Ayda Field wants another baby

Ayda, 39, told The Sun: "I wouldn't say no to four. I've been asking for another one already. You have to ask. After that the shop would be closed. We'd be in a people carrier and we'd be done. It's been a miraculous experience and I'm super-grateful and if I can convince him for four then drinks are on me."

While his wife and children all want another baby after welcoming Coco via surrogacy, Robbie, 44, is not as keen as he doesn't want to be an old dad.

He said: "Teddy's asking for another one. Ayda's doing subliminals, I just don't know, I'm going to give it a few months to see how I feel.

I know people are having kids a lot older in life but when Coco's 30, I'll be 70.

"I'm 44 and my mum's still here, she's in her late seventies and I know how quickly life goes, and I'd like to be around for my kids."

Before welcoming Coco, Robbie and Ayda already had kids Teddy, five, and Charlton, three, together.

The couple recently announced they had become parents for a third time after a "long and difficult" struggle to have another baby.

Taking to Instagram, Ayda wrote: "I spy with my little eye an extra little hand ... 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 (sic)"
