Celebrity Best Friend Breakups: Bye-Bye, Besties! (PHOTOS)

Before she became a reality television personality (and celebrity) in her own right, Kim Kardashian was simply known as one of Paris Hilton’s many socialite pals. But as Paris’s star began to fade and Kim and the Kardashian Klan landed a series of reality shows on E!, Kim quickly outshone her friend, and jealousy reportedly took over. In 2010, a source told Us Weekly that Paris was pissed after Kim snubbed her at a club, and the friends drifted apart. However, Paris now wants everyone to know that she’s “happy” about Kim’s pregnancy.
