It's pretty clear the pair are still very much loved-up, after only just celebrating their first wedding anniversary, but following continued speculation about their marriage, Mark has appeared to speak out on social media.
He cryptically addressed the rumours all is not well between himself and Michelle, by sharing a quote on Instagram that read: "Relationship where people know of us. But know nothing about us."
Mark didn't add a comment alongside his post, but he did add an emoji that suggests he agrees with the sentiment it shares.
His response comes after Michelle addressed reports referring to her not wearing her wedding ring. She hit back on Twitter, after getting frustrated with the constant comments she was receiving on the subject.
Michelle tweeted: "'No wedding ring, no wedding ring' blah blah blah sooooo boring!!! Not that I have to explain but I'm SO sick of these stories... (sic)"
She added: "I work on camera so I take it off and put it somewhere safe...SIMPLE. Last night I went straight out after work. Hence the NO ring!!! That's the only comment I'm making!!!"
Mark and Michelle have been faced with rumours of marriage trouble, ever since Michelle jetted off to South Africa for several weeks to film for BBC drama Our Girl.
They, however, have continued to put such speculation to bed, and not only did they put on a united front at this year's BAFTA Awards in May, but Mark was seen gushing over Michelle on their first wedding anniversary just weeks later.
Michelle, meanwhile, told fans that she was "so proud" of husband Mark, following his success at Soccer Aid 2016, earlier this month. Mark had scored the opening goal of the match, helping England to secure their 3-2 win and he was chosen as 'Man of the Match."
Michelle had been watching in the stands with Mark's family and tweeted following the game: "Amazing night! SO proud of @MarkWright_ for absolutely smashing it!"
He had shared a new photo of himself and Michelle cuddling up together in the dressing room and told fans he "couldn't have wished for a better prize" waiting for him.
Mark and Michelle married on 24 May 2015. The pair initially met in December 2012, and went on to get engaged nine months later in September 2013.
