Robbie Williams has become a Father this afternoon as his wife Ayda Field gave birth to a healthy baby girl.
The couple has named their newborn Theodora Rose after she was delivered this afternoon at London's Portland Hospital.
Robbie took to Twitter with a link to his blog, announcing the news of the baby's birth earlier this evening.
He posted: "Praise be, it's Theodora Rose Williams, affectionately known as Teddy..... Born 3.33pm on 18.9.12, 7Ibs 4OZ"

The Sun reports that Ayda went into labor last night, with a source revealing to the paper that Rob was present throughout the birth.
They said: "Robbie was at Ayda's side throughout — she did so well."
"They are spending their first night together as a happy family."
The couple, who have been married for two years, announced the pregnancy in March.
However, Theodora arrived eight days earlier than the couple had anticipated with the two previously announcing that she was due September 26.
Robbie Williams is currently embarking on his solo career comeback, with new single 'Candy' due to be released on October 29.
Until then, we're sure Rob will be more than happy to swap his new material for nursery rhymes.
