Heather Graham, 51, Struts Her Stuff In Black Bikini

The amount of confidence Graham displayed on her makeshift runway was reminiscent of her appearance in the 1999 music video for Lenny Kravitz's sexy cover of the 1970 Guess Who classic "American Woman." She certainly didn't look like she had aged a day since she writhed around on top of a bus while wearing a sheer red shirt and bra. 

The Boogie Nights bombshell had on a classic black bikini with adjustable triangle cups and a wide halter neck to support her iconic ample assets.   

Graham's bottoms boasted a low-rise style that accentuated the curves of her hips while lengthening her toned torso. A sea breeze blew her beachy waves to the side as she sashayed toward the camera. She looked fierce and fabulous while tossing her hair around and spinning on the dock. 

In her caption, she revealed that her video was filmed during a girls' trip. 

"So grateful for my amazing girlfriends for making me feel good about myself and special," she wrote. 

Graham tagged gal pals Nina Bergman and Debra J. Fisher.

Graham revealed one thing she does to stay in such amazing shape in another recent Instagram post that showed her doing yoga with Bergman. The two women had their backs to some beautiful beach scenery, including crystal-clear water and shady palm trees. 

While tropical getaways and fruity cocktails go hand-in-hand, Graham told Us Weekly that she doesn't drink alcohol. She also stated that her "idea of a perfect vacation is doing yoga for four hours a day on a beach somewhere beautiful." Her other health secrets include swimming in the ocean, getting plenty of sleep, dancing around her house, and keeping the temperature inside her home "boiling hot all year round."

Graham's Instagram post attracted tons of attention from fans who deemed her a "goddess" and compared her to fine wine. 

"How are you getting more attractive as you get older?" wrote one of her followers in the comments section.

"Still hot as ever," another added. 

Those who want to see more of Graham will soon get their wish. According to Deadline, one of her latest projects is the Western film The Last Son of Isaac LeMay. Graham plays the mother of Machine Gun Kelly's cowboy character, as unbelievable as that may seem.
