The Let Me Entertain You singer’s wife shared the news on Instagram, revealing that they had welcomed a gorgeous baby girl and announcing her unique name, Coco.
Now, just a week after welcoming the tiny tot, Robbie has finally broken his silence on becoming father of three – and opened up about family life, something he rarely does.
Speaking for the first time about their new arrival, he told The Sun: “Coco is the most chilled baby I’ve ever known.
“It’s funny. The first baby you have, ‘Shh, it’s sleeping,’ then you hear someone coming in that closes the door and you run downstairs and you go, ‘Shh! The baby!’
“Then the third one, the television’s on, the kids are playing, the dogs are barking, the baby stays asleep and the world doesn’t end.
“I wonder if the baby is so relaxed because we are relaxed.”
The doting dad also added that his other children – daughter Teddy, five, and son Charlie, three – have no jealousy towards their new sibling, and are all getting along famously.
On 7 September, X Factor judge Ayda announced the news that the pair were parents to another little tot.
“I spy with my little eye an extra little hand. So we have been keeping a very special secret!,” she wrote.
“We are delighted to share with you that we have had a baby girl….welcome to the world Colette (Coco) Josephine Williams!!
“It has been a very long and difficult path to get here, which is why we have kept it on the down low. 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.”
