The Matchroom boss says a deal is currently off the table as both fighters bicker over who should be the a-side in a second contest.
Haye took the honour first time around due to his superior reputation, although Bellew’s victory in their March meeting means the Liverpool man wants to be recognised as such.
Speaking to Sky Sports News on negotiations, Hearn said: “I don’t think Bellew-Haye will happen. Although there was hugs and kisses in the ring after the fight, trying to get these two to agree to anything is a complete disaster.
“Tony Bellew feels like he got the win, so he should get the benefits of that win, and David Haye feels like Bellew still isn’t on his level.
“When you’re talking about ring walks, who goes first on the poster, changing rooms, splits – all this kind of stuff, it’s impossible.
“I think at this stage, Bellew-Haye II is virtually dead,” he added.
Options for Bellew other than Haye or WBO champion Joseph Parker seem to be limited at the moment, whilst a move back down to cruiserweight looks a non-starter.
The current World Boxing Super Series tournament has tied up most of the title belts, meaning a smaller heavyweight option would be most likely.
A rematch with Adonis Stevenson at 200 pounds or a catchweight contest with Andre Ward have been explored, although someone in the ilk of an Amir Mansour or Steve Cunningham at 200 pounds plus could fit the bill for Bellew whilst he waits for Parker to face Hughie Fury.
