Kim Kardashian has found a new BFF in Stacy Keibler, after Beyonce showed little interest in palling around with reality star. The retired professional wrestler has been linked to George Clooney since July 2011 and the 31-year-old reality star was spotted with her a number of times last week. According to a source, Kardashian and Keibler first bumped into each other at Yankee Stadium last weekend at the Madonna concert, which Kardashian attended with her BFF Jonathan Cheban, who’s also friendly with Keibler. “They’ve known each other for years and have always been friendly, just not best friends,” the New York Daily News quoted a source as saying. During the week, the duo also hung out at the Marchesa fashion show in Grand Central Station, which Kardashian attended with West. On Thursday, the pals were spotted again at The Palladium Jewelry By Jacob and Co. Launch Celebration hosted by W Magazine at Jacob and Co. Flagship’s store in midtown.
