Is Ronda Rousey's next fight against Floyd Mayweather Jr.? The 28-year-old UFC Women's Bantamweight Champ is reportedly challenging the 38-year-old boxing champ in a rule-less fight, where Rousey believed she could beat Pretty Boy.

Ronda Rousey and Floyd Mayweather Jr., two of the world's greatest fighters, have been involved in a highly-publicized and bitter feud. Though Rowdy is a woman, she isn't the type to back down from any fight challenges.

On Monday night, Ronda Rousey delighted all her fans in her no-holds-barred Q&A session in Reddit's "Ask Me Anything" chat. According to ESPN, Rowdy told one of her fans that she could beat anyone on this planet and not just Mayweather.

"Floyd is one of the best boxers of all time," Rousey said. "He would definitely beat me in a boxing match. I unfortunately don't get into 'matches.' I fight for a living. In a no-rules fight, I believe I can beat anyone on this planet. Boxing is a sweet science with strict rules that I respect very much and aspire every day to improve at. But you said ruleless fight, and that's my honest answer."

Just a month ago, Ronda Rousey already defeated Floyd Mayweather Jr. for the "Best Fighter" award at the ESPYs. The Huffington Post noted that after her win, she made some comments about his long and well-documented history of domestic violence.

"I wonder how Floyd feels being beat by a woman for once," she said after the win. "I'd like for him to pretend to not know who I am now."

Meanwhile, Ronda Rousey was also asked about the possibility of facing fellow MMA fighter Cris Cyborg.

"She's just waiting to be offered enough money to get her ass kicked ('cuz she knows she'll get her ass kicked)," Rousey said, SB Nation quoted. "I would like me kicking her ass be my retirement fight but whether she steps up or not I'll walk away undefeated and happily ever after regardless."

Aside from challenging Floyd Mayweather Jr. and commenting on Cyborg, she also shared some inspirational words for women.

"For any woman trying to break into a male-dominated career, I'd say the greatest thing you can do is always keep in mind that you always have the right to be there."
