UFC boss Dana White reveals the rudest celebrity he's ever met

UFC CEO Dana White let it rip on who he thought was 'the rudest celebrity' he’s ever had the misfortune of encountering.

Speaking on a recent episode of The Katie Miller Podcast, the brash and controversial driving force behind the Ultimate Fighting Championship said Sean 'Diddy' Combs was the one he wanted to 'stick it to.'

Initially, White, 56, had to give it some thought after Miller posed the burning question.

'Good question, what a great question,' he began. 'Let me really think about this so I can really f***ing stick it to whoever it was.

'Who did we run into that’s --,' he started to ask someone off camera. The person answered: 'Diddy.'

'Oh, Diddy, 100 percent the biggest douchebag ever,' agreed White, who needed an interpreter to translate a question from a British journalist during a recent press conference.

He went on to tell a story about how Diddy and his security team 'scared' his niece, who used to be fan but probably isn't one now.

'Tony Hawk used to have these charity events,' White added, referencing the professional skateboarder. 'And when my kids were little, you'd go to these charity events and, like, lots of celebrities would be there. So everybody would do things for each other's kids,' White described.

'So I had my niece at one of them, and Diddy shows up and, it was at Ron Burkle's house. My niece was, like, all excited, like, "Oh, my God, P Diddy is here." I said, "Awesome. Go take a picture with them. And she comes back. "Did you get a picture?" And she’s like, "No, they were scary."

'The guy's there with f***ing 10 security guards, right? You need security at a f***ing kids event? And then they were rude to her and scared her. That’s who's listening to your f***ing s****y music, okay? That's who’s listening to this, okay? Are you f***ing kidding me? And that's how you’re going to treat some girl that's a fan and wanted a picture with you?'

White added: 'And Conor McGregor was a P Diddy fan. Conor ran into him. It's the USC game. He wanted to punch him in the face when he met him.'

Diddy, 56, is currently serving a 50-month federal prison sentence in New Jersey for convictions on two counts of transportation for the purpose of prostitution.

The rapper was acquitted of more serious charges of sex trafficking and racketeering in July 2025, and his lawyers are appealing the sentence.

Meanwhile, White sparked a major fury after describing the shooting at the White House Correspondents’ Dinner as 'f***ing awesome.'

The MMA mogul was seated near the head table at the Washington Hilton on April 25 when a heavily armed gunman ran through a security checkpoint, leading to an immediate evacuation of President Donald Trump.

White admitted he refused to follow the instructions of Secret Service agents to get down, even though a majority of the 2,000 guests – including cabinet members and journalists – dived for cover.

Describing his immediate reaction, White told USA Today: 'It started to get noisy. Tables getting flipped over, guys running in with guns.

'They were telling me to get down, I didn't get down. It was f***ing awesome. I literally took every minute of it in. And it was pretty crazy, unique experience.

'We were sitting right in front of where the President was. Nobody got tackled. Guys came in looking for shooters. They came over to our table. I thought the shooter was over by us or something.'

White's reaction to the terrifying incident drew some backlash from social media users.

One took to X to write: 'Pretty weird reaction if we're being honest.'

'What a clown,' another said on the social media platform.

'WTF is wrong with him. He seems insane,' a third vented.

White was present at the event as a guest of the President and was seated at a table with representatives from Paramount Skydance, the broadcast partners of the UFC.

White and Trump have built a strong relationship in recent years, with the President regularly appearing at UFC events across the country next to the outspoken businessman.

And White has frequently spoken on Trump's behalf at political rallies and national conventions.
