Beyonce Solange Knowles

A Knowles family feud is reportedly brewing, and it's all over Kim Kardashian.

The singer and the professional celebrity have been spotted out together multiple times over the last couple weeks, appearing to actually enjoy one another's company, and Solange Knowles is far from happy about it.

“In Solange’s eyes, Beyonce is a stand-out star, a premier singer of our time, whereas Kim is just a reality TV star who only got famous after a sex tape was leaked,” a source tells The National Enquirer, pretty much just reciting facts.

Following photos of Kim and Beyonce dancing as a pair at a Kanye West/Jay-Z concert last month, the siblings reportedly got into a blowout.

“[Solange] called Beyonce out on it, and they had a fight over Kim," says the insider. "It culminated with Beyonce telling Solange she can be friends with whomever she wants.”

Kardashian also gave Beyonce a $5,000 bracelet for daughter Blue Ivy recently, one inscribed with "Love Auntie Kim." Even Beyonce thought it was a tad much.

Beyonce was at the center of controversy last night - through no fault of her own.

If you missed it, that jackass Kanye West decided to interrupt Taylor Swift at the MTV Video Music Awards, proclaiming that Beyonce was more deserving of Best Female Video after producing THE GREATEST VIDEO OF ALL TIME!!!!!

To her credit, Beyonce was horrified, then reached out to Swift with a classy gesture after the incident. Yeah. Even she thinks Kanye West is a moron.

Moving on to more important things, girl was lookin' flat out FIERCE last night in that red dress. So vibrant. The plunging neckline and the shoes? Wow.

Not to be outdone, her sister Solange showed up and ... well, she was probably outdone. But that black number with the shaved head looked cool.
