Beyonce's Phony Wedding Well-Wishes To Kimye — Singer Calls Kim A Scandalous Social Climbing Wh*re Behind Her Back, Claims Source

Kim Kardashian loves calling Beyonce and Jay Z her BFFs, but behind closed doors an insider exclusively tells RadarOnline.com that the "Drunk in Love" singer can't stand the sex tape star and thinks she's just using them to achieve social status.

According to a pal close to the hip hop couple, Beyonce doesn't mind Kardashian's new husband, Kanye West — who Jay has co-headlined with on their Watch The Throne tour — but doesn't care at all for the Keeping Up With The Kardashians star.

"Bey does not like Kim at all. She's cool with Kanye, but can't stand Kim," the source told Radar.

And what's more, the source claims, "B calls Kim a 'scandalous social climbing wh*re' behind her back."

Perhaps proving her point, Beyonce and Jay snubbed Kardashian and West's wedding overseas last weekend.

But the catty words behind Kardashian's back are a far cry from the heartfelt well-wishes Beyonce, 32, left for the couple via Instagram on their May 24 wedding day.

A photo of Kardashian, 33, West, 36, baby North West was posted with the caption: "Wishing you a lifetime of unconditional love. God bless your beautiful family
