Check your mailbox, Dustin Poirier ... it's about to be filled with a pricey Conor McGregorchain -- 'cause Jake Paul says he sent out the trolling diamonds on Thursday evening!!!
Paul copped the piece ahead of last Saturday's McGregor vs. Poirier tilt ... and it was pretty funny -- making fun of Conor for being dazed after getting rocked by Dustin in their second fight back in Jan. 2021.
And, when Poirier beat McGregor again over the weekend, Paul offered DP the $100K bling as a congratulations gift -- and Diamond accepted!
