Simon Cowell was very impressed by Susan Boyle’s performance on America’s Got Talent last week, saying that she was ‘staggeringly good.’

The Britain’s Got Talent judge told The Mirror:

“I thought her performance was staggeringly good and I felt amazingly proud of her. It hasn’t been easy for her as we all know.

“It was a personal triumph and I was very very happy for her.

“I am really happy with the record and I am going to say that it will be the biggest album of the year.

“She has a broad reach of fans so we have made an album to appeal to that.”
