The license plates on both cars matched and Tyga had recently asked Blac to give him the car back, so all evidence pointed to a re-gift.
A Kardashian source tells TMZ, however, that the G-Wagon wasn't actually a gift, Kylie just happened to be driving it that night. Tyga DID give Kylie a Ferrari 458 convertible on Sunday night, so nobody was really sure why Kylie was driving the G-Wagon.
As far as Blac Chyna is concerned, she wants to see receipts to prove that Tyga didn't give Kylie her old car. When TMZ caught up with her last night and asked her what she thought of the whole situation, she said, "All I'm sayin' is this...I want to see receipts. Show me receipts and we can talk."
Speaking of receipts, Blac has her own! When the model was asked to give Tyga back the G-Wagon, she went and bought this sweet ride and says she paid for it all in cash.
