Kim Kardashian's boyfriend might be best friends with Beyonce's husband, but that does not mean friendship has blossomed between the two ladies.
Sources say that Beyonce wanted nothing to do with Kardashian at a Labor Day weekend Jay-Z concert where Kanye West performed.
On Saturday, Beyonce and Kardashian were both in attendance at the Made in America Festival in Philadelphia to support their men. However, despite Kardashian's repeated attempts to become part of Queen Bey's inner circle, the 16-time Grammy winner reportedly snubbed the reality star.
"Kim and Beyonce barely spoke to each other," a source told the NY Daily News. "They were on opposite sides of the stage. Beyonce didn't even acknowledge [Kardashian] was there until the concert was almost over."
Eventually, the two women "made small talk in the dressing room, but you could tell Kim was uncomfortable. She clung onto Kanye the entire time and didn't say much," another source told the NY Daily News. Adding, "(Kardashian) was talking to Jonathan, and Kanye was talking to Jay-Z and Beyonce." West was a surprise guest during Jay's set.
The reality star tweeted photos from the Philly show, but none included Jay or Bey.
West has been dating Kardashian for just five months, while Jay-Z and his superstar wife have been married for more than four years and have an 8-month-old daughter, Blue Ivy, together.
In May, the newspaper reported that Kardashian was dying to be friends with the "Love On Top" singer.
"Kim wants to travel everywhere with Kanye, but she's also trying to do whatever she can to get close to Beyonce," a source told the paper. "So, if Bey and Jay are going, she's going."
But rumors of a riff of a Beyonce-Kardashian beef first flared back in June. Beyonce and Jay-Z reportedly wanted nothing to do with the "Kimye" romance. However, Kim was seen backstage at Beyonce's Atlantic City concert and a rep for the E! star told RumorFix, "This story is not true, Beyonce even invited Kim to her Atlantic City concert. They are great friends ... this story is just ridiculous."
