Kim Kardashian, ex-BFF of Paris Hilton, has moved on to another blonde. She and Christina Aguilera were joined at the hip at a party at Avenue for the singer’s album “Bionic” the other night.
A spy said, “Kim made a beeline for Christina on the mezzanine, and they chatted the entire night. They even went to the ladies’ room together. They went crazy when Christina’s new song was played.” Kim is also celebrating becoming a producer after her show starring publicists Simon Huck and Jonathan Cheban was picked up by E!
