Blac Chyna Posts Rob Kardashian's Phone Number On Twitter — Find Out Why!

Just days after Rob Kardashian tweeted little sister Kylie Jenner’s phone number out to the world, fiancée Blac Chyna did the very same to him!

Chyna revealed her motives in a Snapchat video on Thursday, telling followers that she was preventing her baby daddy from texting other women.

“To ensure your man is not texting no b*itches, just tweet his number out,” she said, sitting next to Kardashian. “How’s that feel Rob?”

“Feels good,” he smiled in return as his phone blew up.

“Get your number changed! Thank you,” Chyna responded gleefully.

Meanwhile, things have not been going well for the couple since filming began for their show, Rob & Chyna, with Kardashian slipping back into his troublesome old ways.

As RadarOnline.com exclusively reported, Chyna is not going to let the reality star continue on his downward spiral, even threatening to limit his time with their daughter if he doesn't get help.

A source close to the couple told RadarOnline.com that Blac is giving her baby daddy an ultimatum to "straighten up," or else she will take drastic measures to keep him from their child.

"A lot of people around Rob want him to go to rehab before the baby is born," the source told RadarOnline.com. Kris Jenner's only son sought help for his issues previously, but sunk into a deep depression again during his fiancée's pregnancy.
