The loved-up couple - who got married in 2015 - have been forced to endure a long-distance relationship since last year as she has been away filming army drama 'Our Girl' in South Africa, Malaysia and Nepal and her beau now presents the US chat show 'Extra' alongside Mario Lopez.
But, to ensure their marriage survives their busy work schedules, the 30-year-old actress makes sure they are never apart more than a month at a time and they make time for date nights.
Speaking to Daily Mail newspaper's YOU magazine, she said: ''We try not to spend more than three weeks apart, although the longest we've gone is six weeks which was really difficult.
''We miss each other and staying in is our favourite date night. A lot of the time I don't think about where we are. If Mark is there it's home for me.''
Michelle has been auditioning for roles in the US since Mark, 31, bagged his presenting gig across the pond so that they can spend more time together, but she has admitted British drama is more her type of thing because she's a ''northern girl'' who misses her family and school friends.
She explained: ''It's just not me, I'm not an LA woman.''
And, although they've managed to make things work so far, Mark - who shot to fame on 'The Only Way is Essex' in 2010 - has admitted he'd quit his job if Michelle asked him to.
He said: ''Yes I miss [Michelle], yes she misses me. Right now we make sure we see each other as much as we can. I mean if Michelle didn't like living here and she wanted me to move home and she preferred life back home, then for sure I would [move back]. That comes first. It's not going to come to that, but if it ever did, then yes of course, marriage and my love life is definitely first.''
