The feud between Blac Chyna and Tyga rages on. The model reportedly wants custody of her child with the rapper because she’s jealous of the 25-year-old’s relationship with Kylie Jenner.

TMZ reported that Black Chyna is seeking sole custody of the former couple’s son, King Cairo, on Tuesday, though she would allow Tyga weekend visitation rights. Blac Chyna reportedly felt that Tyga’s involvement with a minor shows “bad judgment that translates into his parenting skills.” She also felt that Kylie was immature and she didn’t want that type of influence around her son.

A source close to Tyga told TMZ on Wednesday that he didn’t feel that the rapper’s relationship with teenage Kylie had anything to do with his parenting skills, and that no one should question his ability to be a good father. The source also said that Blac Chyna’s simply jealous that Tyga chose the youngest member of the Jenner/Kardashian clan over her.

Black Chyna’s dislike for 17-year-old Kylie is no secret. The 26-year-old has openly dissed Kylie Jenner before by mocking her on social media.

The model posted a photo of herself with fake wax lips on April 21 when thousands were participating in the Kylie Jenner lip challenge. Though she didn’t include a caption with the photo, fans assumed it was taken in response to the online trend, where participants placed a glass or plastic cup around their lips and sucked on it for five minutes, resulting in a swollen, but bruised pucker.

Blac Chyna also posted alleged texts she’d received from Tyga on April 23, telling her that he wanted to be a family again and raise the couple’ child together, according to Hollywood Life. Kylie and Tyga reportedly split after the incident, but got back together shortly after.
