Katie, 35, officially unveiled her new book, Love, Lipsticks and Lies, today in London and, as usual, she successfully turned heads.
The former glamour model, who gave birth to her fourth child Jett Riviera in August, teamed her nude catsuit with a pair of matching high heels and a tiara.
Katie topped off her look with a giant pink marabou feather heart, which she placed around her neck, and she styled her hair into huge big curls.
Posing alongside a massive lipstick and hearts, Katie smiled and strutted her stuff for dozens of waiting photographers and reporters.
She later tweeted: "I've just had a fun photo shoot!"
Katie's book hits the shelves on Thursday (24 October), however she has already released some juicy extracts through a serialisation with The Sun newspaper.
Last week, Katie described how her first husband, Peter Andre, dumped her by telephone. She said she still does not know why he ended their marriage in 2009.
Katie also claimed she caught now ex-boyfriend Danny Cipriani "in bed with another woman", and that she did not sleep with Gavin Henson following her break-up with Leandro Penna last year.
One thing's for sure, this book is certainly going to be a page-turner!
