London, April 19 : Britain's Got Talent's unique finding Susan Boyle could become a millionaire overnight if she gets a record deal, says X-Factor judge Louis Walsh.

Walsh said that if the 47-year-old church volunteer from Scotland gets a record deal she would shoot straight to number one in America.

"I''ve never seen anything like this. Middle America obviously loves her," Sky News quoted him as saying.

"With the kind of support she''s getting she could easily have a number one album.

"And if she had a successful tour then she could make millions," he added.

Boyle''s jaw-dropping performance of the Les Misérables song `I Dreamed a Dream' on the ITV talent show has so far attracted 25 million YouTube hits. (ANI)
