Ronda Rousey is keenly aware of boxing pound-for-pound king Floyd Mayweather's credentials. It seems that Mayweather is not as familiar with hers -- or her gender, for that matter.
Asked in an interview with BoxingScene.com for his thoughts on Rousey, the bombshell mixed-martial arts star and the first and current UFC women's bantamweight champion, a confused Mayweather came up empty.
"I actually ... I don't even know who he is," Mayweather said.
Rousey made headlines recently with her assertion that she could beat Mayweather in an MMA-style street fight. She was backed up by UFC president and promoter Dana White, who told USA Today, "you take a street fight, Ronda wins that fight and hurts him badly."
Rousey began her career as a judoka, competing at the 2004 Athens Olympic Games and becoming the first-ever American woman to win an Olympic judo medal when she captured bronze in Beijing. She's since parlayed that into a successful MMA career that's seen her go undefeated en route to capturing the aforementioned championship, as well as a successful media career, including appearances in ESPN The Magazine's 2012 body issue, Maxim's 2013 hot 100 and appearances in the upcoming films Fast & Furious 7 and The Expendables 3.
Mayweather won a bronze medal in boxing at the 1996 Atlanta Games and has compiled a perfect 46-0 career mark while capturing world titles across five different weight classes over the course of his 18-year professional career. He'll next get in the ring on Sept. 13 in a rematch with Marcos Maidana, whom Mayweather defeated via majority decision in a highly contested bout in May.
