Kim & Beyonce's Frenemy Feud EXPLODES Over Baby Battle

Kim Kardashian and Beyonce's cold war is on AGAIN, RadarOnline.com has learned, after Jay Z's wife blindsided her frenemy with her baby news.

According to an insider, Beyonce deliberately kept Kanye West's wife in the dark about the news she's expecting twins.

“Beyoncé does not trust Kim with her personal secrets and keeps her at arm's length,” an insider told RadarOnline.com. “Kim isn’t part of Beyonce's inner circle and never will be.”

As RadarOnline.com reported, 35-year-old Queen Bey and hubby Jay Z, 47, have a long-standing rivalry with Kardashian and West.

In fact, it was just a few months ago that West, 39, verbally attacked the couple on-stage during his “Saint Pablo” tour.

After Beyoncé broke the internet with her pregnancy announcement, Kardashian, 36, took to Twitter to try and steal the spotlight back. Her coy posts even had some followers convinced SHE was pregnant as well!

“Kim thinks she’s a bigger star than Beyoncé,” a source told RadarOnline.com at the time. “She is the biggest star in the world.”

And while celebs were tweeting and sending congratulations to Beyoncé and Jay Z, Kimye kept deliberately quiet.

“The fact that Beyoncé is going to have more kids than Kim once her twins are born absolutely drives Kim nuts!” a source told RadarOnline.com.
