Jaclyn Smith, 77, was the FIRST star to model Daisy Duke denim shorts

Jaclyn Smith, 77, shared a beautiful photo on Instagram on Wednesday.

The beauty uploaded a flashback photo from her modeling days in the early 1970s.

The image proved that she was the first star to model Daisy Duke shorts as she wore the blue denim cut-offs in her image.

The Texas native paired the shorts with a white top that showed off her toned tummy — it also looked like something Hailey Bieber would wear today.

It’s unknown what the ad was for, but before she became a TV star, she was the Breck shampoo girl.

The American actress is best known for her role as Kelly Garrett in the television series Charlie’s Angels that aired from 1976 to 1981.
