Robbie Williams and Ayda Field shocked the nation when they revealed they'd had a third child via surrogacy.
The pair announced the news on Instagram and it didn't just surprise us, but their boss Simon Cowell too!
For the first time, the former Take That star has revealed how baby Coco Josephine has settled into their family weeks after she was born.
Speaking to Mirror Online, Rob said, “Coco Josephine Williams, she’s the most chilled baby that we've ever had out of all three of them and it’s interesting, the progression being a parent, from the first child where, when they go to sleep, if you hear something two miles away you wanna send somebody two miles away to tell them to s**t up.
“Then on the third one, you know, the kids are fighting, the TV’s on and baby stays asleep and I think because we’re more chilled, she’s more chilled.”
Most parents are worried their elder children will be jealous of the newest arrival, but it's been a doddle for the X Factor judges, who are also parents to Teddy, five, and three-year-old Charlie.

Robbie added, “The kids, there’s no jealousy, there’s just lots of love.
"Teddy wants to feed her all the time and cuddle her all the time, and we keep waiting for her to be a nightmare, but so far she hasn't done anything other than sleep, drink and occasionally smile and then get confused about what she’s doing."
Ayda, 39, has also revealed her joy at being able to welcome a third child.
“It has been a very long and difficult path to get here, which is why we have kept it on the down low," she said.
“Family comes in all forms, and this little lady, who is biologically ours, was carried by an incredible surrogate mother, to whom we will be eternally grateful.’
“We are over the moon to have this beautiful baby girl in our lives and so blessed that we live in a world which makes this possible."
What a perfect little family!
