They followed it with a snap of Sam cuddling his daughter as she peeked over his shoulder, and wrote: "@bransonsam Eva-Deia already feeling protected by her daddy. @belliebranson."

Branson later posted a lengthy message about the new member of the family, writing: "Delighted to share the wonderful news that Isabella and Sam are the proud parents of a new baby girl: Eva-Deia Branson. She was born at 4.39pm on February 19th, weighing 7.14oz.

"Joan and I are the luckiest grandparents alive to have three beautiful healthy grandkids in the space of two months, and Bellie’s parents Mary Gaye and Jo are equally ecstatic."

He added: "I was in the British Virgin Islands and had an instinct to catch the plane back to London, although the baby could have arrived any time in the next week.

"Joan and I were lucky enough to get to the hospital before the birth, and within a few hours of my landing, Eva-Deia arrived.

"It was a magical moment watching Bellie and Sam welcome their child into the world; I’ve never seen them look happier and Sam was jumping for joy. They decided to name the baby after Sam’s grandmother Eve, and one of the most beautiful villages in the world, Deia in Majorca.

"We spent many happy times there as a family at our little hotel La Residencia, and funnily enough Holly also loved the name before deciding upon the equally beautiful Etta and Artie. Perfect names for perfect babies!"
