Let the trash talk, hot takes and continuous hype begin. The showdown between Floyd Mayweather Jr. and Conor McGregor is officially happening.

The two will square off in a boxing match on August 26 in Las Vegas.

Mayweather--who holds a 49-0 record as a boxer--is an overwhelming favorite over the MMA Champ.

McGregor is the first UFC fighter to claim two titles in two different divisions, but is making his boxing debut against his undefeated opponent.

The smack talk has already begun between the two.

McGregor took a jab on Twitter at the age of his 40-year-old opponent by using a picture of his father, Floyd Mayweather Sr.

Over the next two months, expect the two to engage in a lot more than simple twitter talk to get people ready for the fight.

But for now, it's still amazing that this thing is actually happening.
