Logan Paul is annoyed that the Internet believes the brawl between his brother, Jake Paul (right), and all-time Boxing Hall of Fame inductee Floyd "Money" Mayweather (left), was fake.

Logan insists the fisticuffs was NOT a scripted stunt to promote his and Floyd's upcoming exhibition match that headlines a SHOWTIME PPV event on Sunday, June 6.

"I f**king wish that wasn't real," Logan (right) tells TMZ Sports. "I wish it was staged," Logan added, "That s**t is not funny. It's not fun for anyone."

Logan, aka "The Maverick, met face-to-face with Floyd on Thursday at a media event to preview their special exhibition match at the Hard Rock Stadium in Miami Gardens, Florida.

Jake stole the spotlight from his brother and got right in Floyd's face, then snatched Floyd's cap and fled -- with Floyd in hot pursuit.

"It's one thing to sell a fight, and people can say what they want, but one thing no one is going to do, is disrespect me," said Floyd.

"Floyd came out of retirement, just to get re-retired," said Logan. "I'm about to beat the greatest fighter of all time!"

Floyd was PISSED -- chasing after Jake while screaming that he was going to "kill" the YouTube superstar.

TMZ spoke with 26-year-old Logan after the violent incident involving his younger brother, Jake, 24.

Logan told the gossip outlet the incident gave him even MORE motivation to destroy Floyd when they step in the ring on June 6.

"That s**t just got personal by default. It was supposed to be like a cute little press conference... come together, get people excited for the fight. Not people talking about killing people! What the f**k!?"

When asked if he had a message for Floyd, he responded, "This is gonna be the craziest f**king evening to ever take place in the history of combat sports."

"My message to Floyd is this ... we're gonna get you that hat back, Floyd."

Thursday's event also included former NFL star wide receiver Chad "Ochocinco" Johnson, who will be making his boxing debut in an exhibition match against an opponent to be announced on the pay-per-view undercard.
