Is there a new celebrity feud in town!? Apparently so, and the latest rumors say its between Kim Kardashian and Beyonce Knowles!

Both ladies were at Philadelphia's Made in America concert over the weekend where their men Kanye West and Jay-Z were performing. However, they reportedly weren't as friendly at the event as they've been in the past, according to the NY Daily News.

"Kim and Beyonce barely spoke to each other," a source tells the paper. "They were on opposite sides of the stage. Beyonce didn't even acknowledge that Kim was there until the concert was almost over." The source adds that Kim didn't make an effort to chat with Beyonce, either, although there was some "awkward" small talk in the dressing room afterwards.

Hmmm... let's break this one down! Kim and Beyonce are both divas (let's be real), so a sudden feud is possible. However, the two got along great earlier this summer at the BET Awards, where Beyonce, Kanye and Jay-Z were all nominated and Kim came along for support. I'm going to have to rule this one as still up in the air -- and cross my fingers that it isn't true!

Do you think Kim and Beyonce are feuding?
