Meryl Streep and Cher turn back time mirroring outfits from ‘Silkwood’ premiere 40 years ago

We can’t “Believe” how amazing they look.

Meryl Streep and her best friend Cher dazzled Monday night at the iHeart Radio Music Awards in outfits reminiscent of those the pair wore to the premiere of their film “Silkwood” in 1983.

Photos obtained by The Post show Streep, 74, in a white Lanvin dress while the “The Shoop Shoop Song” hitmaker, 77, dons a chrome-encrusted black top with matching pants.

The duo’s outfits greatly recall — if only by accident — the ones worn by the pair during the film’s Los Angeles premiere.

“Silkwood,” which was nominated for five Academy Awards, tells the story of Karen Silkwood (Streep), a nuclear facility worker, who becomes a union activist after she becomes concerned with the plants safety practices.

Streep is joined in the film by Kurt Russell, Cher and Craig T. Nelson.

The “Sophie’s Choice” star appeared mid-show at the Dolby Theater in LA to introduce her longtime friend and recipient of this year’s Icon award.

“Back in 1965, I was a 14-year-old freshman in high school in Burnsville, New Jersey,” Streep began to a screaming crowd. “I walked two miles to school every day and back then we didn’t have earbuds or phones or earphones or Walkman or anything. We just had the songs that we carried in our heads and our footsteps made the beats that we walked to.”

“And the song that I carried in my head in 1965 was the number one hit,” the actress continued. “And it was [‘I Got You Babe’].”

Streep joked that at the time she thought Cher, who was 17 when the hit was released, was “really old.”

“She could have been a senior,” the “Devil Wears Prada” actress stated. “And now we both are seniors.”

“Zoom ahead to this past Christmas okay, that girl Cher has another number one hit,” continued Streep, referring to the hitmaker “DJ Play a Christmas Song.”

“She’s 77 years old and that doesn’t actually feel that old to me now,” Streep — who worked with Cher on the 2018 hit film “Mamma Mia! Here We Go Again” — laughed before stating the songstress is the “only woman in US history” to have a No. 1 hit “in every one of the last seven decades.”

The “Mamma Mia!” star believed Cher’s success came from her “giant heart” and how “she leads with her heart.”

“When I first met her 40 years ago, when we made a film about an activist called ‘Silkwood,’ said Streep to tumultuous applause. “And in the movie we we held on to each other and we rocked on his porch swing on a little house in Sherman, Texas on an October night.”

“And I sang her a lullaby but all I could think of is we are going back and forth was ‘I Got You Babe,” Streep reminisced.

After a montage featuring all of the singer’s achievements, Cher herself took the stage alongside EGOT winner Jennifer Hudson for a rousing performance of her two greatest hits: “If I Could Turn Back Time” and “Believe.”

“Meryl, Jennifer I want to thank you,” the icon began after taking the trophy from Streep and cracking a joke about how she has worn the same pair of pants for over 40 years.

“I feel so lucky to have people who have stayed with me for all these years,” Cher continued, adding that she had been “down and out so many times.”

“I never gave up my dream,” she continued. “I love standing on this stage and this is kinda my dream and I stand there and the music play and all of a sudden, out of my body comes this voice and people seem to like it.”

“So, what I want to tell you from my experience is have a dream and don’t give it up no matter what happens,” she concluded. “Because I know, from my own experiences, if you have a dream and you stick with it you will have a wonderful life and it will come true.”
