Rumours that the ex-glamour model would be making a surprise late appearance intensified today with a new claim that she has agreed a mega-money deal to become a housemate.
According to Daily Star, she's been lined up to replace Ken Morley, 71, and Jeremy Jackson, 34, who were both kicked out of the house less than a week into the new series.
The newspaper claims Katie, 36, has decided to put her wedding renewal vows to cheating husband Kieran Hayler on hold so she can enter CBB.
A rep for Katie declined to comment when contacted by us.
If Katie does go in, we predict PLENTY of fireworks!
Katie was old pals with US gossip blogger Perez Hilton, 36. She hung out with Perez in Los Angeles while she and then-husband Peter Andre were living Stateside for Peter's music career.
Perez even helped Katie and Peter set up their first Twitter accounts!

Katie has history with other housemates as well, including controversial Katie Hopkins who made a dig at Katie's choice of 'Bunny' for a baby name.
It's rumoured CBB bosses will throw Katie into the house tomorrow night, shocking the current housemates and no doubt causing plenty of drama as they've all now bonded (or not!).
Katie is no stranger to reality shows. As well as starring in dozens of series of her own fly-on-the-wall documentaries and those with now ex-husband Peter, she appeared on I'm A Celebrity... Get Me Out Of Here! and starred in a TV series attempting to find a new celebrity for her to manage.
Interestingly, Celebrity Big Brother's Bit On The Side host Rylan Clark was one of the contestants who tried out for Signed By Katie and has remained close friends with the model ever since.
