Jake Paul taunted Tommy Fury with a $1.2million ringwalk outfit which featured the Union Jack and a message to his rival.
The unbeaten fighter's white shorts - which Paul had boasted were the most expensive in boxing history - were adorned with silver and also contained Rolex watches on the waistband.
Paul also wore an oversized red, white and blue top to the ring to represent the Union Jack, containing a message to original opponent Fury.
The top read: "Hey Tommy, wish you could've been here but watching from a TV is cool too."
Unlike opponent Tyron Woodley, who entered with a pair of headphones clamped to his ears, Paul took the acclaim of the crowd having entered to the sound of the Village People's YMCA.
And the relaxed 22-year-old even acted out his ringwalk music once he had clambered through the ropes.
After a tight and cagey opening five rounds, Paul put his money where his mouth is by brutally knocking out Woodley with a vicious right hand.
Paul had defeated AnEson Gib, former UFC star Ben Askren and former basketball player Nate Robinson before taking on Woodley in August.
Paul emerged victorious by split decision and was due to take on Fury last night before the Brit pulled out injured.
Woodley stepped in at two weeks' notice in an attempt to avenge his defeat four months earlier.
Paul's shorts were not the first example of his wealth after he arrived at the pre-fight press-conference with a $500,000 custom-made belt branded as the 'Most Valuable Boxer' belt which featured diamond watches and a Hermes Birkin bag.
"This belt is for me, that's why it says 'for Jake Paul ' right here," Paul explained, confirming that it was a gift and not up for grabs on Saturday.
"This is the Most Valuable Boxer belt, designed by Alec Monopoly, we've got a diamond Rolex, diamond Cartier and an Hermes Birkin sowed into the side.
"It's for the most valuable boxer of this generation. I don't need nothing, I've already got everything."
The 25-year-old also wore a Richard Mille RM055 Bubba Watson watch which is expected to have a value of around $520,000.
But boxing star Gervonta Davis later trolled the rising star by claiming the watch was "fake".
Paul has earned several bumper paydays for his exploits in the ring including a guaranteed $2million for his opening match-up with Woodley according to the commission.
The YouTube star also earned £520,000 for his tilt against Askren where he produced a first-round stoppage before calling out Conor McGregor.

And Paul claims he could earn as much as $250m if he reaches 10-0 in the ring.
"I can make $250m from this sport, all I got to do is keep winning," he said on an episode of Showtime's All Access.
"I'd be an idiot to let this sleep through my hands, to fumble this bag and the bag I'm about to get. That's why I'm so f****** serious about this.
"If I'm sitting there as the little Jake, my dad's feeding us hamburger helper working for $10 an hour, now I have an opportunity to make $250 million?
"Little Jake would do anything in the world to get to that and that's what I'm doing now."
