Former five division world champion Floyd Mayweather put on the fireworks at his kick-off press conference to officially announce the exhibition fight with Youtube star Logan Paul.

Their Showtime pay-per-view fight will go down on June 6 in Miami, Florida.

During the Thursday media event, Mayweather went face to face with Logan's younger brother, Jake Paul - and their short war of words erupted in a full brawl.

Jake Paul swiped Mayweather's cap and ran away. He was chased down by Mayweather and his security team. There were a few punches thrown by both teams. Jake Paul, who a few hours later was sporting a black eye, claims a Mayweather security member punched him in the face.

“He told me he was going to do it [and] I told him not to,” Logan Paul told reporters.

After what happened to his brother, Logan Paul says the contest has become personal for him.

“F--- yeah, bro,” Logan Paul said. “This sh!t is so personal now. This sh!t is so f------- personal. I thought this sh!t was going to be kind of cute and we’d go out and put on a show. But it’s going to be a fight, bro. It’s going to be a f------ fight, bro. It’s going to be a f------ war.”

Logan Paul, even with his significant size and weight advantage, is a huge underdog in the fight.

Mayweather, at 44-years-old, is regarded as one of the greatest fighters of all-time.

Logan on the other hand, has a single pro fight on his record and lost a controversial six round split decision against Youtube rival KSI in 2019. Due to the COVID-19 pandemic, Logan was unable to move forward with any fights in 2020.
