Writing on the social networking site, the Irish businessman wrote: 'My beautiful wife @wonderwomanshel gave birth to our gorgeous baby girl 'Faith Michelle Hanley' yesterday morning. Circle of life is amazing.'
Despite playing doting mother to her newborn, the Liberty X star found time to retweet the message to her 60,000 followers.
Michelle, 31, was married once before to Andy Scott-Lee for two years; but the pair split in June 2008 without ever having children. Later that year she met Hugh and last July they said 'I do' in the Bahamas.
Michelle's good friend Katie Price will be Faith's godmother; after she was asked to fulfill the special role last month at the baby shower.
Mother-of-three Katie took to her Twitter page to say: 'I'm sooooo happy and over the moon that @wonderwomanshel and @hughhanley have asked me to be a godmother to there (sic) baby. Woo forever friends.'
Michelle Heaton has given birth to her first child; a baby girl called Faith. Her husband, Hugh Hanley, proudly posted a message on Twitter today, revealing they welcomed their new addition to the family yesterday.
