Robbie Williams admits he and Ayda Field keep waiting for their surrogate baby Coco 'to be a nightmare'... but insist she's the 'most chilled' out of their three kids

Robbie Williams and his wife Ayda Field secretly welcomed their newborn daughter Coco via surrogate last month.

And now the former Take That star, 44, has opened up on life as a dad-of-three, revealing how there’s no jealousy between the siblings, 'just lots of love.'

The X Factor judge confessed to the Mirror that he and Ayda keep waiting for Coco 'to be a nightmare', but insisted that actually his youngest bundle of joy is the most chilled baby out of the bunch. 

Rather than panicking over noises disturbing the newborn, he said: '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.' 

And when asked how his other children have adapted to having a newborn around, he revealed: 'The kids, there’s no jealousy, there’s just lots of love.'

Ayda and Robbie, who have been married since 2010, are also parents to Theodora 'Teddy' Rose, six, and Charlton 'Charlie' Valentine, who turns four on October 27. 

When asked about what his two older children think of baby Coco, Robbie revealed: '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.' 

The doting father also admitted that, although Coco doesn't understand what a smile is, she is simply adorable and doesn't give him or Ayda any hassle. 

The pair announced the arrival of their 'very special secret' baby at the start of September in a surprise social media post, after welcoming her via a surrogate.

Alongside an adorable black and white snap of their hands, along with their new daughter's, the couple also spoke about their 'difficult' path to a third child to complete their brood.

In the post 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.' 

She continued: '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!'
