Kenya Barris has filed a restraining order request for protection from his own sister. The Black-ish creator claims his sister, Colette Barris, used his fame to score her own Hollywood deals for years.

But Colette, a teacher and author, failed to make any progress on her own projects, which Kenya has always refused to help her with. Now Kenya is concerned that his sister will take out her anger on his six children.

According to court papers obtained by TMZ, the famed writer and producer is now seeking legal protection to force Colette to cease communication with him and leave his family alone.

In the filing, Kenya describes their dysfunctional relationship and alleges the last straw came when Colette insisted he had to fund a $4 million adaptation of one of her books - or else, she'd go public with his dirty laundry.

Colette has yet to respond to the allegations, and a ruling on the restraining order request has yet to be made.
