American Idol judge Paula Abdul has defended British singer Lily Allen for cancelling a string of gigs in the U.S. The singer, 45, believes Allen is too talented to be criticised for cancelling her U.S tour after encountering visa problems - which left her unable to enter America. She says, "I love Lily Allen. I don't think the fact that she had to cancel her gigs in the States will necessarily affect her success here. Talent is talent. "People forget that pop stars are human, too - we don't want to let people down but sometimes we can't help it."
