Reports of their break up emerged after Dominic Cotton listed himself as 'separated' on the dating site, Match.com.
The BBC Breakfast host - who has three children with the former sports journalist - told The Daily Mail on Thursday, when asked if it was true they had separated: "I don’t think it would be appropriate for me to discuss this."
The 43-year-old's gruelling work schedule sees her commute from London to Salford at 3.30am in the week and the 'Strictly' tour has also kept her busy.
Susanna was a runner-up in the 2013 series after finding dancefloor chemistry with Kevin Clifton.
But she's not the first star whose relationship has hit the rocks after the show...
Countdown beauty Rachel Riley split from her millionaire husband of just 15 months following her stint on 'Strictly'.
Boxer Joe Calzaghe and Kristina Rihanoff got together in 2009 after he dumped his girlfriend just one week into the show.
And on the first first series of 'Strictly' in 2004 fellow newsreader Natasha Kaplinksy was rumoured to have grown close with Brendan Cole.
The pair were plagued by affair rumours – Natasha later dumped her partner of 12 years and Brendan ditched fellow pro Camilla Dallerup.
Meanwhile, it's thought Susanna is set to leave 'BBC Breakfast' and defect to ITV to present 'Good Morning Britain', which is being resurrected to replace 'Daybreak', according to reports.
The presenter is reportedly close to signing a huge £1million-a-year contract to present a revival of ITV's breakfast show, which was last on our screens in 1992.
However, last month she said her loyalties remained with the Beeb.
“My plan is to carry on turning up at BBC Breakfast at 5am and doing what I love,” she said.
