TMZ also reported he alleged that Chyna “snorts cocaine,” is always drunk and spends “$600 on alcohol” daily. Khloé reportedly made a statement in the filing, claiming that Dream has been “decidedly more aggressive” lately and says she doesn’t want to go home to Chyna, TMZ reported. PEOPLE has not independently reviewed the alleged court filings, and a representative for Chyna has not responded to PEOPLE’s request for comment. According to the outlet, in the sealed court papers, Rob accuses Chyna of being violent, citing one occasion where she allegedly threw “sharp objects” at her hairdresser. Rob also claims that Chyna’s alleged partying ways have affected Dream’s behavior, as the child now allegedly uses foul language and is violent with other children, the website reports. Rob is seeking to have Chyna’s parenting time reduced to just weekends with a nanny present, according to the filing obtained by TMZ.

In July 2017, Chyna accused the reality star of violating California’s revenge porn laws by posting graphic and expletive-ridden content about her — including three naked photos — while accusing her of drug/alcohol abuse and infidelity. Chyna also claimed in court documents obtained by PEOPLE that he allegedly hit her and threatened to kill himself multiple times.
