Actress famed for iconic sexy beach scene in late 70s goes virtually unnoticed while shopping in California - can you guess who it is?

It has been forty-five years since she shot to fame running down a Mexican beach sporting a dark golden tan, wearing a shimmering gold one-piece bathing suit and her hair in beaded cornrows.

Only 23 years old at the time, she was heralded by fans and the media around the world as the 'perfect woman,' with her high cheekbones, symmetrical face, sky-blue eyes, and stunning figure.

Almost five decades later, the petite blonde, donning a green flowered blouse, white linen pants and canvas sneakers, and dark sunglasses, went completely unnoticed as she patiently waiting for her salad at Field + Fort café in Summerland, California. 

Can you guess who it is?  

Still as gorgeous as ever at 67, Hollywood veteran Bo Derek appeared to relish her anonymity.

She observed as other customers stood in line near her to order their food, smiling at their dogs, and seemed to enjoy just people watching.

Bo was what Summerland and Montecito locals call an 'extreme heat refugee' from the nearby Santa Ynez Valley where she lives with second husband John Corbett, 63, on a 10.5 acre ranch.

On the day, temperatures in Santa Ynez reached a stifling 109F degrees, so it's no wonder she and a girlfriend hopped in her car and headed 36 miles south to Summerland, which sits along the coast just south of Montecito and is at least 25-30 degrees cooler in the summer.

'Ah, I just love that ocean breeze', Bo was overheard telling her friend and lifting her famous face up to take a deep breath.

After lunch the two popped into the retail section of Field + Fort where Bo was seen checking out the Flamingo Estates section which stocks books, candles, soaps and lotions.

They were later seen visiting nearby Mary Suding Antiques on Lillie Avenue.

A new pop-up clothing store at The Big Yellow House in Summerland caught their attention with its colorful display of goods near the parking lot.

Bo was seen checking out a bright pink floral silk robe on a clothing rack she later purchased.

Then it was on to the famous Summerland Antique Collective that has a large celebrity clientele and is a favorite of Oprah Winfrey.

An outdoor furniture set made of teak caught Bo's attention and she was seen leaning over to check out the price. 

The two friends spent over an hour before leaving and heading off towards Santa Barbara.

Bo shot to fame in the 1979 movie 10 opposite Dudley Moore, whose character becomes obsessed with her after seeing her at her wedding and follows her and her new husband to Mexico.

The movie's title refers to Moore's rating of Derek's looks on a scale of one to 10. 

And Bo has pretty much kept that rating as she got older, choosing to forgo plastic surgery and age naturally.

She told Closer magazine in 2018: 'There is a certain expectation [to look young]. 

'I get credit on one hand for not having a facelift, and then, on the other hand, it's "Oh my God, why doesn't she do something?"

'So you're just torn. I just have to keep busy, have other interests, and try not to think about it.'

She said she enjoys her life with Sex and The City actor Corbett on their 'Cliff Manor' ranch in Santa Ynez: 'We have a beautiful home with horses and dogs.'

Bo keeps her 5'3' frame fit not by going to the gym but by swimming and just doing work around the ranch, she says. 

'We don't have help,' she told Oprah Winfrey in 2011. 'I like the chores. I'd rather clean stalls than do exercises in front of a mirror!'

Bo was born Mary Cathleen Collins in Long Beach, California, and was stunning from the get-go, working as a child model.

She was renamed 'Bo' by her first husband, actor and director John Derek—thirty years her senior - whom she met at the age of 16, and married at 18 in 1976.

John Derek passed away at the age of 71 in 1998 from heart failure.

She met current spouse John Corbett in 2002 and they wed in 2020.
