Wonder Woman star Lynda Carter, 72, stuns in a plunging swimsuit in image from 50 years ago as she promotes her new song Pink Slip Lollipop

Lynda Carter shared a stunning throwback photo to Instagram on Monday.

The original Wonder Woman star, 72 — who recently joined forces with Moms Demand Action to end gun violence — looked incredible when in her 20s.

She had on a low-cut silver swimsuit as she put her hands on her hips like a superhero. The star had her long hair down with the front pulled back. Her makeup was light, showing off her natural beauty.

The image is being used for her new song called Pink Slip Lollipop.

The TV icon unveiled a snippet of the fun track, showcasing a twangy pop beat, electric guitar riffs, and exuberant background vocals. 

She also revealed the cover art for the ditty, featuring a stunning throwback photo of the former pageant queen, bathed in a pink hue.

'Boys, get ready for the pink slip. This one’s for the ladies!' Lynda captioned the post. 'PINK SLIP LOLLIPOP A hot new pop single, streaming June 21 on @applemusic, @spotify, or wherever you listen to music.'

The announcement comes after the beauty honored her late husband Robert Altman with an emotional song released on Valentine's Day called Letters From Earth. 

'The soul of the song is about how you miss a person so much, because they're such a presence in your life that it's almost impossible to imagine that you won't physically see them again in this life,' she told People in February. 

'You wonder, "How can I communicate with you? Where are you? You didn't just die — there's too much of you left on this earth, too many people that love you."'

The heartfelt number includes lyrics like 'Letters from Earth, sealed within my heart, delivered in my dreams, ever since we’ve been apart …' as well as 'Do you know that spring came early? Have you heard the world’s at war? That I moved down to Miami, and I love you more and more?' 

The song is a tribute to video game executive Altman, to whom she was married from 1984 until his passing from a rare form of leukemia in 2021.

Together, they shared a son, James, 35, and a daughter, Jessica, 33

Lynda also noted that people are often surprised to learn she is a singer, despite the fact that she was performing long before she became famous as the lead in Wonder Woman when the show premiered in 1976. 

'I've been singing for over 50 years,' she told the outlet. 'I started singing in clubs when I was 14, and was writing music before I became an actor.'

Since Altman's passing, Carter has collaborated with City of Hope to help fund critical research for complex blood cancers like the one that claimed her husband.

Altman was initially diagnosed with myelofibrosis, a disorder affecting bone marrow cells, which later progressed to secondary myeloid leukemia, a condition with limited treatment options.

In another charitable venture, Lynda recently joined forces with Moms Demand Action in their mission to end gun violence.

In a heartfelt statement, Lynda said, 'As a mother myself, I want what all mothers want: for our kids to come home safe and for our families to not be devastated by gun violence.

'Guns should never be the leading cause of death for our children and young adults,' Carter continued.

'Securely storing firearms and advocating for common-sense gun legislation can save lives and prevent tragedies.'

With a robust network of dedicated volunteers in every state, Moms Demand Action empowers individuals to advocate for gun safety policies and initiate local efforts for a safer future. 

Partnering with this organization, Lynda seeks to elevate the voices of mothers nationwide and effect substantial change.

'Last year, Carter released her empowering single Rise Up, a rallying cry for unity, action and change,' a press release said.

'Now, she's harnessing its message to mobilize mothers everywhere in the battle against gun violence. Carter's dedication to inciting positive change aligns with her broader goal of mobilizing communities before the crucial 2024 election.'

Meanwhile, her daughter Jessica Carter Altman is also a singer. She has just released the song Clumsy (Wedding version) and will be performing at the Troubadour in West Hollywood on June 17.

'I’ve always been a clumsy person. I trip over invisible cracks in the sidewalk and *almost* knock everything over all the time. Somehow these little stumbles and clumsy moments became a part of my love story. And I wouldn’t have it any other way,' wrote Jessica on Instagram this week.
