Her Instagram is usually filled with sweet, smiling selfies, shots of demure outfits and pictures of her adorable young son.
This typical social media persona is perhaps why Martine McCutcheon sent fans wild with a VERY cheeky snap on Instagram earlier this week.
Pictured in bed in a hotel room, Martine flashed a saucy smile and seemed perfectly happy to bare all in nothing but a tiny pair of pants.
She captioned the bold post: “After a long but fabulous day, it's a cheeky nighty night from me #thesavoyhotel #love.”
Fans took to the comments to congratulate her and tell her how fabulous she looks in the surprising post.
One user commented: “This is so empowering! I feel proud of you, work your femininity and sass. You look beautiful and happy.”
Another fan wanted to see more of her more carefree snaps, adding: “Very sexy Martine you should do this more often.”
However, some fans took a less favourable view to her somewhat out of character antics, and weren’t afraid to share their opinion.
I don’t really post anything like that very often. It’s very rare you’ll even see me in a swimsuit. But I’d had a couple of glasses of wine...
A disappointed fan posted: “I’m not sure you’re giving out the right signals to your girls.”
An even harsher commenter said: “Unfollowed – used to have more respect but if this is to help relaunch a failing career try something else. Nothing worse than a half naked has been.”
Martine brushed off brutal criticism as she shared the driving force behind the decision to post the picture – booze!
She told The Sun: “'I don’t really post anything like that very often. It’s very rare you’ll even see me in a swimsuit. But I’d had a couple of glasses of wine...
"I took a picture of my face and I saw my bum in the background and I thought: "Actually, that looks really nice". I said to my husband: "Shall I post it?" I’m normally a bit of a prude and don’t post things like that."
"I thought no one would take any notice of me. You’ve got all these supermodels like Gigi Hadid doing it and being a mum and my age, I didn’t think I would get that response!"
This snap has definitely put Martine back on the map – good timing, as she is just about to release her first track in fourteen years, ‘Say I’m Not Alone’.
