UFC champion Amanda Nunes has sensationally challenged TV star Kim Kardashian to a fight in the Octagon.
Brazilian-born Nunes is the reigning champion of the UFC women's bantamweight and featherweight divisions.
She jokingly called out Kardashian in a tweet that reads: 'Hey Kim Kardashian, let's do this? Lol.'
This is coming after YouTuber Logan Paul fought Floyd Mayweather.
UFC president Dana White even commented on 'how big the fight would be' if the Keeping Up With The Kardashian's star accepted the challenge.
