It seems that reality star Kim Kardashian and superstar Beyonce will not be best friends anytime soon.

Though their men-Kanye West and Jay-Z, are best friends and business partners, the two women, 'barely' speak to each other, according to a source who spoke to the Daily News. 

Both in Philadelphia to watch the rappers perform during the Made in America festival, a source said, "They were on opposite sides of the stage. Beyonce didn't even acknowledge [Kim] was there until the concert was almost over."

"Eventually, the women made small talk in the dressing room, but you could tell Kim was uncomfortable," the source went on to say.

At the BET 2012 awards earlier this year, the two couples sat together, but even then, Beyonce and Kardashian kept far away from each other, though Jay-Z and West spoke and laughed throughout the awards ceremony.

While Kardashian seemed to be make an effort to win over Jay-Z and Beyonce at the hip-hop show, during the Made in America Festival, she did not make any efforts to speak with Beyonce, the insider said. Instead, she spent the majority of her time with West and her best friend Jonathan Cheban.

Jay-Z organized the festival, which also featured Rita Ora, Santiago, Drake, Run DMC, and Pearl Jam.
