Stunt's divorce to ex-wife Petra proved to be incredibly bitter and he also went as far as labelling her billionaire father Bernie Ecclestone an 'evil dwarf' and a 'C-list celebrity'.
Having wed in a lavish, £12 million Italian ceremony in 2011, the couple enjoyed an extraordinarily extravagant life together, splashing out on a £100 million Chelsea mansion and a 123-room, £158 million home in LA.
But their marriage hit the rocks, sparking a bitter divorce battle last summer.
During a bad-tempered hearing, details of their marriage were laid bare, including hotly disputed allegations that Mr Stunt was abusive, violent and took overdoses.
The divorce proceedings were not short of controversy and Mr Stunt was even accused of making a 'gun gesture' to Petra's father Bernie Ecclestone at one point.
no details of the settlement were released, it was reported that James
signed a £16 million prenuptial agreement, with Petra also awarded sole
custody of the couple's three children in January.

‘It’s very early-on dating,’ she told Mail On Sunday's YOU magazine this weekend. ‘The whole thing is quite strange because my life didn’t pan out the way I expected it to. I thought I wasn’t the type who believed in divorce.
Familiar face: Samantha (here in October 2006) enjoyed a brief time in the limelight in 2005
'I go to church and I got married thinking I would be with that person for the rest of my life. But things happen for a reason and, whatever that reason is, I’ve now got my three kids.’
In her first interview since the divorce, Petra also spoke about being a single mother to their children.
‘Being a single mother is hard,’ she continued. ‘There’s no day off. You can’t take your eyes off them – it’s draining.
'Things like going on holiday are tough. Last week we were in Dubai and I had a nanny, but it’s not the same. You’re not a family.’
