Who's The Daddy? Kris Demands Meeting With Blac Chyna's Other Man

It's been less than a week since RadarOnline.com revealed new claims that Rob Kardashian is not the father of Blac Chyna's baby. And Kris Jenner has already gone full force with damage control!

As RadarOnline.com reported, an insider claimed singer Pilot Jones had been secretly seeing Blac for several months, and could be the real father of her child.

Blac called the claims "lies" in an explosive text rant to RadarOnline.com, but now, "Kris is demanding that Pilot Jones meet with her ASAP," the source said. "If it turns out that Blac Chyna is lying, there will be hell to pay!"

Meanwhile, Kardashian, 29, is STILL refusing to believe that his big-bootied baby-mama-to-be has done any wrong, a source close the Kardashian clan told RadarOnline.com.

However, RadarOnline.com obtained photos that show Blac Chyna and Jones kissing and caressing each other — and text messages that were sent between them within the last month.

"Kris knows that there are two sides to every story and sometimes more," the insider said. "But when she found out that there were photos of Blac and Pilot kissing, she flipped out!"

Meanwhile, as RadarOnline.com previously reported, Rob's famous sisters – Kim, 35, Khloe, 32, and Kourtney, 37 – have already hired a private investigator to uncover the truth.
