In less than three months, Nicole Kidman will turn 50. Yep — the big 5-0. And after five decades on this earth, you'd think we'd be turning to the actress for tips on under-eye cream and the like. Not so much: We want to know just what the leggy, sometimes-blonde bombshell is doing to stay in such damn fine shape. Here's everything we found out.

She eats lean protein.

Like any good Australian, Kidman's a big fan of food that comes from the ocean. She told Food&Wine her favorite Australian dish is "a fresh seafood platter with Sydney rock oysters, tiger prawns, mudcrab, and lobster." The protein-rich shellfish can be expensive, but cheaper options, like tilapia or even canned tuna, have little fat and few calories.

She believes in eating anything she wants — in moderation.

"I'm just not someone that believes in denial," Kidman told Women's Health. She aims to eat healthy 80% of the time, leaving 20% open to cheat foods … like the junk stuff that's always on her husband Keith Urban's tour bus.

Kidman supplements with vitamins.

Diet guidelines can be overwhelming. You have to hit a certain amount of protein while keeping fat and calories down — and oh, you can't eat anything on this list of 100 foods. It can be difficult to check off the boxes, so Kidman — who's often traveling, which makes healthy eating even more difficult — takes a daily multivitamin. It "helps fill any nutrition gaps," she told Los Angeles Times. Her go-to brand is Swisse.

Her coffee order is super strange.

"I love the foam more than the coffee," Kidman told People. When she puts her order in at her local Starbucks, she asks the baristas to make it all foam and very little coffee. Strange, but maybe she's onto something: The foam takes up the room that coffee (which you might be tempted to load up with sugar and cream) otherwise would!

She knows the power of a great workout playlist.

Kidman revealed an unlikely favorite song to Women's Health: Britney Spears' "Work Bitch." She'll mix in anything old-school, too. "I love 'Sweet Child O' Mine.'," she's said.

Kidman varies her exercise routine.

The Aussie actress's father was a marathon runner, so a love of jogging runs through her veins. Rather than grow bored on a treadmill, though, she prefers to run in the woods when she's home in Nashville. "And in Sydney you've got the beach, which is absolutely beautiful to run on," Kidman told Women's Health. Beyond that, she's tried organized sports, yoga, and spin, telling Los Angeles Times of the latter, "I try to get everyone to spin."
