Floyd Mayweather has just been knocked out in the first round by UFC fighter Ronda Rousey.

The undefeated boxer and MMA star were both nominated for Best Fighter at the 2015 ESPY Awards, but it was Rousey who took home the award. It’s her acceptance speech on the red carpet that’s the real winner, though.

“I wonder how Floyd feels being beaten by a woman for once,” she says. “I’d like to see you pretend to not know who I am now.”

Mayweather has faced domestic violence charges in the past, most recently pleading guilty to misdemeanor battery in 2011 after his former girlfriend filed a police report. He also pled no contest to two counts of misdemeanor harassment connected to threats made against his children. Mayweather was sentenced to 90 days in jail.

In the past, the idea of Rousey and Mayweather fighting each other in a ring — or octagon — has been brought up, most notably by UFC President Dana White. Rousey put hopes of a confrontation to rest once and for all while promoting the “Entourage” movie, saying, “I don’t think me and him would ever fight unless we ended up dating.”
