UFC champion Ronda Rousey was a guest on "The Tonight Show with Jimmy Fallon" and graced the show looking like she can knock you out — because of her sultry black dress.

As reported by The Washington Post, during her guesting at Jimmy Fallon's show, she spoke about how her fight usually doesn't last long. Of her 15 UFC MMA wins, both professional and amateur, only three of her opponents have lasted longer than a minute, with six ending in just a quick 30 seconds.

However, she promised her fans that her incoming fight with boxer Holly Holm is going to be different. How different you ask? Well she promised that it's going to be longer, much longer.

Rousey said, "She's undefeated and an amazing athlete, and definitely the biggest threat to me, especially on paper and stylistically." She added that Holm is the type of fighter that you have to be very patient and careful with. Rousey said that she feels that Holm will try to keep her distance and be as far away from her as possible then surprise her with a kick in the head.

However, Rousey assured her fans not to worry because "it's not going to go like that - not the way she wants."

But she did concede that she thinks that Holm is a "nice chick," and that she has nothing personal against her; unlike Bethe Correia, her last opponent, who earned the ire of both Rousey and her fans.

She was kind enough to say a bit of trash talk and said that "she's a nice chick who's gonna lose."

Rousey can be scary but as reported by Daily Mail, UFC Women's champion Ronda Rousey showed that she can be terrifying in the octagon, but can look womanly while outside.

The most dominant female athlete in combat sports was looking classy as she paired the sultry black dress with some towering heels, with her hair swept back and matched with dangling earrings.

In a similar report by Radar Online, the dress bares a bit of Rousey's breasts, but in a classy way of course.

And during her interview with Jimmy Fallon, she surprised her with a large platter of chicken wings because he heard that Rousey likes to devour juicy meaty treats after fights.

Unfortunately, she reiterated that she cannot eat them right now because she is currently in strict training for her upcoming fight and has to stick to her regimen.
