Celebrity boxing promoter, Damon Feldman said the offer came from billionaire Alki David who will also give another $1 million to charity if the two R & B stars agreed to his proposal.
“Obviously they have a grudge. It’s just three 1-minute rounds. No one will get seriously hurt,” he told the Daily News.
The event, which could be in Las Vegas or Los Angeles, will be broadcasted via pay-per-view, and “the bone of contention”, Rihanna may be the ring girl at the fight.
Chris Brown’s camp said they have never heard of the offer.
