Why Paris and Nicole are BFF's Again

The real reason Nicole Richie is pals again with Paris Hilton is because Hilton won't interfere with any bad habits she may have, friends say. A source who was there when the duo showed up arm-in-arm at the Volkswagen Concept party in L.A. the other night said Richie dumped her stylist Rachel Zoe because Zoe, Richie's former friend Mischa Barton "and a few others tried to stage an intervention and tell Nicole to get some help about her weight. Nicole was so hurt that she ran back to Paris and ditched those trying to intervene in her life."
