After beating Dillian Whyte, Fury seemingly retired from boxing. To the surprise of no one, he now has his heart set on making a comeback.
Oleksandr Usyk is not willing to fight again until next year as he wants to spend some time in Ukraine with his family.
So with that fight off the table in the short term, Fury has turned his attention back to Joshua.
'The Gypsy King' has challenged his fellow Brit to a world title fight with him eyeing a return before the end of the year. Joshua soon responded saying that he would be ready to fight in December.
"I would love to get really excited about this," Hearn told talkSPORT.
"Because it's the fight that I get stopped in street for more than any fight that could be made and it's a fight that AJ has wanted for a long time.
"Don't forget, we signed for this fight last year before the arbitration forced the Deontay Wilder fight for Tyson Fury.
"So, it's an interesting one, because last week he retired, then he came back to fight Usyk, then he made an offer to Derek Chisora, then he wanted half a billion, then he'd retired again, then he's fighting Usyk in December and now he's fighting AJ.
"The message is quite clear from AJ, we don't want to get involved in a backwards and forwards, we want the fight, it's the fight he's wanted for a long time.
"We had plans after the Usyk defeat to come back in December and then go again in March, get active and get the rhythm going again and then try and fight for the world heavyweight title.
"But, I know having spoken to AJ, if that fight is there and they're serious, which I have my doubts about, but for the good of trying to make it happen let's believe Tyson Fury and I said to George Warren last night, get the details and the offer over to us and I'll take it to AJ, he's ready to go.
"We didn't expect this opportunity, but it's a great opportunity to fight for the world title in the biggest fight in boxing and we will definitely look at it.
"For me and the cynic in boxing, this smells of, 'Oh, we couldn't agree the AJ deal so I'm fighting this bloke you've never heard of instead, but no one else was available.'
"But let's take the cynic away and see what we get back from the Fury camp, because we're ready to discuss it and we're ready to make that fight for sure."
Hearn went onto claim that Fury's comments in recent weeks over social media are "unbelievably bizarre".
"Fury's outstanding at getting the public to believe absolute nonsense," he added.
"It worries me actually what people do believe, if you look at the timeline over the last two or three weeks, it's unbelievably bizarre.
"Personally, I don't believe Fury is serious about this, but if he is, which I said to the Warrens last night, 100 percent we will sit down and make the fight."
Fury was quick to respond to Hearn's interview on talkSPORT, as he reaffirmed his stance that Joshua is who he wants to fight next.
