Alicia Silverstone turned heads at the 82nd Venice International Film Festival on Sunday.

The 48-year-old Clueless icon — who recently revealed the shocking secret to her youthful looks — wowed in a strapless black mini dress.

The chic frock boasted a ruffled, floral-inspired skirt that cropped just above her knees.

Alicia rounded out her fashion-forward ensemble with a pair of pale pink heels with black bow accents.

Her signature silky blonde locks were arranged in sultry waves that framed her face and flowed down her back.

She looked effortlessly sleek with a baby pink manicure on her natural nails and elegant jewelry including a statement ring, diamond tennis bracelet, subtle diamond choker, drop earrings. 

While some of her Hollywood counterparts have turned to facelifts and cosmetic procedures to slow the aging process, Alicia has maintained her natural beauty.

She recently shared the key to her timeless looks has nothing to do with plastic surgery, Botox or fillers.

Instead, the actress attributes her plant-based diet to her youthful appearance.

She said her diet helped resolve multiple health issues that she had been facing since childhood.

'I ditched my asthma inhaler, I ditched my allergy shots [and] my skin cleared up. I lost weight, I had more energy,' she detailed on SiriusXM's Sam Roberts Show.

'It changed my life. I was no longer on medication — I was on a lot of medications as a kid,' she continued.

'It was great to be free from all that and it was just from my food,' she reiterated.

In early August she told Business Insider that she's never had Botox or fillers, nor has she gone under the knife.

The silver screen siren noted that her plant-based diet eliminated her acne and has had a host of other physical benefits she wasn't expecting.

'I could think clearly, feel more, be present. All of a sudden, my nails got really thick and strong. My hair got really thick. My eyes got all white,' she gushed.

'As I age, I'm aware that I don't look like everybody else. But I don't lose sleep over it,' she added.

Alicia has built a wellness brand with two bestselling cookbooks as well as a website, The Kind Life.

In 2018, at age 41, she said people often tell her that she looks the same as she did when she was a teenager in the 90s film Clueless.

'It's no accident that everyone says to me all the time that I still look like I did in Clueless,' she told RedBook at the time. 'I see the difference if I eat a certain way for a day, so I choose to make more than one meal be that great meal.'

She released her first book, The Kind Diet, in 2009.
