Rob Kardashian Orders New DNA Test Amid Explosive Paternity Showdown With Blac

All hell has broken loose between Blac Chyna and Rob Kardashian — and now he’s ordered a second DNA test to prove if Dream’s his daughter or not!

“He’s got it in his head that Chyna faked the first paternity test,” revealed a family insider.

“She’s said to him many times in anger that Dream’s not his baby and even though she always backtracks later, saying she was trying to hurt him, Rob’s literally been having nightmares about it.”

As RadarOnline.com reported, Kardashian, 30, and 28-year-old Blac have been battling a nearly constant tug-of-war over the state of their off-again, on-again relationship.

Unfortunately, 5-month-old Dream is now dead center in her parents’ continuing drama.

“Blac’s really messed his head up big time and he’s not thinking straight,” explained the insider.

“Deep down he knows Dream’s his baby — she’s the spitting image of him and his name’s on the birth certificate — but it’s Blac he doesn’t trust.”
