Robbie Williams and his wife welcome a surprise third baby

Robbie Williams and his wife Ayda Field have been keeping a secret from their fans: they welcomed a new member to their family.

In an Instagram post shared earlier today, Field showed a photo taken of their hands and said: "I spy with my little eye and extra little hand."

The post received more than 78,000 likes and 5,700 comments in less than five hours. The adorable photo can be viewed below.

She explained that they welcomed Colette Josephine Williams, who is theirs biologically, via a surrogate during the early hours of the morning.

"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."

The family asked that their privacy be respected during this time, and she also included the hashtag "Team Williams."

Williams and Field feel strongly about their protecting their children's privacy and never share photos of their faces online.

In a previous interview, Williams explained that the press could not legally publish pictures of children in papers unless they are posting faces.

The couple also shares daughter Theodora "Teddy" Rose, who will turn six on September 18, and Charlton "Charlie" Valentine, who will celebrate his 4th birthday in October.

In an interview with "This Morning" back in June, Williams joked that he broke his only two commandments for life. He explained:

"I had two commandments, 'Thou shall not get married' and 'Thou shall not have children.' Then Ayda happened to me and all that changed."

He added that God laughs at the plans you might make and here he is today married to a "wonderful woman" and he wouldn't change it for anything in the world.

Williams also made headlines earlier this year when it appeared that he had a picture of his own face tattooed on his chest. But there was more to the story, read about it here.
