The pregnant model admitted she was struggling to find good names for her unborn child during an appearance on ITV's Loose Women today.
Katie already has sons Harvey, Junior and Jett, and daughter Princess.
She said today: "I'm stuck for names because of Princess. I have to name it something probably as crazy as Princess."
Princess' full name is Princess Tiaamii Crystal Esther Andre.
Katie, 36, is seven months pregnant with her fifth child. Reports have suggested it's a baby girl and although Katie hasn't confirmed it herself, she has hinted at it in interviews.
It's been a difficult pregnancy for the star as she discovered husband Kieran Hayler had been cheating on her throughout it.
On 7 May, the devastated model tweeted that Kieran had been having a seven-month affair with her best friend Jane Pountney. She claimed it started shortly after she gave birth to son Jett last summer and continued after she fell pregnant again.
Katie's fifth child will be her second with Kieran.
Her pregnancy with their first child, Jett, was also troublesome, as Katie went into labour while abroad after her amniotic sac tore, leaving her unborn child at risk of infection.
Jett was delivered several weeks early and had to remain in hospital for some time.
Katie explained on Loose Women: "Because Jett was born in France. I had to translate his birth certificate into English. They said 'how did you get him in the country?' I said by plane - not a domestic one because he was premature - a private one. Not as in private that I paid for it, I had holiday insurance.
"So they wanted to know what doctors were on board, the number of the flight, and I'm thinking all this! I haven't taken the baby! It's just a drama isn't it."
