The 36-year-old has tried – and failed – a couple of times in the past to become a pop star and her latest Instagram snap suggests she hasn't given up.
Alongside the picture of her in a booth, Katie wrote: "Loving my day in the studio recording [sic]"
Fans of the former glamour model will remember her duets album with ex-husband Peter Andre, and her feisty single Free To Love Again shortly after their split.
Last month Katie teased that she's collaborated with her former Celebrity Big Brother housemate Kavana.
Sharing more pictures to Instagram, Katie said: "Woo video shoot with Kav [..] Enjoyed doing video shoot today can't wait to do my own [sic]."
Speaking during promotion for Free To Love Again in 2010, Katie admitted: "I'm not the best singer but having so much fun doing it [sic]."
The mum-of-five has often stated that her only regret in life is doing Eurovision in 2005. At the time she was pregnant with first child Harvey, and wore a tight pink rubber catsuit to perform on the preselection show Making Your Mind Up.
Are you looking forward to hearing Katie's new music?
