The 59-year-old, who has been stunning the nation with her incredible moves on the dancefloor, was married to the magician for 28 years before he passed away at the age of 77. 

And it seems they certainly enjoyed themselves, with Debbie detailing: "A good sex life is key. Paul is in incredible shape for a 70-year-old and he's got amazing energy. He always has."

Speaking in 2009, she went on to cheekily add: "When I first met him, he slept for four hours a night - if you know what I mean. 

"Even now, he never sleeps for more than six. He's still the rampant bull he once was.

"Nothing has changed. We keep each other interested. Every relationship has got to be the complete thing."

Her late husband also revealed details of their love life, writing in his autobiography My Magic Life: "Debbie was lying stark naked on the bed. Eat your heart out, fellas!

"She was wearing the sort of sleeping blindfold that you get on long haul flights. Printed on it was 'DO NOT DISTURB'. 

"Further down her body was a sign that said 'DISTURB'. Perhaps 'rolling on the floor' was not a good choice of words."

The shocking revelation comes after Debbie revealed she had been feeling "unpopular" with fans after she found herself in the bottom two.

She told host Claudia Winkleman: "When we were standing there tonight, I thought, 'We weren't very popular last week so we could be in the dance off again'."

Strictly Come Dancing continues Saturday on BBC One at 7.05pm.
