Blac Chyna is using her 2-year-old son King Cairo to get revenge on her ex/baby daddy Tyga, says Tyga.

Chyna and Tyga are reportedly on the verge of a full out custody war … and according to Tyga, it’s all over his relationship with Kylie Jenner.

Sources close to Tyga tell TMZ:

He doesn’t think his relationship with Kylie is any reflection on his ability to be a good dad … and no one — not even BC — can legitimately question his parenting skills

We’re told Tyga believes any attempt to wrestle custody away from him is simply because he chose KJ over BC.

Our sources say Tyga thinks if anyone is questionable it’s Blac Chyna, whom he claims cares more about twerking than raising their son.

Just weeks ago, Chyna leaked text messages of Tyga begging her to allow them to be a family again. These two may be messier than Amber Rose and Wiz Khalifa!
