The mother-of-five told The Mirror she'd stumbled across recordings of her partner, 28, online, whenever he was the lead singer in an indie band in his youth.
So far, the recordings haven't reached the public eye (or ear) but they may well do in the future if Kieran doesn't behave himself.
Katie, 36, said: "He wouldn't let me hear what they sounded like. Then I found them online and I keep threatening to put it out on Instagram. I was like, "Oh my God, is that you?' It doesn't even sound like him – and he was the lead singer."
Anybody else rather tempting to do a little Googling right now?! Kieran as a rock singer – we can't imagine it!
Katie's had a brief recording career herself: she launched an album called A Whole New World in 2006 which included a duet wit then-husband Peter Andre.
She also made a bid to represent the UK in the Eurovision Song Contest 2005 with the track 'Making Your Mind Up'.
Just this month, she teased she was planning on new music releases by sharing an image of herself in a recording studio.
