Simon Cowell, Susan Boyle

Simon Cowell says he was not surprised Susan Boyle got a mini-makeover — but he could care less about it.

"First of all, she's a woman. Here's somebody who's now one of the most famous people in the world, with a lot of people saying, 'You don't look very good,'" Cowell tells Extra. "I just want her to take this opportunity, sing fantastically and make the most of the biggest opportunity she's been given in her life. And I genuinely don't care about how she looks."

Boyle emerged Friday with dyed brown hair, tweezed eyebrows, a leather jacket and a Burberry scarf, looking far different than she did in her dowdy Britain's Got Talent debut.

"She's like me... improving with her looks every day," says Talent judge Piers Morgan. "What woman in the world, if you go from anonymity to becoming the most photographed person on the planet, wouldn't go and have a new haircut?"

Morgan doesn't think Boyle's new look will have an adverse affect — for now. "As long as there's no plastic surgery and no Simon Cowell teeth, then I think we'll all be comfortable with it."
