When UFC heavyweight Alex Pereira stepped on stage at the recent White House press conference, he wasn't just making headlines for his upcoming fight—he was turning heads for a completely different reason. Sean O'Malley, who's set to fight Aiemann Zahabi on the same card, couldn't believe his eyes when he saw Pereira's new physique.

"I've never seen a guy that looks like he got a BBL," O'Malley exclaimed, referencing the Brazilian butt lift trend. "Alex Pereira's ass is bigger than a Miami b—ch's BBL. I was in shock. Wait till you guys see it."

For context, Pereira's journey to heavyweight is nothing short of remarkable. The Brazilian champion first made waves at 185 pounds, where cutting weight was already a challenge. Since moving up to light heavyweight, he's dominated, never being outsized or outmuscled—even as he captured titles in two weight classes. Now, as he prepares for his heavyweight debut against Ciryl Gane, it seems he's packing on serious mass.

"He's gotta be 250," O'Malley estimated. "Whatever the f—k his coach is eating, they're eating." The bantamweight star admitted he couldn't look away: "I looked at his butt for like 7 seconds. Holy s—t, that was mind-blowing."

The matchup against Gane promises to be fascinating. While Gane will have a slight reach advantage, both fighters match up in height. The big question: How will Pereira's legendary power and speed translate to the heavyweight division? It's one of the most intriguing storylines heading into UFC White House.

And for fans watching at home? You might want to keep an eye on more than just the fists flying. As O'Malley put it, "No Diddy, wait till you see that wagon."
