Does the “B” stand for Beyoncé or brrrrr? Because a recent report alleges that the megastar singer immediately turned down the offer when Kim Kardashian asked her to be part of her bridal party. That’s cold.

Though Kim’s fiancé Kanye West has an old and close friendship with rapper Jay Z, it seems Bey has no interest in Kim becoming Ethel to her Lucy just because Kim happens to be marrying her hubby’s BFF. So when the reality star reportedly reached out to Queen B and asked her to be a bridesmaid in her summer wedding, Beyoncé was quick to turn down the offer according to Star (via Hollywood Life).

The two beauties’ relationship has been described as icy in the past, but we were pretty sure they were past all that. In fact, Kim recently attended a Beyoncé concert and appeared to have a blast. However, it’s entirely possible the feeling isn’t mutual. The Star source says that while Bey is polite to Kim and her kin, “she still finds her family unbearable.”

Why does Kim rub Mrs. Carter the wrong way? The “Flawless” singer has gotten increasingly private over the years (especially since giving birth to Blue Ivy), and it would see Kim’s public and sometimes controversial lifestyle rubs Bey the wrong way.

While we can’t speak to the veracity of this story, it does seem a little weird to us that Kim would ask B to stand up for her at her third wedding. When she wed Kris Humphries, the only girls who made it into Kim’s bridal party were family — her four sisters along with sister-in-law Kaela (who we guess got a spot because her name started with the requisite K). Not even Kim’s BFFs LaLa Anthony and Brittny Gastineau made the cut.

What do you think — did Beyoncé burn Kim, or is it another day, another baseless rumor?
