Jaclyn Smith is how old?!

The “Charlie’s Angels” actress, 78, shared an excellent snapshot of herself and her 41-year-old son, Gaston Richmond, on Instagram earlier this week.

“Shine, My Boy!” Smith captioned the adorable photo, but the actress-turned-businesswoman’s youthful appearance swiftly dominated the conversation.

“He looks more like your brother than your son,” one fan remarked, while another added, “God gave you some good genes, Jacqueline.”

Smith also uploaded a photo montage commemorating her son’s birthday in March.

“He safely came on this globe, making me the happiest lady on the planet,” she added. “It appears that he began surfing before walking… Constantly inquisitive, acutely perceptive, and endowed with the kindest, most sympathetic heart. He is still one of my favorite people on the earth.

“Gaston, you will always be my shining son. Congratulations on your 39th birthday! “I adore you.”

Richmond has followed in his parent’s footsteps and now works as a camera operator. His IMDB credits include the 2020 revival of “Party of Five,” as well as “Shameless” and “Fresh Off the Boat.”

Smith also has a 36-year-old daughter with her ex-husband, filmmaker Tony Richmond. The couple married in 1981 and divorced in 1989. Since 1997, she has been married to cardiothoracic surgeon Brad Allen.

The brunette beauty is also clearly devoted to her two grandchildren, Oliva Rose, 2, and Spencer’s 5-year-old daughter Bea. Her Instagram feed is filled with pictures of her grandchildren.

Smith’s social media accounts also reveal how she keeps her youthful appearance: gardening, yoga, and sipping green smoothies.

She tweeted a recipe for a spinach and cucumber-infused drink in February, which she described as “amazing and gives me a surge of energy!”
