Imogen, 32, is already mum to two-year-old Ariana, and she confirmed that the little girl is getting a sister!
Speaking to new! magazine, the former Big Brother star said: "I'm so pleased to reveal I'm having another little princess.
"I really wanted another girl, I just can't see myself with a boy."
It's bad news for Imogen's partner Adam Horsely, who's now going to have another girl running rings around him.
Imogen continued: "Deep down he would have loved a boy. But there's something about girls, they're daddy's girls. Ariana's got him wrapped around her little finger!"
And is Ariana excited about the new addition to the family?
"She doesn't really understand," glamour model Imogen added. "We have a scan photo on the wall and she looks at it and goes, 'Ugh'.
"But she's coming around. I've also bought her a baby so she can join in."
It sounds like Imogen's family is shaping up nicely, doesn't it?
Congratulations to Imogen, Adam and Ariana on their exciting news!
