Our man Sandro Di Michele is in Las Vegas. Check out his diary and video features after the fighters held their final press conference.
Wednesday marked the final press conference ahead of Saturday's blockbuster - and to be honest it was a little more subdued than what had preceded it on the World Tour.
That was until our team in Vegas caught Floyd Mayweather losing his cool, his temper, the whole shebang with a heckler. If you haven't seen it yet check out the pinned tweet on our twitter feed.
We started with WBC President Mauricio Sulaiman unveiling 'the money belt' for this fight. It's not the sort of thing you pick up in a rush at M&S - this one is made of alligator leather and has 3,360 diamonds, 600 sapphires, 300 emeralds and 1.5 kilograms of solid, 24-carat gold.
Just in case you want to know what it looks like...here you go.
We then had the fighters come in and Conor McGregor dealt with the hecklers in the Mayweather camp in his usual style - to say he wasn't flustered is something of an understatement.
You won't be surprised to hear there was a significant difference of opinion between the two protagonists.
Floyd made it clear that if you give it, you have to to take it and vowed Conor will find this out on Saturday.
McGregor, well he's already thinking beyond Vegas this weekend - in fact he's got his eye on creating a brand new sport in the immediate aftermath.
That may have to wait though - according to Floyd Mayweather Snr. You see he knows exactly how his son is going to win this fight on Saturday - and it's a 3/1 chance with Sky Bet.
