“Wonder Woman” star, Lynda Carter, shocked fans with her age-defying appearance on social media.

The 75-year-old actress stunned in a series of photos shared on Instagram on Tuesday, July 28, while promoting her latest project, “Super Troopers 3.”

“@supertroopers Ride Again!!! Follow them and us (returning cast) For a fantastic road romp!!” she captioned the post. “But….wait for it…the last scene! I’m naked in a bathtub???? Oh noooo, @jaychandreskhar you promised not to show that!”

In one of the photos, Carter is all smiles as she lies outside in a bathtub, with bubbles covering her chest and an elegant updo. Behind Carter is a picturesque view of a lake and greenery, and a martini is seen on a table next to her.

When speaking to People in March 2024, Carter shared her secret to looking youthful in her 70s, telling the outlet, “People still recognize me all the time as Wonder Woman,” adding that since she hasn’t “cut” her face, “I probably look just myself, but older.”

“And the reason I’ve never had any facial surgery is just because I’m afraid. It’s scary, because we’ve all seen some bad ones,” she said. “That outcome is spending time in a chair with some really good people doing your hair and makeup.”

She explained that while most “actors and celebrities always look so great when they’re on the red carpet,” they often look like everyday people without makeup on and when wearing regular clothes.

“If everyone did a three-hour makeover before they left the house, then they’d all look amazing,” she said. “What I’m trying to say is, there’s a lot of effort behind those pictures. Don’t think they walk out the door looking like that!”

Carter rose to stardom with her career-defining role playing Wonder Woman in the eponymous show, from 1975 to 1979. Decades after the show went off the air, fans continue to associate Carter with the iconic character, but she says she doesn’t mind.

When speaking with E! News in October 2016, Carter explained that speaking about the show has never been an issue for her.

“I love the character. I love her. I think she stands for so much…I’ve heard so many great stories,” Carter said. “She became so much more than this show or the comic book or the movie, she became a symbol for the beauty and the strength and the loving kindness and the wisdom of women…and gay men.”
