"I told them that if that's true - and everybody involved really wants to do it - we can talk."
And Dana admitted he'll do whatever he can to get the 25-year-old singer to face off against the 56-year-old action star.
He said: "I'd be an idiot not to make this fight... That would be the easiest fight to promote in the history of my career."
After previously insisting he was making a joke about the potential fight, the 'Never Say Never' hitmaker also admitted he didn't fancy his chances if he did grapple with Tom.
He said: "I'm pretty sure Tom would ... I'm pretty sure he'd whoop my ass in a fight. I'd have to get in good shape, I'm really skinny right now. I think he'd probably be out of my weight class. Because he's big, you know he's got that dad strength."
In his original tweet, the Love Yourself singer gave no reason for wanting to fight Tom, but said he wanted to take him on in "the octagon", which is the type of ring used in UFC.
He wrote: "I wanna challenge Tom Cruise to fight in the octagon. Tom if you dont take this fight your scared and you will never live it down. Who is willing to put on the fight? @danawhite ? (sic)"
