ITV has assured X Factor boss Simon Cowell that it has enough money to do a revamp of the show as planned. “What we’re trying to do is make better shows than we’ve done before,” Cowell told the BBC. “If we can’t do that, there’s no point in doing it.” Filming on the US X Factor stars next March, which could mean moving the next Britain’s Got Talent series to Fall 2011. Cowell said that he was setting up a joint venture with new CNN host Piers Morgan for talk shows. “He’s a brilliant interviewer,” said Cowell. The X Factor boss also called Lou Reed “petty and pathetic” for not allowing Susan Boyle to perform his song Perfect Day on America’s Got Talent. Boyle arrived in Los Angeles yesterday hoping to sing the song, only to find permission had been refused. The X Factor impresario said he’d become bored of doing American Idol after 10 years “especially when you’re not producing it. I got fed up”.
