Simon Cowell has said he's looking for a new Amy Winehouse as this year's X Factor returns for its fifth series. The music mogul said he was looking for someone who was going to be an international star. He said: "I want someone who is going to represent this country all over the world for the next ten, 20 years - that's what I'm looking for. "I want somebody who is different and unique and I want to find somebody as good as Amy Winehouse - I'd love to do that." This year sees a new line-up featuring Girls Aloud star Cheryl Cole, who Cowell described as "a little fighter" and said she was there to bring honesty to the panel. But Cole said she would be looking to the other Girls Aloud members for advice. She said: "It will be difficult for me not to get too emotionally involved with my acts so that is when I will be relying heavily on their help and honest outsider opinions." Fellow judge Dannii Minogue said she and Cole were desperate to hear some new cool songs on the show. She said of Cole: "She is totally into urban music, so hopefully we can get a flavour of that on the show."
