Kim Kardashian and Beyoncé are said to have "barely spoken" to each other at the Made In America Festival over the weekend.
According to the New York Daily News, both women - who attended the gig in Philadelphia to watch their men Jay-Z and Kanye West perform - were allegedly 'frosty' towards each other.
Despite reports that Kimmy and Queen B had bonded after getting off to a shaky start, a source told the publication: "Kim and Beyoncé barely spoke to each other. They were on opposite sides of the stage.
"Beyoncé didn't even acknowledge [Kim] was there until the concert was almost over. [Kim] didn't make any efforts to go speak to Beyoncé either."
The mole added that they briefly had a conversation after the concert, with Kardashian said to be "uncomfortable", spending most of her time with Yeezy and pal, Jonathan Cheban.
They said: "Eventually, the 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. Kim was talking to Jonathan, and Kanye was talking to Jay-Z and Beyoncé."
