Kerry Katona has discovered she is having a baby girl after being told by doctors she was expecting a boy.
The Atomic Kitten singer - who already has daughters Molly, 12, and Lilly Sue, 10, with her first husband Brian McFadden, and Heidi, six, and five-year-old son Max with her second spouse Mark Croft - thought she was preparing to welcome a son into the world with her fiancé George Kay.
The reality star told the new issue of OK! Magazine: "I went for my 12-week scan and I was told there was an 86 per cent chance it was a boy and even though you can't properly tell until 20 weeks, we took it as a definite.
"Then when we went for our 20-week scan, the doctors told us it was a girl. We were just in shock."
The pair said their unborn baby appears to have already developed a sense of humour after the mix-up.
Ex rugby player George said: "I didn't believe it. It was funny, when they were trying to check the sex, the baby rolled over and held up two fingers on the scan! "
The couple are now trying to decide on a name for their baby girl and admit they are struggling.
George revealed: "We're having problems picking a girl's name. Mind you, we might pick the same name for our little girl as we'd chosen for the boy as it's a unisex name."
Kerry, 33, was initially planning to walk down the aisle for the third time this year, but she has decided to put the nuptials on hold until after she's had the baby and lost the extra pregnancy weight.
