Blac Chyna -- Show Me Proof Tyga Didn't Give Kylie My Hand-Me-Down (VIDEO)

Blac Chyna got the last laugh in the Mercedes G-Wagon debacle, jumping into her new ride and vaguely casting doubt on what really happened with her vehicular hand-me-down.

Chyna was leaving Playhouse in Hollywood Saturday night, when we asked about our story that Tyga demanded she return the G-Wagon he got her when they were together. He painted it red and the next thing we knew Kylie Jenner was behind the wheel ... and it sure looked like a re-gift.

Tyga's people insisted he did not give the G-Wagon to Kylie ... she just happened to be driving it to her birthday dinner.
