Their marriage has been back on track after she kissed dance partner Seann Walsh on a night out.
It came as the couple took part in a game alongside their fellow Strictly pros where they had to guess some of the most outrageous facts about each other, with Katya’s secret leaving Neil numb with shock.
Neil and Katya joined their fellow Strictly pros in being asked which of them had tried to snort spaghetti up their nose.
Giovanni Pernice was quick to add: ‘Which pro is weird? That’s what you’re asking me. Which pro is the weirdest one? Spaghetti from the nose?’
Janette Manrara was quick to issue a firm warning to her husband Aljaž Škorjanec, telling him: ‘Aljaž, if you ever put spaghetti up your nose you’re going to get it from your wife.
‘So this better not have been you. I can definitely see him being dared to do it and having done it.’
But lucky for Janette and Aljaž the guilty party was in fact Katya, as she quickly told the camera: ‘Oh, come on guys! I thought you’d get that! It’s obviously me!
‘I once ate spaghetti through my nose. Please don’t try that at home.’
The revelation about his wife left poor Neil utterly shell-shocked, telling the camera: ‘What? I’m not cooking pasta for her ever again!’
This shock revelation comes after Katya faced an enormous fallout alongside comedian Seann Walsh, after the pair were spotted sharing a kiss together on a night out in London.
The comedian issued a feeble apology in which he blamed his actions on alcohol, while Katya echoed the sentiments however insisted her marriage to fellow Strictly Come Dancing professional Neil is fine.
However it appears that Katya’s other half has reason to worry again, as the pair are said to be dancing together for the finale in a few weeks, according to The Sun.
A source told the publication: ‘Neil will be gutted as when Seann was voted off the show, he was glad to see the back of him.
‘Since he went, the atmosphere backstage has improved and Neil has been visibly happier.
‘Things are back on track in his marriage – so he’ll be gutted when Seann is back on set.’
