Robbie William's wife Ayda Field pays heartwarming tribute to their son on his first birthday

It's hard to believe, but it has already been a year since Robbie Williams and his wife, Ayda Field, welcomed their fourth child into the world.

In honour of the youngster's first birthday, the singer's wife took to social media to share a photo of the 'Angels' hitmaker holding Beau while surrounded by blue, white and silver balloons in front of a snowy mountain scene.

Alongside the snap - which was taken at their new home in Switzerland - she wrote: "@robbiewilliams face after I told him I wanted 1 more baby...

"Beau...We dreamed about you for years before we finally met you, exactly one year ago today.

"From the seed of our hopes, to the smiling, gorgeous boy we are blessed enough to love today, you have been our miracle, the total completion of our family, and the best thing to come out of 2020," she continued.

"Thank you for answering our call to The Universe...we love you with all our hearts combined. HAPPY FIRST BIRTHDAY BEAU ❤️ Mummy, Daddy, Teddy, Charlie and Coco xxxx."

More of the birthday celebrations were seen on Field's Instagram Story as she posted further pictures of the impressive balloon displays and a handwritten message from Williams to his son.

The couple surprised fans last February when they announced the birth of Beau Benedict Enthoven, who was born via the same surrogate who carried their daughter Coco, on Valentine's Day.

They are also parents to daughter Teddy, eight, and six-year-old son Charlton.
