as they once were, Richie said in 2014 on Watch What Happens Live, "Paris is somebody that's been in my life since day one. I haven't spoken to her in a while technically, but, if you really want to get into it, my view of a friendship is someone that you don't necessarily have to talk to you every day."
