Blac Chyna is fighting for full custody of King Cairo

Oh dear, we can see this turning quite bitter.

TMZ have reported that Blac Chyna is fighting for full custody of her and Tyga's son, King Cairo.

She hired a top divorce lawyer last week and wants primary custody of their 2-year-old son. 

She is not keen on the idea of her son going back and forth between different homes because he is starting preschool soon, sources close to Blac Chyna have told TMZ.

However, there are more issues surrounding the situation and Tyga's girlfriend, Kylie Jenner, has a lot to do with it. 

She thinks the fact that 25-year-old Tyga is dating a minor reflects his parenting skills and she doesn't want Kylie around her son too much either because she believes the Keeping Up With The Kardashians star lacks maturity. 

She only wants Tyga to have weekend visitation. Things have certainly changed since Tyga wanted full custody after their split. He eventually settled for joint custody. 

She also wants child support to cover housing expenses, food, clothing, school and nannies.

Things have turned bitter between the pair due to Blac Chyna's disapproval of Tyga's relationship with Kylie.
