WATCH: The Irish fans are already in good voice ahead of tomorrow's big fight
We're getting excited and so are the fans in Las Vegas.
Only one more sleep to go until the biggest fight of the decade, everyone. Friday feels a lot like Christmas Eve, however, and we just don't know if we will be able to get any sleep tonight.
(Getting sleep tonight would be nice though considering we will definitely NOT be sleeping tomorrow).
If you are to compare this huge event to Christmas then these Irish fans, who have travelled half way across the world to cheer on the boy from Crumlin, have certainly got a fantastic present in their stocking.
One of McGregor's most 'notorious' phrases describes how the green, white and gold aren't here to take part but instead to take over and with the amount of colour on show in Las Vegas, it seems the takeover has already begun.
Mick Konstantin, the man behind the song There's Only One Conor McGregor is preparing himself for the biggest performance of his life tonight but he still managed to take some time out to have a good Irish sing-song with supporters.
Our favourite moment is when everyone raises their cans to the lyric "the Irish invasion you can't mistake us."
No, we can't mistake you and we wouldn't replace you for the world, Irish fans.
