Jake Paul also got in on the Dakota Dycheva craze.
The YouTuber-turned-boxer, who is currently under contract to compete in mixed martial arts with the PFL, was on hand to watch UFC's biggest rivals put on an epic event on Thursday night.
While the undercard bout, which featured a bizarre double knockdown, made headlines, it was Ditcheva's latest win that truly impressed many MMA fans.
Paul praised the Manchester fighter on X (formerly Twitter) following his first-round knockout at PFL 4 in Uncasville, Connecticut.
“The next MMA superstar… Dakota Dycheba,” he tweeted alongside footage of the end of the fight.
Ditcheva pushed her opponent, Chelsea Hackett, against the fence and forced her into a clinch position, then landed a series of knee strikes that staggered the Australian fighter.
Paul's new favourite fighter then got out of the clinch and began to let go as Hackett, known for his kickboxing prowess, looked confused.
A perfect body shot finally put an end to the one-sided assault.
Ditcheva recorded her seventh consecutive stoppage win and three consecutive first-round finishes to improve her unbeaten record to 12-0.
The PFL uses a seasonal format, with fighters accumulating points based on wins and placements to qualify for a knockout stage later in the year.
The 25-year-old won 12 points to advance as the top seed, but will face an even tougher test in the semi-finals when she takes on Jenna Bishop.
Former UFC fighters Talia Santos and Liz Carmouche will face either Ditcheva or Bishop for a chance to win a $1 million flyweight tournament in November.
That's the same month that Paul is scheduled to fight Mike Tyson.
“The Problem Child” was scheduled to welcome Tyson to the ring on July 20, but recent health scares have forced the 57-year-old to withdraw from the bout.
Event organizers quickly set a new date for November 18, breathing new life into the controversial battle between two men with a 31-year age difference.
Perhaps after they fight, Paul will make his long-awaited MMA debut and join Ditcheba as an active PFL fighter, 18 months after announcing his move to the sport.
