Chyna Cheating Already? See Why Rob Doesn't Trust His Baby Mama

Dream Kardashian isn't even a month old, and her parents are already at war! Blac Chyna's cheating scandal and Rob Kardashian's massive insecurities have only intensified problems in the rocky relationship in recent weeks, according to an insider. Click through RadarOnline.com's gallery to find out why Kardashian is worried that his brand-new baby mama could still betray him.

Kardashian has struggled to feel secure in his relationship with his baby mama, but the birth of their child has only intensified his raging jealousy, an insider told RadarOnline.com. "Rob is paranoid about nearly every single thing that Chyna does now," a source close to the couple revealed.

"Rob was furious when he found out about Pilot Jones and Chyna, and he vowed that he was never going to be blindsided by her again," the source told RadarOnline.com.

Kardashian has kept constant watch over his fiancée and baby in the days since her birth, and the source told RadarOnline.com that he has been monitoring who Chyna was communicating with as well. "Rob wanted to check Chyna's phone non-stop," the insider claimed. "He doesn't believe her when she says she is just texting friends about the baby." Indeed, just weeks before the baby was born, RadarOnline.com revealed that she had been texting with actor Pilot Jones while still dating Kardashian.

"Rob is insanely jealous of almost every single guy in Chyna's life," the source explained. "Business contacts, guys who are married ... He thinks that all of them have a chance with Chyna and he can't stop being suspicious. He tries to cut Chyna off from everyone but himself."

Meanwhile, the source said Chyna isn't helping to calm Kardashian's paranoia. "Chyna loves to mess with Rob. She knows she has the power in the relationship so she never is going to reveal what she is doing," the source said. "But he SHOULD be worried, because she always does whatever she wants."
