Coleen and Wayne have just celebrated their seventh wedding anniversary (although they've been together a total of 13 years) and they already have two sons, five-year-old Kai and two-year-old Klay.
They may not know yet what sex the new arrival will be, but Coleen has hinted in the past that she would love to have a little girl.
Speaking shortly after giving birth to Klay in 2013, she told Hello! Magazine: 'I'd probably like another one - not too soon though. I think a girl would complete the family but because the boys get on so well, another boy would be just as nice.'
