The Floyd Mayweather vs. Conor McGregor bout is now just days away, with months and months of hype being distilled into one incredibly anticipated Pay Per View sporting event. 


Back in May 2015, rapper Sean "Diddy" Combs and actor Mark Wahlberg made a viral $250,000 bet on the outcome of the Floyd Mayweather Jr. vs. Manny Pacquiao fight, and now the two boxing fans are putting their friendly rivalry into the boxing ring.

In a promotion for the upcoming Mayweather vs. Conor McGregor fight that airs Aug. 26, Diddy and Wahlberg are betting "double or nothing" in the fight "Diddy vs. Wahlberg."

In an over-dramatized clip of the fight, Wahlberg and Diddy banter before entering the ring. "Let's do this before your bodyguards come," Wahlberg quips. "You know you're about to feel it, right?"
