Judy Murray, Frankie Sandford and 'This Morning' presenter Alison Hammond are also taking part.
Mark has shared his excitement ahead of the series, revealing that he’s slightly worried about being so far out of his comfort zone.
"Doing ‘Strictly’ is going to be so completely different from anything I've done before. I'm the sort of guy who loves to bust out some moves at a party but I'm certainly not a natural dancer,” he explains. “Any of my friends would tell you that - they call me Markey no-moves!”
“I'm genuinely petrified about dancing on national telly but ‘Strictly’ is such an amazing show to be a part of and I can't wait to get stuck in and give it my all!”
Despite previous reports, Mark’s fiance Michelle Keegan isn’t thought to be signing up for the show.
