Louis Walsh is quitting X Factor next year, he revealed last night. Walsh says he wants to concentrate on managing Westlife and former X Factor winner Shayne Ward. The Irishman, 55,said last night: "I will do one more series. I have really enjoyed doing it but Im not a TV star, Im a band manager. X Factor takes over your life. By the end of the final show I am exhausted, and then I have to work with my acts." He said he was close to fellow judges Sharon Osbourne and Simon Cowell but added: "Im not like Simon, I dont have to be on television or be a judge the whole time."
