Ayda Field has given fans a glimpse of her newborn son in a video which shows husband Robbie Williams tenderly cradling the infant.
The couple broke the news of their fourth child's birth on Valentine's Day, after keeping his impending arrival secret as he was born to a surrogate.
In the clip, the Rock DJ singer is seen gazing down at his son, Beau Benedict Enthoven Williams.
"@robbiewilliams A Beau-tiful Moment #fatherandson #babybeau AWxx," Field captioned the video.
"How's it feel, Dada?" Field asks her husband in the clip as he playfully winks at the camera.
It's the pair's second child to be born with the help of a surrogate after they announced the surprise arrival of daughter Colette, known as Coco, in 2018.
Announcing his birth on Valentine's Day, Field wrote: "As with Coco, he is biologically ours, but born via our same incredible surrogate. We are so blessed to have our healthy son safely in our arms and are officially complete as a family #happyvalentinesday #surprise #familyof6 #whodathunkitinthe90s. The Williams Family xx."
After Coco's birth, Field explained how it had been a "long and difficult path" to welcoming their third child and that they were "eternally grateful" to their surrogate, whom they have never identified.
They also have two older children, daughter Teddy, seven, and son Charlton, five.
Before Beau's birth, Williams opened up on his parenting style when is comes to his offspring, noting that he is "strict" when it comes to their manners.
He said he "only pretends to be arrogant" and wouldn't stand for such an attitude in his own children.
"Pomposity, arrogance and ill manners just make my skin crawl, and any sign of that with my kids, I do come down like a ton of bricks,” he said.
