Blac Chyna allegedly threatens stylist with knife

Blac Chyna and her hairdresser got into it early today, and it allegedly ended with Chyna pulling a knife on the stylist who then hurled soda cans at Chyna's car.

Chyna and her stylist were at her San Fernando Valley home when things got heated over money Chyna alleged owed the hairdresser.

The hairdresser filed a police report, claiming Chyna threatened her with a knife when the stylist asked for payment. Chyna sources deny she pulled a knife, but claim the hairdresser left in a huff and threw soda cans at Chyna's car.

Chyna's 6-year-old child, King, whom she shares with Tyga, was present during the fight and now that a police report has been filed,  theL.A. County Dept. of Children and Family Services will get involved and at the very least do a welfare check.
