Tyga warned his former lady-love Blac Chyna to stop “trash talking” his current girlfriend, Kylie Jenner, or he would cut off her income. The threat comes amid an ongoing feud between Jenner, who turned 18 on Monday, and Chyna, since Tyga and the teenager started dating.

“Kylie’s 18 now and Tyga’s has had enough of the games that Blac’s playing,” a source close to Tyga told Hollywood Life, adding: “Kylie means more to him than ever. She’s literally his rib, and their relationship is about to get turned up two notches. He’s not going to tolerate Blac trash talking his girl. That ain’t cool. He’s warning Blac to shut her trap ASAP! He’s already taken her G-Wagon back. He can go further. He can pull the rug from underneath Blac, as well as that weave from her hair. She would want to quit while she’s ahead before he revokes her seat on his gravy train.”

A report Tuesday cited an insider as saying that Jenner would like Chyna to “mind her own business” and focus on “getting a real career.” The source also said that Jenner believes Chyna, who has taken digs at the teenage reality TV star, should “stop mooching off Tyga for support.” Chyna has a two-year-old son, King Cairo, with Tyga.

Chyna is reportedly waiting to see the "Keeping Up with the Kardashians" star’s gift from Tyga -- a $320,000 Ferrari 482 Italia -- being taken away, as she believes that he cannot afford the car and that it could get repossessed.

“Blac Chyna’s not at all impressed with this Ferrari Tyga allegedly gave his little 18-year-old friend,” a source reportedly said Monday, adding that Chyna has “driven a bunch of exotic sports cars in her day.”

Speculation of a wedding announcement from Jenner and the "Rack City" rapper have been swirling around now that the "KUWTK" star has turned 18, and she has been spotted sporting a ring twice before.

The couple had broken up in April, after Chyna posted screenshots of her conversation with Tyga, who had allegedly asked to get back together with Chyna. Since then the feud between Jenner and Chyna has intensified with both ladies taking apparent shots at each other through photos on Instagram, without actually taking names.
