Not that he found them unattractive... quite the opposite, in fact.
Katie has indeed vowed to never to wear a onesie again after catching husband number 3 Kieran Hayler cheating on her with friend Jane Pountney at her onesie-themed party. True story.
The former model - who threatened to divorce the 28-year-old hunk last year after finding out about him playing away - has claimed the she caught the pair walking up to her horse stables together on a security camera at her house while her other guests partied at the fancy dress bash.
Speaking on an episode of Channel 5 reality show Celebrity Big Brother, which she was reportedly paid £500,000 to appear on, she said: "Whenever I do parties they are always fancy dress because I think people make an effort. So this was the first year I didn't because last year I did a onesie one and Keiran and Jane f***ed in my stables so I will never wear a onesie again. It was on the cameras, it was one o'clock in the morning on my cameras. You can see them walking up to the stables and I never knew, everyone was in my house partying. Don't mess with the Pricey!"
The 36-year-old star also revealed she once attacked Jane, 49, after finding her sharing an intimate moment with Kieran - who also cheated on Katie with her pal Chrissy Thomas - on a beach while they holidayed together.
She said: "I got her head and pulled her off the sunbed, I started f***ing whacking her, going 'I f****ing knew it, I knew it, you f***ing s**t, you w***e'."
Price - who has two kids with Kieran, and three more from previous relationships - has vowed to stand by her husband, whom she married in January 2013.
The couple - who recently moved to a new £1.3million home - are said to have left the property so Katie could leave memories of Kieran's stable romp behind her.
