The “Bombshell” star was spotted wearing a stylish one-piece swimsuit Saturday as she celebrated turning 46 while on vacation in Greece. Theron paired the fashionable look with a tan visor hat and matching black sunglasses.

The V-cut, all-black suit showed off the 5-foot-10 Oscar winner’s long legs as she spent time with family and friends.

Black appears to be the actress’ signature color as she also opted for the dark hue when wearing a tiny bikini on her trip days earlier.

Theron has been sailing the Aegean Sea aboard a lavish yacht with her loved ones to celebrate her birthday over the past week.

She shared on Instagram Saturday that her pals even threw her a prom-themed party since she never got to go to hers when she was younger.

“I love these humans more than words can describe,” the “Monster” star wrote alongside a picture of herself looking out to sea with a glass of white wine in her hand. “Only they could know that an 80s prom murder mystery party on a boat is my literal dream birthday. What a family, what a night.”

Theron also shared a second photo of herself, her daughters, Jackson and August, and her friends dressed in costume for the theme party.

In the pic, the A-lister appeared to wear an ’80s-style outfit, which prompted celebrity trainer Tracy Anderson to write, “Looks like a blast🎉 You are totally sporting super gorge Debbie Harry x Belinda Carlisle vibes here!!!!! Happy Birthday.”

Meanwhile, in the paparazzi photos of Theron, the “Sweet November” star was back to her more muted tones in the all-black swimsuit as she indulged in water sports.

She was seen on Jet Skis and on a flotation device with her children that whisked them all around the sea.

At one point, an employee on the yacht carefully placed a towel around Theron as she got back on board the mega-yacht. However, the movie star took matters into her own hands when hosing herself down after taking a dip.

In a few years, Theron will likely be joining the growing list of women in Hollywood who look fabulous in a swimsuit over 50. The mother of two previously told Harper’s Bazaar Australia that she stays fit by sticking to a plant-based diet and practicing pilates.

Happy birthday Theron! We wish you an everlasting happiness.
