Naomi Watts's Changing Looks

Watts at the premiere of Dangerous Beauty. "I can assure you, I did my own hair and makeup," she told us of the low-key look. "My hair changes all the time, and this was a short haircut."

Busy filming her breakout role in David Lynch's Mulholland Dr., Watts wore a shaggy bob with chunky highlights: "I went to the salon for the color, and I think it'€™s looking a bit stripy here."

The actress sported sexy bedhead waves and natural makeup at her first Academy Awards appearance. "My hair looks really voluminous here, I was wearing a black dress that was sort of plain, so we wanted to be more dramatic with the hair," she told us. "It's very big and tousled. I know for the Oscars, the updo is usually popular, but we went for the kind of... je ne sais quoi."

Nominated for role in 21 Grams, the I Heart Huckabees beauty attended a pre-BAFTA party with a 'do by Sam McKnight. "It's elegant and swept away," she said. "It's not too severe, but has a little height and volume."

Watts took the lead in King Kong and worked '30s-inspired waves.

"This was more of a dramatic look," she said of her appearance at the Costume Institute Ball. "[Host] Thierry Mugler wanted kind of an Old Hollywood look with the red lips-it took a bit more time, but I loved it!"

Watts put together a seriously hot combo for a screening of The International-smoky eyes and sleek strands: "It was a very modern and chic look."

For the Cannes Film Festival premiere of Fair Game, Watts played up her natural beauty with a sleek center-part and whisper-soft makeup.

Watts brought the heat to the L.A. premiere of Salt with sexy long fringe. "I definitely feel good with straight, shiny hair," she said of the look. "We did bangs there too! That was near the end of the era when my hair was falling out, so I ended up just cutting bangs when my hair was going through that awkward growing-in phase."

Watts opted for a '60s-inspired updo for the London premiere of The Impossible.

"Naomi is one of those actresses who evoke a timeless, classic elegance," makeup artist Pati Dubroff said of her Golden Globes look. "I kept thinking Carole Lombard, and of the polish of the '30s screen sirens." To complement her finger-waved faux bob, Dubroff blended Chanel's Powder Blush in Rose Petale high onto Watts' cheeks, and used a mixture of plum and pewter tones like the Illusion D'Ombre shadow in Epatant on her eyes. The Rouge Allure Lip Color in Determinee was then pressed onto Watt's lips to create a light stain. "She was sexy and sultry, and that is how I see Naomi."
