A few months after police were called when a fight between Blac Chyna and her make-up artist got ugly, the 31-year-old reality TV star has found herself in trouble with the law again.

According to several reports, Blac Chyna allegedly threatened her hair stylist with a knife inside her San Fernando Valley home. Reports also suggest that she did this in front of her and ex Tyga’s six-year-old son, King Cairo, although nothing has been officially confirmed.

The hair stylist reported the incident to police after the argument – which was allegedly about Blac Chyna owing her some money – and they are said to be investigating further. No arrests have currently been made, according to LAPD.

Reports also claim that the hair stylist wasn’t completely innocent in the altercation either, as she allegedly hurled soda cans at Blac Chyna’s car after she left her house.

Yikes!

As King Cairo was said to be inside the house when everything kicked off, the L.A. County Department Of Children And Family Services will apparently be stepping in to complete a welfare check. There has been no official report on where Blac Chyna’s daughter Dream – who she shares with Rob Kardashian – was at the time.
