“Stimulated” rapper Tyga and his rumored fiancée Kylie Jenner went out for a ride Sunday in her Ferrari 458 convertible that he gifted to her on her 18th birthday, after throwing shade at his former partner Blac Chyna on Instagram. The posts on Tyga’s Instagram page seemed to be hitting back hard at rumors that he leased out the car he gifted to Kylie 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.

Soon after Tyga posted the message, Chyna’s best friend Amber Rose seemed to be replying to his comment through a post Sunday, saying: "She don't need a Ferrari she can Drive mine #BFFGoals."

Tyga posted another picture following Rose’s comment saying: "We drive our own whips peanut head #GoldPhantoms #LastKings."

On Sunday, he and Jenner were seen at a gas station in the Los Angeles neighborhood of Calabasas in Jenner’s new car. Tyga filled gas while Jenner was spotted ducking down inside the vehicle. The couple was later spotted buying groceries, according to the Daily Mail.

Rumors swirled Friday that Tyga had gifted Jenner a special diamond ring, suggesting that the two are officially engaged, Hollywood Life reported, citing an insider. “He gave her that ring and asked her to marry him,” the source said, according to Hollywood Life, adding: “Tyga and Kylie are engaged." However, the source added that the couple is not ready to break the news of the engagement just yet.

Chyna, who has a two-year-old son with Tyga, has been feuding with Jenner ever since she started dating her former lover.
