There has always been rumors that Kim Kardashian and Beyoncé are not the best of friends even though the men in their lives are really close friends. Now, Star magazine is claiming that Beyoncé embarrassed Kardashian by "refusing" to be a bridesmaid in her wedding.

A source told the magazine that the "Keeping Up With the Kardashians" star called the Queen B and asked her to be in the wedding by Beyoncé rejected the offer.

"Kim has been boasting to pals that Bey wants to be a bridesmaid, but Beyoncé turned her down flat. Bey doesn't want anything to do with the Kardashian clan," a source told the magazine. "From sex tapes to crack addicts, they're too controversial. Beyoncé doesn't even take Kim's calls, so she was shocked when she got a voicemail begging her to be a bridesmaid."

This isn't the first time the "XO" singer has reportedly dissed Kanye West's fiancé. According to a rumor last year, the two ladies attended the "Made in America Festival" in Philadelphia but barely spoke to each other.

"Kim and Beyoncé barely spoke to each other. They were on opposite sides of the stage. Beyoncé didn't even acknowledge [Kardashian] was there until the concert was almost over," a source told the New York Daily News (via Hollywood Life).

The source claims that Bey and Kardashian eventually made small talk in the dressing room "but Kim was uncomfortable. She clung onto Kanye the entire time and didn't say much."

"[Kardashian] was talking to Jonathan, and Kanye was talking to Jay Z and Beyoncé," the source said.

No one knows for sure if Star's story is true but the 33-year-old reality star has spoken about her relationship with Beyoncé in the past. During a 2012 radio interview with Sway, Kardashian said she is not feuding with Jay Z's wife and thinks she is one of the sweetest people in the world.
