MARY J. BLIGE

Hair
Hairstylist Porsche Waldo adds extensions to create a "wispy, long, layered look."

Makeup
Blige's makeup artist Billy B says he uses "caramelly, soft colors" to keep her look natural "and to let her real beauty show without all the artifice."

Body
Thrice-weekly workouts with a trainer have trimmed down Blige's waist and strengthened her back. The diva also follows a low-sodium diet.

Clothes
"I try to make her more clean now, more amazing," says Blige's stylist Atiba Newsome. "She's a 'cute top' kind of girl. And I can put her in any color because her skin tone just works with everything."

JEWEL

Hair
Jessica Paster, Jewel's longtime stylist, says that these days the singer's formerly super-straight hair "is a little more sassy."

Makeup
"Before, her look was sporty and I'd use earth tones on her," Jewel's makeup artist Charlie Green told IN STYLE. "Now I punch up her features with color."

Clothes
"I just think that she's decided to have a little more fun with her wardrobe and take a few more risks," says Paster. "As you get older, you get so much more comfortable."

Shoes
"She's always loved shoes," Paster says. "She has always worn Jimmy Choo and Manolo Blahnik. Before, it was more boots. Now things are a little sexier, a little strappier."

CLAY AIKEN

Hair
"I looked like Opie," says Aiken of his pre-American Idol self. A dye job and a flatiron made his do less dorky.

Eyes
His green eyes got better exposure when he traded in his glasses for contacts.

Clothes
Clay was "a bit geeky," says AI stylist Miles Siggins, who gave him a cooler edge.

Shoes
Aiken learned from Siggins that you can make a suit hipper by wearing sneakers.
