Post Malone is making good on his $20,000 bet with YG ... finally paying up 9 months after his beloved Dallas Cowboys lost to the L.A. Rams in the NFL playoffs.
Posty had his manager, Dre London, personally deliver the cash to YG in a manila envelope Monday in Los Angeles. The handoff went down on the set of Tyla Yaweh's music video shoot for his collab with YG, "I Think I Luv Her."
As you know ... Post Malone is a huge Cowboys fan, and he put a ton of action on their playoff game, back in January, against the Rams.
