Blac Chyna looks like she has moved on to another rapper ... Playboi Carti.
Chyna shared video early this morning of her and Playboi Carti driving around Los Angeles -- filtering the video with hearts.
As we reported ... Playboi Carti was arrested back in July at LAX when he got in a heated dispute with his then girlfriend. The "Magnolia" rapper was arrested for domestic battery, but ended up not being charged.
Playboi -- we recommend you learn from Chyna's past flings and hold off on the ink.
