Over the weekend, it was suggested that Lee and his professional partner Nadiya Bychkova had been struck down by the so-called “‘Strictly’ curse”, when they were snapped on the front over of The Sun holding hands.
While Lee did not address the pictures head-on, it looked like he was keen to prove that his relationship with Nadiya was strictly professional, with a post on his Instagram account.
Sharing a photo with his ex-girlfriend Samantha Janey - with whom he has a 10-year-old daughter - holding hands on a day out together, he captioned the image: “If you can’t laugh, you’ll cry.”
Later in the weekend, Nadiya posted her own photo, in which she and her footballer fiancé, Matija Skarabot, were seen looking loved up as they posed together in a mirror.
She wrote: “Perfect Sunday… Be happy in the moment.”
Although best known for his work as a singer in Blue, Lee famously appeared on Channel 5’s ‘Celebrity Big Brother’ back in 2014, where he made headlines for his romances with both Casey Batchelor and Jasmine Waltz.
