Robbie Williams and his wife Ayda Field Williams have surprised fans by announcing they have had a baby boy via a surrogate.
Field Williams, 40, revealed the birth of their fourth child, Beau Benedict Enthoven Williams, on Instagram on Friday.
With a picture of their three other children's feet, plus the baby's, the actress wrote: "Spot the difference...
"On this Valentine's Day, we would like to celebrate love in the most awesome way... Beau Benedict Enthoven Williams.
"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."
The couple welcomed daughter Colette "Coco" Josephine Williams 17 months ago via the same surrogate.
When she was born, Field Williams revealed they had difficulties conceiving after their second child so turned to a surrogate.
She and pop star Williams married a decade ago and also have seven-year-old daughter Theodora Rose, known as Teddy, and five-year-old son Charlton Valentine, known as Charlie.
Williams turned 46 the day before they revealed their newest addition.
