In an interview with Access Hollywood promoting her role in Entourage, Rousey was asked whether she would get in the ring with the high-profile boxer. Her answer was loaded:
"Well, I would never say that I can't beat anyone, but I don't think me and him would ever fight," she said.
"Unless we ended up dating," she added with a laugh.
Mayweather, who successfully defended his championship belt against Pacquiao earlier this month, banned two female reporters from the fight due to their tendency to question the fighter about his domestic violence allegations.
"He has had a string of domestic violence arrests, citations, and in 2010 an incident that landed him in prison," said one of the reporters, CNN's Rachel Nichols, in a September interview.
"According to the police report, Mayweather grabbed the mother of his three children and, by the hair, punched her in the head several times, and threatened to kill her. This was all in front of his kids, who he also threatened to kill before one of them called the police."
When Nichols asked Mayweather about the incidents, he said, "everything has been allegations. Nothing has been proven, so that's life."
Rousey will appear in Entourage as herself when it hits theaters June 3.
