Rob Betrayed! Kardashian Is NOT The Father Of Blac Chyna's Baby, Insider Claims

Blac Chyna could be about to lose her place in the Kardashian empire: According to an insider, Rob Kardashian might not be the real father of her baby — because she's been seeing another man behind his back!

A source told RadarOnline.com exclusively that Chyna, 28, has secretly been hooking up with singer and former Glee star Pilot Jones for several months. RadarOnline.com viewed a series of intimate photos of Blac Chyna and the former Glee star kissing and caressing each other.

In addition, Jones and Chyna were spotted clubbing together back in March, amid rumors that she and Kardashian, 29, had suddenly split. Jones later posted this video from the night out:

A rep for Jones told RadarOnline.com, "They're definitely great friends and they've known each other for a while."

Indeed, RadarOnline.com has viewed other photos of the couple out clubbing together in March 2015, long before Kardashian was in the picture.

In addition, RadarOnline.com has confirmed the the pair have been in frequent text communication in recent weeks.

Said the source, "When that baby comes out, it's going to be brown! The truth will come out eventually. Pilot is the dad." Blac Chyna is due next month.

Jones's rep declined to comment on the paternity rumors. Blac Chyna did not immediately respond to RadarOnline.com's request for comment, but previews for Rob & Blac have suggested that she'll take a paternity test later in the season.
