She vowed to pose in a sexy lingerie shoot when she had reached her target weight of 11 stone.
And now Ultimo boss Michelle Mone has kept her promise, by stripping off for a new shoot after losing a staggering six stone in the space of three years.
The 38-year-old is following in the footsteps of Kelly Brook, Sarah Harding and Penny Lancaster by posing in her Ultimo range, and said she is thrilled to be able to show off her new slimline figure.
Michelle Mone, 38, said she was proud to show off her figure, after slimming down

She said: ’I spent ten years trapped in a body I hated, now I love the new me and I’m happy to show it off.
’For years I tortured myself about my weight. I was miserable, I hated myself. How I look today is the result of three years of hard work, and I want to end that on a high note and put all my insecurities behind me. It’s the end of a chapter and I won’t be doing anything like this ever again.’
And Michelle, who went from a size 20 to a size 10 after using herbal appetite suppressants, credits former Spice Girls star Mel B for helping her find the courage to fulfil her dream.

She told Hello! magazine: ’We were doing a campaign shoot in Las Vegas and I was fitting Mel’s bra, when she said, "You should do a shoot yourself - show off how great you look".’
Michelle Mone said Ultimo bosses were also against the shoot
But while Michelle is thrilled with the sexy new pictures, in which she poses in a variety of stunning underwear sets, she admits her husband Michael, to whom she has been married for over 20 years, was less than impressed.
She said: ’I sent him one picture after the shoot and he emailed back to say, "OK, nice - but you’re not releasing them".
’Although we’ve had our disagreements, I’ve never totally gone against my husband before. Not only does he think it’s a bad thing to do professionally, he’s a traditional kind of guy and doesn’t want other men looking at his wife in underwear.’
And her husband wasn’t the only one to disapprove of the shoot, as Michelle wrote on her website last month that Ultimo bosses weren’t sure if it was the right thing to do.
She wrote: ’My board are against me getting my kit off. But I want to show all women that, no matter what age you are, you can shed the pounds, get fit and look the best.’
Michelle added to Hello! magazine: ’A lot of people will be shocked to see me doing this, particularly in the business world. A company head has never done anything like it, so I know it’s controversial which is why I was petrified stepping in front of the camera.
’But I want to empower women and show them that if you’re really unhappy about your body, you have the power to do something about it. Look at me, I was 6 stone overweight and so unfit – but I managed to turn my life around, and you can too if you put your mind to it.’
