The engaged pair looked as glamorous as always as they arrived for the glitzy ceremony held in London on Wednesday night (22 January).
Michelle was stunning in a floor-length mint green gown by Philip Armstrong that showcased her year-round tan, teamed with gold rings on her right hand from MyFlashTrash.com, shoes by Next and a gold clutch from Artful Bag.
The NTAs are celebrating their 19th year this year. The awards were all voted for by the public and the ceremony, hosted by Dermot O'Leary, is shown on ITV.
Michelle was nominated in the 'Serial Drama Performance' category for her role as Tina in Coronation Street, a role which she'll be leaving when she bows out of the soap later this year.
She'd told BBC Radio 1 earlier in the day that she didn't think she'd win considering her competition: David Neilson and Julie Hesmondhalgh from Corrie and Jessie Wallace from EastEnders.
Michelle added to Manchester Evening News: "Because I had no real experience before Corrie, I just think it's such a huge honour every time I'm nominated for an acting award, especially as I'm up against Julie and David Neilson for this one."
In the end Julie won but thanked the entire Corrie family for contributing.
As well as being up for an individual award, Michelle was also cheering on Corrie in the best soap category. And it won!
During the night, Michelle took to the stage to hand out an award, but admitted beforehand: "I'm very nervous about getting on stage as I might trip, or swear or say something wrong." (She didn't!)
Michelle confirmed in April 2013 that she would leave Coronation Street after six years in order to pursue other projects.
She said at the time: "I will miss Tina and will always be grateful to ITV and Coronation Street for giving me such an amazing role to play for my first ever acting job. Most of all I will miss the amazing people who work on the show, my acting colleagues, cast, crew, producers and writing team. I have met people who I know will be friends for life.
"I am very excited about what the coming months hold for Tina and what the future has in store for me."
That future includes a wedding to ex-TOWIE star Mark, who popped the question during a romantic holiday to Dubai in 2013. The couple had begun dating the previous year after bumping into each other in Dubai while on holiday.
