The 37-year-old former glamour model, whose last offering was 2010 track 'Free To Love Again' which suffered from poor sales and was criticised for relying heavily on autotune, revealed she has been working on solo material.
After popstar Karava revealed the pair were working together, Katie took to Twitter to clarify: "I did a favour 4 @kavana_official but NEVER discussed doing duet in fact I'm in studio recording my own tracks solo (sic)."
Katie's tweet came after 'I Can Make You Feel Good' hitmaker Kavana insisted they were working on a duet.
He said: "We've decided to do a duet. I mean, God bless her, she can't really sing, can she? But I've said to her that I'll get her in the studio and make it sound good."
Katie, 37, enjoyed hits with her ex-husband Peter Andre, 42, including a cover of Disney's classic 'A Whole New World' in 2006.
She also auditioned to be the UK's 'Eurovision Song Contest' entry in 2005 with 'Not Just Anybody' but lost out to R 'n' B singer Javine.
However Kavana, 37, who joined supergroup 5th Story last year, is adamant he can make it work with Katie.
He told The Sun newspaper: "It's going to be a Nineties dance track with a Nineties vibe. Trust me, it's going to be a great song.
"We're writing it together. She loves to sing."
