Heather Graham, 55, beats the heat in tiny red bikini during beach day in Sardinia

Heather Graham looked half her age in a bright red bikini while enjoying a beach day in Sardinia on Friday.

In photos from her carefree Italian vacation, the “Boogie Nights” actress, 55, wiped the water from her face while emerging from a dip in the ocean in the tiny two-piece.

Graham was also photographed navigating the aqua blue waters during a relaxing swim and wading in the surf.

Eventually, Graham made her way to the beach, where she adjusted a lounge chair.

Later, the sun-dried actress was also seen slipping into a pink set of coverall shorts and a white sunhat.

The “Austin Powers: The Spy Who Shagged Me” star is known for frequently sharing bikini pics via Instagram.

In December, she took to the platform in a bold blue string bikini, which she wore while relaxing in a hot tub in snowy Jackson, Wyoming.

Prior to that, the “Lost In Space” beauty modeled patriotic white and red bikinis from the deck of a boat to celebrate the Fourth of July 2024.

“Went to the @mediterranefilmfestival and got to see beautiful Malta! 🇲🇹 🥰🙏🏻 Wishing everyone a very happy 4th of July and sending you all lots of love! 🇺🇸🎇❤️💋,” she captioned the smoldering pics.

In an April interview, Graham spoke out about how she stays in shape.

 “I like going on yoga retreats because, to be honest, I love just being by the ocean,” she told People.

“So, anytime I’m at the ocean, I just feel happier.”

The “Hangover” actress also shared that she doesn’t follow a strict beauty or fitness regimen as she ages.

“I just enjoy the simple things in life — like sleeping, eating, my friends, things like that. I love meditating,” she told the outlet at the time.

Graham added, “I like to go out in nature, go to the beach, look at the ocean, go on a hike, go into the mountains, look at the trees.”
