Say it ain't so, Susan!

Singing sensation Susan Boyle -- whose dowdy image contrasted so greatly with her angelic voice that she became an instant Internet celebrity -- has gone in for a makeover.

Boyle, 47, had her graying, frizzy hair dyed chestnut brown and styled in what The Sun tabloid says was a 35-pound ($50) makeover. And instead of the old-fashioned dress she wore on the TV show "Britain's Got Talent," the Scottish singer was photographed wearing a stylish black leather jacket with what looked to be a Burberry scarf.

Asked if she would change her looks on CNN's Larry King Live, Boyle replied "Why should I change?"

Judges of "Britain's Got Talent" will decide whether Boyle gets through to the next round on May 23.
