Susan, 48, came second in the British version of the show but shot to fame around the world after her first audition.

A new series of America’s Got Talent has recently started, and Piers said he believes the show will have more viewers than ever before.

He said: "I mean, look, the British show got record ratings up 50% because of the Susan Boyle phenomenon. And I have got no doubt that we are going to see significant increases in the ratings of America’s Got Talent this summer.

"I think this season we’re back where we should be as the number one summer show, and we’ve got this incredible oxygen of the Susan Boyle phenomenon and all the interest around Britain’s Got Talent."

Piers admitted he believes people will enter the show to try and "beat" Susan Boyle’s success.

He said: "I think Americans are very competitive particularly when it comes to the Brits and I think that America’s going to want to tune in to see how America responds to the challenge, you know? Have you got anyone who can beat our Susan?"
