Conor McGregor is currently gearing up for his highly anticipated title fight against Khabib Nurmagomedov at UFC 229 on October 6, but the Irish superstar is somehow still engaged in a war of words with Floyd Mayweather. 

Earlier this week, TMZ Sports caught up with the undefeated boxing champ to get his take on the upcoming UFC fight - and Mayweather had nothing but positive things to say about McGregor. "Conor McGregor, he’s a tough competitor, like I said before Conor McGregor’s not gonna back down from anyone, he’s not scared, he’s a warrior,” Mayweather said, before inviting McGregor to work out at Mayweather Boxing Club.

However, shortly after Mayweather's comments surfaced, McGregor took to twitter with the following message: “Fuck the Mayweathers, except Senior and Roger,” McGregor tweeted on Tuesday night. “There is no peace here kid. Step up or step down.”

Naturally, Mayweather responded in kind, by posting a photo of their August 2017 boxing match along with the caption: "Easiest 9 figures I ever made! All work is what ?"

Check out the back-and-forth in the tweets embedded below.

While Mayweather is the most recent target of McGregor's tweets of fury, he's not the only one in the Irishman's crosshairs. Last Friday, McGregor took it upon himself to fire the first shot at his upcoming opponent - and he didn't waste time bringing Nurmagomedov's father into the mud. The caption on McGregor's instagram post reads, "@abdulmanap.nurmagomedov I can see you. Cowering behind fake respect. Just like your middle child. A quivering coward."

McGregor and Nurmagomedov will square off at UFC 229 at the T-Mobile Arena in Paradise, Nevada, on October 6. Check out the first jab from McGregor in the IG post embedded below.
