Two Australian billionaires apparently started punching each other in broad daylight last week when one confronted the other about dating Victoria's Secret model Miranda Kerr after leaving his wife and children last year.

According to reports, billionaire Australian media moguls David Gyngell and James Packer ended up rolling around on a Sydney sidewalk last Sunday when Gyngell confronted Packer on the street outside his home.

Gyngell, a childhood friend who also served as Packer's best man in 2007, was apparently concerned with the way Packer had been treating his estranged wife since their split.

"He fully accepts that he was the instigator of the incident," a spokesman for Gyngell told the Daily News. "Clearly, had he not turned up at Packer's premises in an angry mood then the confrontation would never have occurred."

The men had to be separated by their respective bodyguards and both were fined $500 for "offensive behavior."

Packer walked away with a black eye but declined to press charges against his childhood friend.

"We have been friends for 35 years and still are," the pair said in a joint statement.
