The bitter rivalry between the two boxers is set to come to a head when Danny Green joins I'm A Celebrity... Get Me Out Of Here on Wednesday night, news.com.au reports.
Green and Mundine, who have been feuding for 12 years, have met in the ring twice. Mundine won the first bout in 2006, and Green controversially won the rematch in 2017.
I'm A Celeb hinted at the reunion when they teased, "Two celebrities in the middle of Australia’s biggest feud will be heading into the jungle. This Australian duo are used to clashing in real life, but what will happen when they are forced to live alongside one another in the unpredictable African terrain?"
