Hands up if you've been keeping up with Khabib Nurmagomedov and Floyd Mayweather's back and fourth on Instagram about a potential fight.
It's a spectacle all UFC and boxing fans would love to see, regardless of whether it takes place in the Octagon or the boxing ring.
Khabib got the ball rolling by calling out Mayweather following his victory over Conor McGregor at UFC 229 by saying 'there is only one king in the jungle'.
"Let's go Floyd," said Khabib in a video alongside Leonard Ellerbe, CEO of Mayweather Promotions. "We have to fight now.
"We are two guys who never lose, 50-0 versus 27-0. [But] in the jungle there is only one king. Of course, I am the king because he cannot drop McGregor but I drop him easily. Let's go."
Mayweather soon replied by calling on America's major broadcasters, like CBS and Showtime, to get out their chequebooks and make the fight happen in Las Vegas.
However, Khabib has since made it very clear that he doesn't want to meet in Nevada by writing on Instagram: "But no Vegas, they won't pay my money."
Khabib still hasn't been paid for his win over McGregor due to the violent scenes that followed their fight at the T-Mobile Arena.
The Nevada State Athletic Commission (NCAS) are currently withholding the $2m purse.
American news website TMZ caught up with Mayweather in Beverley Hills on Wednesday and asked the 41-year-old about a possible match with Khabib.
Mayweather said that he wants to make the fight happen but on the one condition that it's in boxing, not UFC, considering Khabib was the one who called him out.
"Oh, we fighting!" said Money. "I'm my own boss, so I can't say what's going on on Khabib's end, but on my end we can make it happen.
"He called me out, so he's got to come to my world."
Mayweather also responded to Khabib saying that he couldn't drop McGregor when they met in the boxing ring last summer: "So Khabib, you got my leftovers. Whoopy-do."
It's expected that a boxing match between the two would earn Mayweather a nine-figure sum even higher than the amount he made after beating McGregor.
The American would also be putting his unbeaten record of 50-0 on the line by fighting Khabib, who is 11 years his junior.
