• Charlize Theron was photographed in a black bikini aboard a yacht in Greece Tuesday
  • The trip was a family affair as Theron's mom and two daughters were also present
  • The "Mad Max" star also shared a video of her and her two daughters jumping off the yacht's railing together

Charlize Theron is having a blast with her family on their Greece getaway.

In photos obtained by Page Six, the "Mad Max" star showed off her toned figure in a black string bikini while aboard a yacht off Paros Island Tuesday. She paired her swimwear with dark shades.

Theron was joined by her daughters Jackson, 9, and August, 5, on the trip. The actress and her kids were also spotted with a mystery man with reddish short hair and striped swimming trunks. He joined the trio on an inflatable ride in the Aegean sea.

Also present on the boat were Theron's mom, Gerda Maritz, and a few other pals, including three men.

At one point, Theron was seen taking a brief break from swimming and drinking what appeared to be coffee or tea.

Page Six has not received a response for requests for comment from Theron.

However, the Oscar winner did share some highlights from their Greece vacation when she recently posted a rare video of her with her two girls on Instagram. In the video, the trio can be seen jumping off the yacht's railing together, with Theron holding their hands.

"Me and my girls 4 life [purple heart emoji]," she wrote in the caption.

Theron's followers and fellow celebrities showered her and her daughters with love in the comments of the video.

"I love this. And you three," Mary McCormack commented.

"Epic," Reese Witherspoon wrote with dizzy emoji.

"Love how you held hands all the way down," Helena commented.

"LOVE this so much," Tan France wrote.

"Love this!! Looks so inviting!" Sean Hayes added with a red heart emoji.

Theron rarely shares photos and clips of her children, both of whom she adopted. But last year, a week after Mother's Day, she posted a snap of her cuddling her daughter Jackson on the set of "Mad Max."

“I became a mom right before we started shooting. At least my child will forever have the fun fact of 'I spent most of the first year of my life in a war rig' (special appearance by my incredible costumer Inge Hough),” Theron wrote in the caption.

It's unclear if she has already moved on from her last ex, Sean Penn. However, the "Monster" actress said last year that she told her daughters she was dating herself after they encouraged her to find a new boyfriend.

"Two days ago I was in the car with my two girls and my little one said something like 'You need a boyfriend!'" Theron said on Diane Von Furstenberg’s Spotify podcast "InCharge with DVF." "And I said, 'Actually, I don't. Right now, I feel really good,' and she's like, 'You know what, mom? You just need a boyfriend, you need a relationship!'"

"She had this look in her eye like she had never really contemplated that that was even a possibility," she said. "Her mind was blown. But, I know that was the day that she realized there's a different possibility."
