Thirty-five-year-old British-born Naomi was raised in Australia and worked regularly in small roles until her big break came in 2001 in David Lynch's Cannes Film Festival prize-winner Mulholland Drive.
Since then she has made nine movies, including her Oscar-nominated 21 Grams. We'll see her next in We Don't Live Here Anymore in which an indiscretion between two close friends tears down their respective marriages.
FRAMEWORK
The blonde beauty is 5ft 5in and was named one of the 50 Most beautiful People by People Magazine in 2002. She says: "Instead of thinking 'How can I slow the ageing process?' I think 'How can I bend the rules.'" Plastic surgery? "I think it would be a shame if I did, but I'll never say never. I look at all those actresses who have had plastic surgery and they don't look any younger - just a bit stranger. But look at Meryl Streep or Susan Sarandon - they just look like beautiful, older women, and I hope I'm able to be like them." She says she never became aware of her body or looks until she was in her early twenties. "I wasn't a 'girlie girl', but a tomboy. Grooming and that kind of stuff never entered into it. I never had pretty pink nail polish on or pretty pink dresses."
She admits she's not into grunt workouts, preferring to keep her figure in shape by low-maintenance routines, like taking her dog for long walks and gardening.
DIET
She is a vegetarian and puts that down to her always staying in trim. Among her favourites she lists baked beans! "I grew up on them. There were times when it was all I could afford. Now I can afford caviar, but you won't see me eating it. Baked beans turns me on a lot more." She says she has the occasional cigarette when she's feeling peckish, but it's not a strong habit and she can easily stop for weeks at a time. One thing she will never give up? Chocolate cupcakes.
LOVE-LIFE
Her on-off-on-off relationship with Heath Ledger - whom she met when they co-starred in Ned Kelly -- seems to be on again. He accompanied her to this year's Oscar ceremony. She is on record as saying she cannot ignore her ticking biological clock much longer.
"My mother wants me to have children and, frankly, I've been dying for it since I was 19 but I hadn't met the right man." Until now?
