This past weekend saw YouTube sensation Logan Paul go the distance with 50-0 boxer Floyd Mayweather over eight rounds in an exhibition bout.
It caught the attention of everyone involved in combat sports and Nunes, who holds bantamweight and featherweight gold, set her sights on Kardashian.
She jokingly posted on Twitter: "Hey Kim Kardashian, let's do this? Lol."
It was dubbed 'The Kardashian Charity Knockout' and she faced off with actress Tamara Frapasella in a losing effort.
Mother Kris and sister Khloe were very concerned as they looked on ringside and it was filmed for their 'Keeping Up With The Kardashians' reality series.
Despite this, fans have had a say on the potential fight and they don't fancy 'Kim K' getting a win.
One fan said: "The only way it would be a fair fight is Amanda fought blind folded lmao."
Another added: "Why tf would anyone wanna watch Amanda Nunes murder Kim Kardashian?"
While a third stated: "I would 100% pay to see Amanda Nunes vs Kim Kardashian."
Nunes' comments came after UFC president Dana White gave his thoughts on Mayweather vs Paul to UFC Arabia this weekend.
White has been vocal in his protests against Logan and brother Jake getting into boxing and he didn't hold back.
He fumed: "That wasn't a f*****g boxing match.
White on Mayweather/Paul: "Imagine if Kim Kardashian wanted to fight Amanda Nunes... There's always going to be a market for those type of fights and if you can pull em off and get people to pay 50 bucks for them, good for you! It's not what I do."https://t.co/rk4yQid8to pic.twitter.com/AZmfnq3c2f- Aaron Bronsteter (@aaronbronsteter) June 8, 2021
"Like I said before, there's always going to be a market for that kind of stuff.
"There's always going to be people that are willing to put down $50 to watch that kind of stuff. That's so far away [from what we do].
"Think about this -- imagine if Kim Kardashian wanted to fight Amanda Nunes. How big do you think that fight would be? It would be huge. It would be the biggest [event] but give me a f*****g break."
