Cowell: Westlife were ugly and I should have signed the Spice Girls

Simon Cowell's biggest regret is failing to sign the 'Spice Girls' to his record label.

The 54-year-old music mogul admitted that he was "hurt" when the platinum-selling girl band - made up of Victoria Beckham, Mel C, Mel B, Emma Bunton and Geri Halliwell - found worldwide success after choosing a rival record label and has regretted missing out on the chance to work with the 'Wannabe' singers ever since.
