Martha Stewart is a knockout in sultry throwback photo: 'Wish it was taken last month!'

Well hello, Martha!

At 76 years old, Martha Stewart typically sticks to stylish pantsuits and a simple blowout. So we did a serious double-take when she posted a vintage snapshot of herself looking sexy as ever in the 1980s!

Rocking feathered locks, sky-high heels and a little black dress that showed off her cleavage, Martha is nothing short of a blonde bombshell.

"My assistant found this great photo of me in my library at Turkey Hill," Martha wrote on Instagram. "Wish it was taken last month!!!"

Although she's now known for her expert crafting, cleaning and catering, Martha did in fact work as a fashion model before becoming a businesswoman. She even, for a time, modeled in Paris. Check out some of the photos here -- and prepare to be pretty shocked!

After modeling steadily through the early 1960s, Martha would become a stockbroker and then make the life-changing decision to start a catering business out of her basement. And by the 1980s -- well, you know the rest.

Oh, and did we mention that, at the time, she was a young mom?! Truly a queen of doing it all!
