AceShowbiz - Blac Chyna's private gathering in her hotel suite ended in disaster late last month. The music video vixen-turned-reality TV star is reportedly facing a police investigation after one of the female guests left the room in tears following an incident with the star.

The woman along with several others were invited to Chyna's room after a Black Friday party that the brunette star hosted in town. According to the woman's friend, Chyna suddenly flipped out, started to cuss out the woman, and threatened the group.

"Everyone was enjoying themselves; the drinks were flowing and the energy in the suite was real good," so the witness told The Sun. "Suddenly out of nowhere Chyna just yelled at my friend to 'shut the f*** up' or she'd beat both our a**es."

The group decided to leave, but they're missing one person. "The vibe immediately changed so at that point we thought it was best to leave - but when I went to walk out she shut the door behind me and kept my friend in the room," the witness claimed.

Chyna allegedly refused to let the woman go until 20 minutes later when her entourage knocked on the door. When the door was finally opened, the woman burst out the room sobbing.

Details of what happened were unclear, but the female guest kept saying sorry while her friend insisted it was not her fault and blamed Chyna's "craziness" on drugs. When they were inside the elevator, the woman called out Chyna for being "mean" and "rude."

Blac Chyna hasn't made any comments on the drama. She recently attended a press event for the upcoming Uplive WorldStage Global Singing Competition.

The star, who's currently at war with the Kardashians following her bitter split from Rob Kardashian, offered advice to Khloe amid baby daddy Tristan Thompson's latest baby drama.

"Keep the baby first, then that's it. That's the most important part," she said. "Make sure the kids are good and that's it."
