Ronda Rousey dropped another bombshell piece of news, this time admitting her upcoming fight with Amanda Nunes is likely to be one of her final fights.

"This is definitely one of my last fights," the UFC fighter told Ellen DeGeneres in an interview set to air on Thursday. "Everybody better watch because the show isn't going to last forever."

New York Post reports that Rousey is set to return to the Octagon for the first time in more than a year when she takes on Nunes for the UFC women's bantamweight championship at UFC 207 on December 30.

Besides the talk of retirement, Rousey opened up about the mental exhaustion and nerves she suffers through in the lead-up to a big fight.

"I think it's more the build-up that's more tiring than anything else," Rousey said.

"It's the weeks and weeks of build-up beforehand. You know you're going to fight this one person, and it's like your showdown, and the most important thing in your whole life, and then millions of people are watching ... If it just happened right now I wouldn't be nervous at all."

"It's the waiting," that causes Rousey the most trouble.

While Rousey's critics are likely to jump on her for admitting that the pressure gets to her, the former champion seemed comfortable talking to Degeneres about her mental health.

It's not the first time she's done so.

After her devastating head-kick loss to Holly Holm at UFC 193 on November 15, 2015, in Melbourne, Rousey appeared on DeGeneres' show and admitted to being suicidal immediately after the Holm fight.

"I was down in the corner [of the medical room], and I was like, 'What am I anymore if I'm not this?' I was literally sitting there and thinking about killing myself," Rousey told DeGeneres in 2015.

"In that exact second I'm like, 'I'm nothing'."

Even though suicide is something that Rousey takes incredibly seriously - her father killed himself when she was young - her opponents and detractors were quick to make fun of her. Rousey never responded to any of her critics and dropped off the media radar for much of the past year.

Her appearance on The Ellen Show is her first major interview since her UFC return was made official in October.
