Singer Beyonce has been reported to have dissed reality star, Kim Kardashian, once again behind her back.

The singer greeted the reality star by posting a sweet message and a photo of Kim Kardashian and Kanye West on her Instagram account. The photo was captioned with a sweet message for Kim's wedding day however reports have now surfaced that the "Drunk in Love," singer cannot stand Kim Kardashian and the greeting she posted, was all just for show.

Beyonce isn't a fan of the Kardashian and definitely not a fan of their reality show, "Keeping Up With the Kardashians," as reported by Hollywoodlife.com.

As reported by RadarOnline, a source had spoken the truth saying:

"Bey does not like Kim at all, She's cool with Kanye, but can't stand Kim." And not only that, but the source had revealed that Beyonce thinks Kim is simply using their friendship for fame:

"B calls Kim a 'scandalous social climbing wh*re' behind her back," according to the source.

It seems like Beyonce was never on the "friendly," side when it came to Kim Kardashian. Reports are now saying that this would have been utterly the real reason Beyonce and Jay Z did not attend the wedding of the two. Avoiding being connected to the two as "friends," and not because of the whole elevator incident with Bey's sister Solange Knowles and their feud with Kim best friend, Rachel Roy are said to be few of the reasons why the celebrity couple dissed the wedding in Italy.

Beyonce may be known to hate Kim but now reports are saying that even rapper and husband, Jay Z is getting in on the catfight. As reported yet again by Hollywoodlife.com, a source had revealed that Jay Z thinks "Kimye's" wedding is an entire joke.

"Jay thinks the entire Kimye wedding is a joke and it's being blown way out of proportion," as revealed by the source.

Would this be the beginning of a whole new feud between the two couples?

Who is the power couple now among these two? Fans surely want to know the whole story behind it.
