Her former husband is no stranger to scraps, and now Mona Dotcom, 26, is gearing up for a fight - but this one will be for philanthropic purposes.
The Coatesville socialite - weighing a minuscule 51kg - has been invited to take part in the annual Fight for Life event, and organisers believe she'll bring some fashionable female glamour to the celebrity billing, which has typically been the domain of reality TV stars.
"Mona will make headlines, for sure. She seems like a lovely girl, and if we could find the right opponent for her, we know the bout will really rate," said Duco's David Higgins.
He means weight class. Finding a celebrity opponent in a similar weight division will be a challenge.
"We need a Kylie Minogue or Eva Longoria, or someone similar," he added.
Dotcom has never boxed competitively before but is seriously mulling over the idea. "It could be fun," she said.
She's committed to living in New Zealand, she told The Diary, and wants to do what she can to support Kiwi causes. She is working on various business opportunities and carving out a new life for herself and her children.
Fight for Life takes place on December 6 in Hamilton in support of Hospice Waikato. Half a million TV viewers are expected to tune in, with a live audience of 5000.
So, which skinny minnie celeb could spar the mother-of-five? Names being touted include TV3 presenter Sacha McNeil, actress Kim Crossman, socialite Gilda Kirkpatrick and rugby WAG Honor Carter.
The Sonny Bill Effect
He's a devout Muslim who doesn't drink booze or touch ciggies, and his sobering ways are rubbing off on rugby league teammates.
You won't find a beer in the changing rooms these days, says former Roosters skipper Luke Ricketson.

"Sonny Bill Williams has helped turn us into a modern-day club. There's no drinking, there's no smoking [and] there's none of the partying habits than can drag rugby league down," Ricketson told The Australian this week.
Er, we're not sure SBW will have quite that effect on Steinlager, sponsor of the All Blacks, when he flip-flops back into the team soon.
Snedden's new bout
Martin Snedden has a new job.
He stepped down as boss of the Tourism Industry Association earlier this year and took up a role as chairman of the International Cricket Council's governance review committee.
Now Snedden has been appointed Group Chief Executive Officer of Duco, promoters of the $7. 5 million NRL Auckland Nines and the country's premiere boxing events and prizefighters, including heavyweight champion Joseph Parker.
Snedden, a former lawyer and cricket legend, is no stranger to high- profile sports administration. He made his corporate hotshot name as chief executive of New Zealand Cricket and boss of the Rugby World Cup organising team.
Duco founders David Higgins and Dean Lonergan believe Snedden is capable of expanding the firm on the international stage.
"Dean and I have a lot of respect for what Martin has achieved with New Zealand Cricket and the Rugby World Cup. He doesn't appear to put a foot wrong," Higgins told The Diary.
"We think he can help smooth out Duco's rough edges and take the company to the next level and expand our sporting franchises in the South Pacific."
Stephie skips election night
She was on the SkyCity stage three years ago celebrating her father's election victory, but Stephie Key won't be returning home for Saturday night's election outcome.
The 20-year-old student is studying at the prestigious Paris College of Art, an American private university with four campuses in the French capital.
The Key family won't be all together on election night as daughter Stephie (far left) has just started back at uni in Paris.
She has just started back for the uni term and can't skip classes. "I told Stephie I would Skype her," her dad told The Diary yesterday.
Pity. Stephie, friend of sartorial sushi and raunchy self-portraiture, would have added quite the youth glam spice this election night.
Key will have sibling support, however.
Big sis Liz and her husband Roger are jetting in from London, while sister Sue and her husband Malcolm are making the trek from Christchurch.
