"That's a fun prediction! @TheNotoriousMMA you also predicted a donation to my foundation and you and your team stopped responding after the fight in January. See you soon. July 10th Paid In Full!" Poirier tweeted.

McGregor then responded: "A donation, not a debt. We’ve been awaiting the plans for the money that never came. I do with all my donations. Know where it’s going dot for dot. Otherwise it goes walking. As is the case with a lot of these foundations, sadly. You took the McG over the belt shows I was right."

Poirier said the Irishman’s team didn’t respond to their emails.

"100% never a debt. You offered, we accepted, and like I said your Team never responded to our emails regarding the process of where funds would be put to work! July 10th you will taste defeat yet Again," he said.

McGregor fired back and got expletive.

"My team does their due diligence to make sure every donation meets the mark. My generosity is known. You will pay with your brain for this attempt at smearing my name. Shooting a*s shelling a*s b---h. Little b---h kicks from a shell. Good luck when you’re caught. You’re f—ked."
