AnnaLynne McCord's Changing Looks

The 20-year-old Nip/Tuck actress's swept-back chignon and coral lips showed style savvy beyond her years. "This look has a very chic, almost Sharon Stone vibe to it," says her makeup artist Gregory Arlt. "Very adult and sophisticated."

AnnaLynne embraced her natural spirals. "It took me a long time to find peace with my hair, but someone turned me on to using products that contain sea salt," she told InStyle. "It helps control the curls."

"This is a retro glam look that really brings out her gorgeous eyes and skin," Arlt says of 90210 star at the People's Choice Awards. "Annalynne and I both love the '40s and wanted to do a modern take on the look."

For the Young Hollywood Awards, stylist Steve Mason gave McCord '50s-inspired barrel curls.

"I love this look, from her defined eyes to her sweet, pink lip color," says Arlt. A curly, low-key updo complemented the romantic vibe.

McCord channeled Farrah Fawcett's swoopy layers and barely-there makeup at New York Fashion Week.

The actress amped up the drama with pin-straight strands and faux lashes.

McCord made a surprising switch to brunet locks.

McCord accentuated her features with deep rose lipstick and shimmery white shadow.

Making a dramatic return to darker hair, McCord chose a smoky eye and natural curls for the Art of Van Cleef & Arpels event in California.

Back to blonde, the actress complemented her tousled curls with winged-out liner and a fiery red lip.

McCord sported gentle waves and natural makeup for the Sports Spectacular Luncheon in Beverly Hills.
