Mark Wahlberg – who yesterday was named the highest paid actor of the last year – revealed that he is backing Conor McGregor in his upcoming fight against Floyd Mayweather.

He and superstar rapper Diddy recently did a promotional video for the fight, which takes place on Saturday night.

The promo makes reference to a previous bet the two made when Wahlberg picked Pacquiao for the 2015 Mayweather-Pacquiao showdown. It didn't work out so well for him, as he lost $100,000 to Diddy.

The new video sees them have some banter and agree to put down ‘double or nothing’ for the latest fight before heading themselves to face one another in a boxing ring.

"Let's do this before your bodyguards come," Wahlberg quips. "You know you're about to feel it, right?" He then exhibits his shamrock-adorned glove.
