New Besties Alert! Christina Aguilera & Kim Kardashian

KK can usually be found kicking it with her reality star fam, but lately Kim Kardashian has been hanging out with a new crew, including Christina Aguilera.

After chatting it up at Aguilera's Bionic release party in New York on June 9, the ladies headed south for a mutual friend's bachelorette party at LIV Nightclub, and finished off the weekend poolside at the Fontainebleau Hotel.

"I'm obsessed with her new album," Kardashian later blogged. "Her voice is one of my all time favorites."
