But just two months on and the 43-year-old is back in her smalls for the Adore Moi By Ultimo winter campaign. We're not sure how much more of her perfect abs we can take, quite frankly.
The TV presenter and mum-of-two looks incredible in the glossy campaign images, sporting suspenders, stockings and a retro veiled hat as she poses in a Parisian-inspired boudoir setting. Oo-er.
The new collection, available in Debenhams stores from today, channels, "the timeless feel of the French boudoir", but at affordable prices, with briefs starting at £8 and bras from £22.50.
Melanie, who makes posing in pants look easy, said of the latest collection: "The new Adore Moi by Ultimo collection is absolutely stunning - super luxurious, yet incredibly affordable, and it fits like a glove. I love getting dressed up in beautiful lingerie, there's nothing sexier.
"I always wear matching underwear, but if you want to really vamp it up there's nothing better than a gorgeous corset and stockings."
We know it's a lot to ask, but if it could come with the promise we'd look half as good as Melanie then we'd buy the whole lot.
