Las Vegas nightclub boss Jeff Beacher, who originally offered the two ex-husbands of Pamela Anderson $1 million to fight, has now upped the stakes in the hope of luring them into the ring.

Beacher said: "I've teamed up with legendary boxing promoter Bob Arum and now the prize is $5 million."

Earlier this month, Beacher claimed the pair were feuding over Pammy and offered them the chance to resolve their differences, saying: "We all know that they are fighting over Pam Anderson. What better way to settle their differences then to slug it out in the ring!"

Lee and Rock came to blows at the MTV Video Music Awards in Las Vegas' Pearl Theater at the Palms Casino Resort on September 9.

The scuffle was sparked after Lee reportedly muttered something to Rock as he walked past his table.

However, Lee insists he didn't provoke Rock, saying: "I was minding myself and then he goes and punches me on the cheek. I was trying to be the bigger man, but he was acting childish.

"I was ready to go in the alley and kick his ass. I was about to put Kid in the emergency room when security grabbed me. They said, 'If you move, we will break your arms.'"

The two men were pulled apart by security and Lee was escorted straight out of the venue.
