She said: “Stress, I think caused mine. I’ve never been through the stress I’ve been through since I lost Paul.
“Grief hits you in so many ways you’re not expecting.”
McGee turned heads during the 2017 series of Strictly, reaching the final with professional partner Giovanni Pernice. Her foray into the BBC Saturday night hit show followed on from Daniels’ appearance in 2010.
In an interview with The Telegraph at the time, she said the show helped her turn a corner following his death.
“It gives me a reason to get up in the morning,” she explained.
“When Paul died, I couldn’t do anything for months. It’s grief – you have no motivation. I have always been someone who is happy in the morning and gets on with the day. With Strictly, I get up and want to be there.”
