The couple - who have been married since 2010 and are now working together as judges on UK TV talent show 'The X Factor' - welcomed their third child into their family last month, daughter Coco, a baby sister for daughter Teddy, six, and son Charlton, three.
Ayda admits this is a special time for the Williams household and she is just so grateful to have another baby - who was delivered via a surrogate - as she didn't think it was going to be possible when she and Robbie were having problems conceiving.
Speaking on 'Loose Women', she revealed: ''Rob and I and the kids are over the moon, we're in a pink love bubble now. I feel so, so grateful. I just didn't ever think this would happen. I thought I was gonna lose, and this wasn't meant to be, but for her [Coco] to be in our lives, it's more than I can put into words. I'm a very, very fortunate mommy.''
'X Factor' viewers have seen the playful and flirty relationship that Ayda, 39, and Robbie, 44, share and the actress insists that's how they are together all the time.
Ayda explained: ''The show, when you see it, is so short compared to what we film, and there are so many cheeky moments that are happening between us non-stop. For us, that's always been our language of love. We don't take ourselves too seriously. We're serious about how much we love each other, but we don't take ourselves too seriously.''
Robbie recently revealed that Coco - who has actually been named Colette Josephine Williams by her famous parents - is a lot ''more chilled'' than his other kids were as babies.
The 'Angels' singer - whose daughter Teddy was a bridesmaid at the wedding between Princess Eugenie and Jack Brooksbank in Windsor on Friday (12.10.18) - said: ''On the third one, you know, the kids are fighting, the TV is on and baby stays asleep and I think because we're more chilled, she's more chilled. 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.''
