Beyoncé and Kim Kardashian just can’t seem to get along.  

According to a print report from the June 30 edition of In Touch Weekly, Beyoncé, 32, and her longtime rumored frenemy, Kardashian, 33, are allegedly “at war” following the singer's decision to not appear at the reality star’s recent nuptials.

Just days after rumors surfaced that the “Keeping Up With the Kardashians” reality star had referred to her daughter, North West, 1, as being “cuter than” Beyoncé’s own, Blue Ivy, 2, the tabloid is now claiming that the duo are feuding over the singer's no-show at Kardashian’s wedding to Kanye West last month.

“Kim and Kanye fully expected [Beyoncé and Jay Z] to come to the wedding,” said a source close to the newlyweds, adding the couple felt both “embarrassed” and “angry” when the “On The Run” performers vacationed in New York’s Hamptons in favor of appearing at their May 24 affair in Italy. “Kim and Kanye are beyond pissed. Now its a full on feud,” a source said.

While a normally outspoken West, 37, has yet to address his rumored frustrations with his longtime pal Jay Z, he did noticeably remove the rap mogul's name out of two song's lyrics during a performance in Austin, Texas June 7. “Kanye had asked Jay to be his best man but he declined,” said an insider when discussing West’s alleged frustrations. “Not coming to the wedding at all was just adding insult to injury.”

While West and his “Keeping Up With the Kardashians” star beau may be fuming over their A-list guests being MIA at their overseas affair, insiders claim the “Single Ladies“ singer could care less about the couple’s upset. “She can’t stand Kim” an insider said. “She thinks Kim got famous from a sex tape while Beyoncé has worked since she was five to get where she is today.”

Despite Beyoncé's expected attendance at the nuptials (some reports hinted that the hit maker would have been paid for appearing) insiders claim the singer felt that being a guest ultimately would have hurt her image. “Bottom: line Beyoncé though being photographed at Kim’s wedding would have made Kim look good and her bad,” a source said.

While Kardashian’s mom, Kris Jenner, 58, has since referred to Beyoncé and Jay Z’s failure to attend the ceremony as a non-issue, insiders claim this is officially the end of the foursome’s public niceties. “I have a feeling you won’t be seeing them on double dates anytime soon,” a source said.
