It’s the feud that never ends!

After years of trying to out-do her frenemy Beyoncé, Kim Kardashian is done with trying to keep up with the Carters! Sources exclusively reveal to In Touch that Kim is ready to go to battle after she and her husband Kanye West were snubbed by Bey and her husband JAY-Z.

“Kim was desperate for Beyoncé’s friendship, but that never happened. Now she’s furious — she wants revenge,” a Kim and Kanye insider tells In Touch. “Kim says this is war, and she’s ready to fight dirty.”

The insider explained that Kim is finally fed up with trying to be nice to the Carters — especially since Jay took a nasty jab at her hubby on his latest album, 4:44. Jay called out Kanye in the lyrics to his new song “Kill Jay Z” and he even mentioned Kayne’s mental health issues that lead to his hospitalization last fall.

Of course, Kanye was upset that his friend hit him with a low blow in such a public way — but Kim was even more upset. This is just the latest incident in a long line of rude gestures from Bey and Jay over the years — dating all the way back to the time they didn’t show up for Kimye’s 2014 wedding.

Kim also spent years trying to arrange playdates for her four-year-old daughter North and Bey’s five-year-old daughter Blue, but on the few occasions where they did get the kids together, Kim said Bey made her feel “insignificant and inferior.”

But now, the mom-of-two is done with trying to impress the Carters — and she’s not playing nice anymore.

“She sent Beyoncé and Jay a $100,000 gift basket to celebrate the arrival of their twins,” the source reveals. “Then Jay’s album came out. She’s considered asking for the gifts back!”
