Jada Pinkett Smith is one foxy 40-year-old!

The actress and singer showed off her fab figure over the weekend, posting a photo of herself in a string bikini on Twitter. In the picture, Jada — who will be 41 in September — is standing knee-deep in water, showing off her toned stomach and sculpted arms in a Missoni two-piece suit.

"To my Forty and over crew! Don't believe the hype…We DO get better with age!" she wrote to her nearly 240,000 Twitter followers.

Jada, who has been married to Will Smith since 1997, recently revealed her diet secret. "I don't eat for pleasure," she told Essence. "I probably had the only West Indian grandmother that could not cook [laughs]. She was an awful cook, and she taught me that you don't eat for taste, you eat for nourishment. And I have kept that over the years, so I can eat anything that's healthy. I eat for my schedule so I have to eat high-protein, lots of greens and healthy carbs so that I don't fall flat on my face."

As far as exercise, Jada has said she's been active her entire life, starting with horseback-riding lessons and dance classes as a girl. "Sitting at home on a Saturday or Sunday was never an option," she told Shape. These days, she works out five times a week — her favorite activities include boxing, martial arts, and yoga — and she and her husband make it a family affair, involving their kids, Trey, 19 (from Will's previous marriage), Jaden, 14, and Willow, 11. "They love to go to the gym with Will and me, but surfing and snowboarding is what we do together as a family for fun."

Well, it is definitely working.
