One of the photos showed the loved-up couple together on a dreamy vacation, and Michelle looked like a glamorous model as she enjoyed herself while wearing a tiny black bikini. The pair were relaxing on a boat out on the open waters and the Brassic star threw her arms into the air as she carried a small drinks bottle. Meanwhile, Mark was fully reclined in front of her, holding another bottle of the same beverage.

Michelle also shared several other photos of the pair, who have been together since 2012, including a romantic shot of them walking hand-in-hand together.
They walked through some farmland with their pet dog, Pip, in tow, and the actress shared a beautiful caption, as she wrote: "Here's to me and you third-wheeling forever! Love you."
The brunette beauty also shared a photo collage of some adorable moments that Mark and Pip have shared over the years.
"Happy birthday to the best husband and more importantly Pip's best friend and light of her life," she wrote.
Mark turned 35 on Thursday
The former Coronation Street star and her husband recently enjoyed some time in Mexico where Michelle shared a beautiful photo of Mark as he headed down to the beach.
The radio presenter wore a pair of striped swim shorts and was carrying a bag, as he walked down the wooden steps and towards the crisp waters.
Michelle only captioned the gorgeous shot with the heart-eyed face emoji.
The shot would make travel guides blush as it highlighted the natural beauty of the area, complete with plenty of palm trees to provide a bit of shade and a long stretching beach in front of the refreshing waters.
