‘I spy with my little eye an extra little hand 👀,’ Ayda wrote alongside a photo of the then family-of-five holding hands.

‘So we have been keeping a very special secret! 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.

‘As with Teddy and Charlie, we ask that you respect Coco’s privacy and allow us to grow into our new team of 5! #TeamWilliams’.

Big congrats to the whole family on their new arrival!
