It's safe to say Blac Chyna isn't a fan of her baby daddy Tyga's relationship with 17-year-old Kylie Jenner — but the model is taking their ongoing feud to the next level by reportedly fighting for full custody of their two-year-old son, King Cairo, as a form of revenge.

According to TMZ, the 27-year-old model hired a top divorce lawyer and plans to limit the amount of time Tyga, 25, gets to see his son. With King getting ready to start preschool in the fall, she reportedly wants him to have a regular schedule like the rest of the kids his age.

Sources close to Blac also claim she believes that his relationship with the underage reality star "shows bad judgment that translates into his parenting skills." They claim she doesn't want Kylie around their child because she "lacks maturity."

The outlet also reports that Tyga initially wanted full custody, but decided not to follow through. Now, Blac is allegedly hoping to get it — as well as child support to cover "housing expenses, food, clothing, nannies and school."

An insider tells Hollywood Life that his relationship with Kylie is definitely adding fuel to the fire.

“She feels humiliated that he chose Kylie over her. That’s devastating and something she’s going to struggle with for a very long time,” the source told the outlet. "Every time she calls him out on social media, it’s because she’s hurting inside and wants him to feel her pain.”
