Colby Covington mocked rapper Drake who lost $275,000 after backing Jorge Masvidal to beat his bitter rival.
Covington dominated his welterweight foe in Las Vegas last night to put an end to their white-hot feud.
But Drake was left out of pocket after backing Masvidal with the six-figure sum.
he odds for Drake's specific bet were unclear, but Covington started a general 2/7 favourite with Masvidal the 5/2 underdog.
Given those odds, Drake would have earned close to $1million from his original bet had Masvidal pulled off the upset.
Instead he was left empty-handed, and Covington didn't waste the opportunity to have his say.
"Let's talk about all the money that Drake lost tonight," he mocked. "He needs to go back to selling those s***** albums to get back the money.
"He should have went to America's pick of the week by my bookie. I tried to give the people the pick of the week. I'm America's champ and I was America's pick of the week. Drake, you suck at sports betting. Go back to your s***** little albums of rapping."
Covington admitted. he hadn't been at his best against Masvial and that he allowed their backstory to affect him.
He and Masvidal were best friends and teammates before a bitter falling out set them on a collision course in the cage.

And Covington added: "It wasn’t my best performance. Just a lot of emotions going into it.
"That was a real friend of mine at one point in my career. He’s just such a backstabbing thief, and he talks so reckless, and he’s tried to make some false narratives to the media, make a lot of lies like he does.
"He’s a liar. He’s a thief. I let the emotions get the best of me, but it was still dominant. I just showed how good I was, that I am the No. 1 fighter in the world for a reason, and it wasn’t even competitive tonight."
