Transformation

She has experimented with bright blue shadow and has briefly gone brunet, but Gwyneth Paltrow is most famous for rocking long, pin-straight hair. "For a blonde, she has the thickest, healthiest hair," says stylist David Babaii. "She'll cut it and it will grow back in no time." Makeup artist Pati Dubroff says the star likes her skin sheer and favors balm over gloss and lipstick. "Her lips are naturally rosy, so they don't need much to pop." When the mother of two isn't scribing weekly updates to her lifestyle site, GOOP.com, or rocking out on Glee, she can be found in bookstores everywhere with her cookbook, My Father's Daughter.

"When I look back at pictures of me in high school," Paltrow has said, "I was sort of a minimalist. I never went through the big-hair-and-makeup phase."
