Blac Chyna believes that Tyga is trying to use their son King Cairo for his benefit in case he fails to do “well with his career.” Chyna, who has been feuding with Tyga's girlfriend Kylie Jenner since they started dating, has now struck war with her ex-boyfriend.

"Blac Chyna was super p----- off after seeing the modeling photos of her son," a source told Radar Online. "Tyga did not confer with her about doing this and she does not want her son to be a public figure like the Kardashians."

Chyna and Tyga’s 2-year-old son made his modeling debut Wednesday for L.A. Gear’s kids' collection.

"She (Chyna) wants King to have a normal life and not be forced into fame, but Tyga is doing everything that he can to make sure King is famous," the source reportedly said. “Blac Chyna thinks that Tyga is trying to use her boy as a meal ticket if things do not go well with his career.”

King Cairo has previously appeared on several episodes of his father's MTV reality show, "Kingin' With Tyga."

"Tyga apparently wants to get King Cairo into music, more modeling, commercials and television shows and he knows that now is the time," the source reportedly said.

The "Stimulated" rapper slammed Chyna after rumors that he leased out the car he gifted to Jenner because he didn’t have money.

Tyga had posted a photo of himself on his Instagram page Saturday, captioning it “When the hating don't work they start telling lies. #WhereYoFerrariTho?" The message seemed like he was lashing out at Chyna, who he believed was one of the people starting the rumors, TMZ reported Sunday.

Chyna and Jenner have been in an Instagram war for months, with both women posting photos showing off their bodies in order to gain Tyga's attention. Chyna was also accused of using her son, King Cairo, to get Tyga back in her life.
