Simon Cowell has admitted that he was a bundle of nerves when he brought his Got Talent show to American audiences.
Cowell, famed for his screen confidence, revealed that he had no idea how audiences would react to his talent search show, given that they'd only known him as the mean no nonsense judge on American Idol.
Cowell, speaking before the launch of the 18th season of the hit NBC series, confessed that his first day on AGT was reminiscent to attending school for the first time.
