Jaclyn Smith, one of the reigning bombshells of the 1970s, still cut a youthful and luminous figure when she was seen this week aged 80.

She shot to stardom alongside Farrah Fawcett and Kate Jackson on the original Charlie's Angels series, which ran from 1976 to 1981.

In recent years she has repeatedly left fans agog with how exquisitely she has managed to maintain her radiant complexion and willowy figure.

Smith made yet another age-defying appearance as she surfaced in Beverly Hills, exuding the showbiz glamour for which she rose to fame.

Draping her lithe torso in a flowing striped white blouse, she emphasized her vertiginous legs in a set of fitted oyster jeans.

Her blonde locks fell in gentle waves to frame her screen siren features, which she accentuated with elegant makeup for her latest outing.

Smith accessorized with shades and a simple off-white handbag, rounding the look off with a comfortable set of sneakers well-suited to a brisk stroll.

The Houston-born actress was seen chatting busily on her cellphone as she dashed around the tony 90210 zip code during her day's business.

Smith achieved nationwide pinup status as Kelly Garrett on Charlie's Angels, and was the only one of the three leads to stay on the show throughout its run.

Post-Charlie's Angels, her acting gigs have largely been TV movies and miniseries, such as a Golden Globe-nominated turn in the title role of the 1981 ABC picture Jacqueline Bouvier Kennedy, with Rod Taylor featuring as her father.

She played Kelly Garrett again in 2003 for a cameo in Charlie's Angels: Full Throttle, the second in the film series starring Drew Barrymore, Lucy Liu and Cameron Diaz.

Smith most recently returned to the role for the 2019 flop Charlie's Angels movie starring Kristen Stewart and directed by Elizabeth Banks.

She has also made successful forays into designing, including with women's apparel for Kmart and a Jaclyn Smith Home and a wig collection.

Her first three marriages lasted less than a decade apiece, but the fourth, which is to a surgeon called Brad Allen, began in 1997 and has survived to this day.

In recent years, Smith's latest husband also developed a skincare line for her, amid gathering public fascination with how she has retained her beauty down the years.

She gave credit to her 'healthy lifestyle' in an interview on the subject a few years ago, remarking: 'I don’t drink. I’ve never touched a drug. I exercise daily. I’m married to a heart surgeon who preaches the importance of eating your fruits and vegetables. I enjoy my green drinks. What we put on our bodies shows up on our faces.' 

Her fridge contains 'lots of fruits and vegetables,' and 'I try to have a green drink made from my vegetables to stock up,' she told Fox News.

'But listen, I eat meat. I’m gonna have my hamburgers and I’m gonna have my pizza. I love cheese. I’ve gotta have my gummy bears. We gotta enjoy life,' she noted.

'I think having everything in moderation is so important. If you’re so strict, it’s going to show up on your personality and your face,' Smith observed.

'You will get a little angry for depriving yourself of so much. If you try too hard to be too strict, you will then splurge and it defeats the whole purpose. Everything in moderation is much more rewarding,' she said.

Her exercise regimen, meanwhile, includes 'Pilates and weights' with a trainer who 'keeps me motivated and challenges me,' she shared. 

'For me, movement is so important. I feel at a certain age, there’s always going to be some sort of bone loss. I’m also a breast cancer survivor. I did a lumpectomy 20 years ago with radiation and I went on a drug that can cause some bone loss,' she added.

'I also live with a man who loves working out and taking such good care of his body. He always says that exercise is as much for your bones as it is for your brain.'
