"She was punching him in his back and arms and was in a drunken rage," a source said.
Reportedly, she didn't stop battering Rob until Kris Jenner's boyfriend, Corey Gamble, walked in on their fight and pulled her off of him.
E! News points out that this may not be Chyna's first time getting physical with her paramours, pointing to one of the leaked text messages where she wrote, "I don't wanna treat [Rob] like Tyga but I will. Imma slap the s**t outta him."
Yikes. Maybe it's best that these two spend some time apart. According to E! News' source, Rob especially should be careful of Chyna, saying, "He's a victim and she's using him."
The source added that Rob's sisters are "fed up" with all the drama and Chyna's behavior specifically, so much so that she's not welcome at their annual Christmas Eve party.
"The sisters don't want anything to do with this relationship," the source continued. "They see how fake it is. It's so unhealthy for their brother. They see how Chyna is using their family for fame and money and they aren't going to let it happen anymore. The family accepted her but since Chyna is now showing who she really is, they don't want anything to do with her. They have real-life problems going on and are trying to have a positive New Year and not this drama."
This is sad all around. Here's hoping Chyna and Rob can get themselves together, for the baby's sake, if nothing else.
