Joshua and Wilder were lined up for a blockbuster in Saudi Arabia with negotiations ongoing for between the two camps.
But AJ’s friend Bellew – who was also promoted by Eddie Hearn – believes they are instead looking in Fury’s direction.
He told Bitcoin Casinos: “I am hearing rumours that [talks between AJ & Wilder’s camps] have stopped at the minute and [AJ’s camp] are looking more towards Fury vs AJ again instead of AJ and Wilder.
“The talk is of another fight going to Africa, which would be absolutely incredible.
“Rumble in the Jungle all over again in Zaire or something along those lines.”
Fury, 35, returns on October 28 in Saudi Arabia against ex-UFC champion Francis Ngannou, 36, in a massive crossover clash.
It followed after talks of a title unification against Oleksandr Usyk, 36, collapsed although the Ukrainian hopes the fight can be revisited.
Joshua, 33, meanwhile knocked out Robert Helenius, 39, last month and called out Wilder afterwards.
But Hearn admitted AJ could fight again in December if Wilder, 37, cannot be ready by the new year.

He said on iFL TV: “Talks are ongoing. We are still in the same position of a January fight.
“If we don’t conclude that fight and they about moving it to February or March, we will probably fight in December.
“Wilder is talking about fighting in October, but it’s already September now.
“He will wait to fight Wilder in January. He’s training now. He wants to fight in December.
“If they turned around and said, ‘Let’s do the Wilder fight in December’ he’d do it.
“But everybody is talking like it’s happening, but until it’s happening it ain’t on. Until it’s on, we’ll keep our options open for December.
“Ideally, we’d like to go straight into the Wilder fight.”
