The mum-of-five opened up to former housemate Nadia Sawalha, who was evicted from the Channel 5 show last Friday.
Loose Women panellist Nadia said: "She just wants another child. Well, she wants two more. She was trying to think of names."
Nadia also revealed how Katie had bared her soul to her about her marriage to Kieran Hayler, who cheated on her with her best friend Jane Pountney – and confessed she was desperate to 'make it work'.
Nadia told The Sun: "She talked to me about how much she loved Kieran. She was saying how much she was going to make it work."
Nadia said she had always been a fan of CBB – but regretted signing up.
She said: "If I could turn back time, I wouldn't do it. I think it's knocked ten years off my life."
Perez Hilton's chum also claimed her husband, telly producer Mark Adderley, had been ill with the 'stress' of watching her in CBB.
"He was running a campaign to get me out of the house. He couldn't understand what was going on and why I was friends with Perez.
"He said he couldn't possibly be seeing everything."
Katie is devoted to her kids and last year shared a fun photo of them snuggled up to baby Bunny, who was born last August.
