Katie 35, wore a flesh-coloured bodysuit printed with her book covers. Sticking with the theme, the model, who gave birth to her fourth child Jett Riviera in August, posed alongside a large lipstick and a pink heart.
Right by Katie's side was her husband Kieran Hayler, as well as her mother Amy and brother Daniel.
After the photo call, Katie took part in a small Q&A where she revealed: "I've had a break for the past year what with carrying Jett, well, I've had a break for three years really. Like Arnold Schwarzenegger said: 'I'm back now'!"
Even though Katie has just launched this autobiography, she's already started on her next one! "I've got four chapters already for the next book, and trust me, it's explosive," she tells us.
After the Q&A, we grab an exclusive chat with Katie who tells Reveal about life with baby Jett, why Kieran is the one, and why she found talking about her past marriages with Peter Andre and Alex Reid for Love, Lipstick and Lies hard to write.
Watch Katie in the video below:
Katie wrote her book in partnership with Rebecca Farnworth, and says it aims to provide an "intimate access to her side of all the stories with her own special brand of humour, compassion and total honesty."
Love, Lipstick and Lies charts Katie's bitter dispute with first husband Peter Andre and her highly publicised divorce from Alex Reid, to the romance and split from Leandro Penna, and a whirlwind marriage and surprise pregnancy with Kieran.
Love, Lipstick and Lies is available now.
