The stars were out in force at UFC 295 on Saturday night.
One of those cageside in Madison Square Garden was WWE United States champion Logan Paul, who gave a shout out to Dominik Mysterio despite spelling his name wrong.
Paul recently fought Dominik's father, Rey Mysterio, earlier this month at WWE's Crown Jewel event in Saudi Arabia for the WWE United States title.
Paul would go onto claim his first WWE title after using brass knuckles to catch Mysterio off guard when he was about to complete his iconic 619 finishing move.
