Before the world was keeping up with Kim Kardashian and her family on TV, she was the close party pal of Paris Hilton. The two regularly hit the red carpet together and ran in the Hollywood socialite circle that included Nicole Richie and Lindsay Lohan. Reportedly, Kim and Paris's friendship ended in 2007 after Kim became the new celebrity on the block. Things got even more heated in April 2007 when Paris told a Las Vegas radio host, "I would not want [Kim's butt] — it’s gross! It reminds me of cottage cheese inside a big trash bag."
A source told Us Weekly later that year that Paris's beef with Kim "is 100 percent jealousy," adding, "Kim is not only doing what Paris did, she's doing it better."
Though the two still don't hang out, Paris did congratulate her ex-BFF Kim on her first pregnancy back in January 2013, telling reporters, "I'm really happy for her." They also let the world know there wasn't any bad blood between them in 2014 when Kim shared an Instagram photo of her and Paris partying in Ibiza together, like the good old days.
