Katie, 36, arrived in the CBB compound with a bang and the thought of spending just one night away from Kieran, Harvey, Junior, Princess, Jett and Bunny doesn't fill her with much joy.
But although she won't be around at home, the former glamour model isn't worried about Kieran holding the fort.
Speaking ahead of her big entrance, Katie said: "Well he handles it anyway, because if I go to work he has the kids. He's really good with the kids and we're a good team.
"He will miss me and I'll miss him and the kids. That is my biggest thing, the family. It's going to be hard because I don't even like having a night away from them, but I know that is part of the deal and you just have to get on with it."
Katie's eldest child Harvey, 12, suffers a range of genetic disorders and disabilities, including blindness, autism, ADHD and Prader-Willi syndrome.
As a result, he needs extra special care and doesn't view the world in the same way his siblings do.
Katie adds: "It'll be Harvey who will find it hard because he doesn't understand about work, I am his absolute life. So it will be harder for him than any of them, but Bunny is only five months old and joined to me at the hip.
"Then you've got Jett, so I don't know."
Katie confirmed that Junior and Princess, who she had during her marriage to Peter Andre, will be going to stay with their dad while she is taking part in CBB.
"Junior and Princess go to Pete's," she said. "We split them half and half, so they'll be alright. It'll be me; I know I'll find it difficult."
