The mother-of-five watched Nathan's interview on ITV's This Morning on Thursday where he spoke about having cosmetic surgery to emulate his idol.
Katie later tweeted at him: "Watched you on This Morning. You were fab. You're a very pretty, good looking guy xx."
Nathan had told hosts Phillip Schofield and Amanda Holden that he had met Katie plenty of times and she knew what he was doing.
"I've met Katie tons of times - about 15 or 20 times now at book signings and things like that. She's knows I'm doing it and fully supportive so that's pretty cool," he explained.
"She just thinks I'm crazy to be honest. But what can she say? If she said no I'd still do it anyway."
The 20-year-old has been fascinated by Katie ever since watching a documentary seven years ago and said that having the procedures had boosted his confidence and made him happier in his own skin.
It has come at a price, however, as he estimated he's spent around £40k so far.
"I spend all my wages on beauty treatments and stuff like that and my boyfriend pays the bills. He's on more money than me. I'm £20,000 in debt, I've had loans, credit cards… things like that."
That being said, he's still going to keep having procedures, with veneers and a bum lift next on his list.
