"I was talking to Simon Cowell last night about it," Piers told Access Hollywood on Monday. "We were both saying, in all our careers and the various things we have been involved with — big stuff — we can never remember quite the phenomenon that this year's 'Britain's Got Talent' has been… It's been crazy."
But she also captured the hearts of people everywhere with her rendition of "I Dreamed A Dream" from the musical "Les Miserables," back in April – a performance that garnered over 100 million YouTube views.
"She's gone from anonymity — completely unknown — to becoming one of the most famous women on the planet in several weeks," Piers said of Susan's instant fame.
In the run up to the final, which was held this past Saturday, several reports came out in the British tabloids alleging that Susan lashed out verbally at two reporters and a policeman.
Piers previously told Access that in the wake of the headlines, Susan considered quitting the show, but she put it all to the back of her mind over the weekend and put in a performance that Piers said was remarkable.
"To go on that stage with all the world's pressure on her shoulders… and perform like that on Saturday? I thought it was incredible," Piers said.
Despite all of her efforts, Susan was upset at the final show by dance group Diversity.
However according to Piers, this is not the end of the road for Susan.
"The sky's the limit for Susan," he said. "It's been one of the most extraordinary stories I have ever been involved with — and she's a delightful lady."
