Her estranged husband Michael was so furious when she posed in lingerie two years ago, he didn't speak to her for several days.
But after the recent heartbreaking revelations he is dating one of their Ultimo designers, lingerie tycoon Michelle Mone is free to do what she pleases.
Currently in Dubai with their three children for an Easter holiday, Michelle made a pop at her ex by posting a photo of her toned figure in a bikini - something which would have infuriated him if they were still together.
After her initial devastation at discovering her business partner husband Michael, 46, was in a relationship with one of their friends and employees Samantha Bunn, 31, it looks like Michelle is feeling better.
The 40-year-old wrote on Twitter today: 'Having a ball with kids. Started my 8 week intense training, lots of egg whites, veg & Chris Brown. Why don't you do it too?'
Following her arrival in Dubai on Sunday, she headed straight out for a run.
She tweeted: 'Long run done along the beach very hot but it helps clear the mind.'
On Sunday, it was revealed Michelle has discovered her estranged husband's new romance with Bunn after hiring a private investigator.
News of their romance comes a few months after the Mones' shock split last Christmas after 19 years of marriage.
It has been reported Michael told Michelle their marriage was over as they prepared to eat Christmas dinner with the family.
Michelle was particularly hurt because she had a friendship with Bunn, often going for runs together and allowing the Derby-based designer to stay at their homes in Glasgow and Mayfair.
It was reported Michelle keyed Michael's beloved £120,000 Porsche following the discovery.
Following press revelations about Michael and Bunn, Michelle wrote on Twitter: 'Thanks 4 all ur support. I'm heartbroken, been saying since last year. I allowed her to stay in my home etc, all she did was lie. My priority are my kids & business.'
When asked for comment, Michael is reported to have said: 'There was no affair and what is happening now is private. Prior to our split, there was no relationship. If anyone is saying that is the reason for the split, that is untrue.'
Michelle's decision to tweet a bikini photo will be seen by some as a dig at her estranged husband.
After losing six stone, Michelle decided to show off her weight loss - and promote the Ultimo brand - by modelling some of their own lingerie in 2010.
However, she admitted at the time the shots had really upset her Catholic husband.
She said: 'Things are a bit frosty at home and it's the longest we've ever gone without speaking.
'He’s appalled. Every Sunday we go to Mass and I know he's worried about what people will say this week.
'He’s bothered on so many levels. He doesn’t want other men looking at his wife like that. He thinks it’s harmful for the kids. And he thinks it's detrimental for the business.'
Now she's single, Michelle is preparing to strip off for another Ultimo lingerie shoot in two months time.
Two months ago, Michelle, whose lingerie business had a £10.3million turnover last year, revealed her pain over the breakdown of their marriage.
She told the Sunday Times: 'I miss him. I miss what we had. I just keep thinking I'm going to be on my own for the rest of my life.'
Michelle founded MJM International with her husband in 1996, launching the first of her cleavage-enhancing Ultimo bras in 1999.
Michelle had read about a new silicone product while on holiday in Florida, and obtained the European licence to make bras from it.
