The estranged father of Oasis rockers Liam and Noel Gallagher has confirmed press reports that the musicians have a secret sister. Tommy Gallaher was married to Liam and Noel's mother Peggy when he fathered a love child, Emma Davies, who was born only 11 months after Liam in 1973. The 62-year-old says, "Yes, it's true. I'm her dad and I'm happy to say so." The Wondewall hitmakers have refused to have any contact with their father since he divorced their mother in 1986.
