British pop star Robbie Williams has become father to a baby girl, the singer has announced. Williams, 38, announced the birth of his first child on his blog, where he wrote: \"Praise be, it\'s Theodora Rose Williams, affectionately known as Teddy..... Born 3.33pm on 18.9.12, 7Ibs 4OZ. \"Baby, Mummy and Daddy are all rockin.... Thank you for your best wishes XXXX.\" Congratulations have flooded in for the Take That singer and his wife, US actress Ayda Fields, with X Factor judge and former bandmate Gary Barlow tweeting: \"Massive congrats Rob and Ayde. So happy for you\". Williams had recently announced that he had a private jet on standby to ensure he did not miss the baby\'s birth as he toured other parts of Britain. It was not clear whether he had to use the jet or not. He also said that he wanted the baby to grow up in Britain rather than in the United States, where he and his wife currently live, saying that children in Los Angeles have a \"massive sense of entitlement\". \"I don\'t want to educate our baby in LA because I would much prefer her to have English sensibilities,\" he said. Williams first rose to fame as a member of 1990s boy band Take That, later becoming one of the UK\'s best-selling singers as a solo artist. He and Fields have been together for five years, marrying in 2010.
