Ex-boyzone manager Louis Walsh says singer Nadine Coyle would have had a successful solo career had she married a famous footballer just like her Girls Aloud bandmate Cheryl Cole. Cheryl was married to footballer Ashley Cole for four years before ending their marriage in 2010. “But she (Nadine) didn’t marry a footballer. If she’d married a footballer she’d have been a big star,” The Gaurdian magazine quoted Walsh as saying. Walsh is currently seen as a judge on reality show “The X Factor”.
