Blac Chyna is making headway in her ongoing heated custody battle with ex-fiancé Tyga over their 11-old son King Cairo.

The Rob and Chyna alum, 35, just completed a court-mandated parent education class, just after the Rack City rapper filed for sole custody of their son.

Court documents obtained by Page Six revealed that Blac Chyna, born Angele Reneé White, graduated from the “Our Children First” online course on November 1.

She had also deactivated her OnlyFans in March.

Blac Chyna and Tyga welcomed their son, King Cairo Stevenson, in October 2012 – a year after they met. They were even briefly engaged, but called it quits in 2014 over the rapper’s alleged affair with Kylie Jenner, who was 16 years old at the time.

The television personality, who then had a daughter with Rob Kardashian in 2016, first filed a custody case in July to establish paternity and collect child support from Tyga for their young son.

Tyga, whose real name is Michael Ray Stevenson, blasted his ex on the comments section of a Shade Room post revealing the news of Chyna’s lawsuit.

“10 years later… nah… stick to ur schedule sat-mon [sic],” he wrote.
