Hearn, speaking in his Daily Mail column, pointed out that a Wembley showdown between the pair could match the earning power of Froch v Groves 2 and would be more lucrative for challenger Khan, 28, than any alternative.
“Talks are ongoing over a fight between Kell Brook and Amir Khan. It is going well because I think everyone realises it makes sense,” said Hearn.
“Khan obviously wants a fight with Floyd Mayweather, as does everyone in the division, but he knows that while that fight might never happen, even if it did he would make more money fighting Kell.
“Everything so far has been very straightforward and I am in talks with Wembley over a May date. They want us back there as soon as possible after the success of Froch-Groves and I have no doubt in my mind that we would fill that stadium again.
“I hope to have this tied up in the next month or so,” he added.
Brook claimed the coveted world title belt with a fine victory over previously undefeated Shawn Porter last month and is now in the big leagues regarding his purse potential – with Khan seen as the ideal starting point.
The 28 year-old is set for a lower-key defence of his title on December 6 in his hometown of Sheffield, before a massive showdown with Khan, possibly around May or June of next year, at the world famous stadium in London.
