Transformation

Beyonce's mirror apparently has two faces: Beyonce Knowles and Sasha Fierce. "I love that there are two sides to her," says makeup artist Mally Roncal. "One is the natural side, which is about her being real and not wearing much makeup. Then there's her adventurous side, where I can put strong green shadows on her eyes and fuchsia or orange on her lips. Beyonce's got such incredible skin tone; she looks great in every color of the rainbow." And when it comes to her full mane, the singer loves to let loose. "She likes the feeling of it being big, long and free-flowing," says hairstylist Kimberly Kimble.

1998: The Destiny's Child lead took beauty cues from her mother: "She made sure we had our lip gloss or blush in our purses. She made us pay attention to the details."
