Dana White has threatened Jake Paul of legal action if he continues to approach his UFC fighters.
The president of the MMA promotion company is getting fed up with the YouTube star calling numerous stars out, including Conor McGregor, for a lucrative showdown on Triller.
Paul continued to create chaos amongst the boxing world by knocking out former MMA welterweight champion Ben Askren inside the opening round last weekend.
It follows up his ridiculous fight against NBA's Nate Robinson on Mike Tyson's comeback bout, which left the latter requiring oxygen.
"Honestly, when it comes down to signing the contract, these guys duck. Honestly, we'll see," Paul said in post-match interview about fighting McGregor.
"The McGregor fight just became more realistic, like I've been saying. I just want to do big fights."
White has warned there could be trouble in paradise if Paul continues calling out his UFC stable, which includes Nate Diaz.
"Why don't you go fight a f****** boxer? What the f*** do these guys keep talking to UFC guys for?
"I'm gonna have to slap them with another f****** legal letter, these f****** idiots. Go talk to f****** boxers. What are you doing?," White told Yahoo Sports.
White believes boxing is in a bad place and if they continue to stage events with YouTubers then it could get much worse.
"Boxing continues to go like this [points his hands downward]. This guy [Jake Paul] is playing this thing perfectly and boxing's in such a bad place.
"They're doing a really good job at sucking in people to buy into this thing. Good for him."
White did, however, deny a recent claim about betting Snoop Dogg $2million on the outcome of Paul vs Askren.
"I don't even want to say it. I don't even want to say what I think happened in that fight. But I can tell you this, I don't owe Snoop [Dogg] $2 million," White told TSN.
"I never bet - let me make it clear right here to everybody: I have never made an illegal bet, ever. I did not make an illegal bet on Saturday night. I did not bet $2 million with Snoop or anybody."
