Heather Graham, 55, stuns in revealing bikini during beach outing

Heather Graham sent temperatures soaring during a sizzling beach outing in Sardinia on Friday.

The Austin Powers bombshell, 55, looked half her age as she flaunted her flawless figure and youthful glow while frolicking in the surf and sand of the Mediterranean hotspot.

Rocking a skimpy red two-piece, the ageless beauty channeled her iconic Boogie Nights days—looking like she hadn’t aged a day since playing sexy Roller Girl back in 1997.

At one point, she dove into the crystal-clear water like she was posing for a swimsuit calendar shoot. 

Later, she slipped on a wide-brimmed sunhat and showed off her pert derriere while lounging in the sand.

Graham’s sun-soaked getaway comes just months after she set the internet ablaze with envy by sharing photos from a luxe yoga retreat at Souk Studio in Tulum, Mexico.

The images showed the Wisconsin native, who is the daughter of a retired FBI agent and children’s books author, posing in various string bikinis on her spiritual getaway.

‘You look [fire emojis],’ one fan commented under the post. 

Another gushed: ‘My every day crush for 20 years running and still as spectacular as the first time I laid eyes upon her.’ 

Other raved that she ‘hasn’t aged a day’ and looked ‘beautiful.’ 

Over the years, she shared a few tricks to her age-defying looks, including her ‘obsession’ with yoga, sugar-free diet and up to 12 hours of sleep a night. 

‘I’m obsessed with yoga,’ she also told Refinery29 previously. ‘For fun, I would go on a yoga retreat and do four hours of yoga a day. Then I do Pilates.’ 

During that interview, she also insisted that her restrictive diet just makes her ‘feel a lot better.’ 

‘I do eat sugar sometimes, but as a broad rule, I try to just eat no sugar basically,’ she explained. ‘And I will sometimes eat things with white flour, but I try to avoid white flour.’

Similarly, the actress told The Independent in 2013 that she had largely stopped consuming alcohol, adding: ‘I’m kind of goofy enough to have fun without drinking.’ 

In 2016, she told The Guardian that getting some serious shut eye was her ‘guilty pleasure’ and that most people are ‘horrified’ to learn she rests ‘nine and 12 hours a night.’

Sleep is often considered a natural way to combat signs of ageing such as wrinkles and sagging because this is when new collagen is produced. 

Graham was also keen to stress that once a week she ‘spends a day luxuriating in bed.’ 

Her other tricks include moisturizing her ‘whole body’ and face and getting massages. 

The sultry snaps come after Graham called out sexism in Hollywood and in society in a recent interview.

‘I think, culturally, there is definitely a message out there that keeps telling us, “Women feel bad about yourself!”‘ she explained to NewBeauty magazine.

Graham went on to add: ‘It seems like there’s no age where we’re really allowed to feel good about ourselves – except for maybe a very short window.’

‘The rest of the time we’re supposed to feel like, “I’m too young or I’m too old,”‘ she said.

But, the Austin Powers star has found a way to deal with the frustration and remain happy and peaceful.

‘I have to unplug from the culture, which is a patriarchal way of looking at things, and to affirm myself and be happy and grateful for what I do have,’ she revealed.

‘The older I get, the pickier I am about the energy I want around me,’ the Scrubs alum told the outlet.

‘I want loving, supportive people by my side. When I was younger, I was always seeking out the difficult, dramatic, complicated people. At some point, I realized that is exhausting.’

Age has brought wisdom and clarity to the Extrapolations actress.

‘Now, I try to have people that are supportive in my circle… You have to be with the people that really celebrate you.’

The performer achieved widespread fame after landing her role as Rollergirl in the 1997 cult classic Boogie Nights. 

Her other most notable film credits include From Hell, Bowfinger, The Hangover, Judy Moody and the Not Bummer Summer, The Rest of Us, and On a Wing and a Prayer. 

She’s also appeared on the TV series, Scrubs, Californication, Twin Peaks: The Return, and The Last Son.
