The actresses — who are co-stars in the hit film — kissed on the red carpet before posing with other members of the cast, Christina Baranski, Judy Cramer, Jessica Keenan Wynn, Alexa Davies, Amanda Seyfried, and Lily James.
Funny enough in the film, Cher, 72, plays the mother of Meryl Streep, 69, even though they're only three years apart. "That doesn’t make any difference," Cher confessed to People of their age gap in a new interview. "I was thrilled to death, and it was so silly. It was great fun, and I love her, so it was perfect."
The music mogul continued, "It was great, and she was hiding watching me sing, and I was so excited. I didn’t find out until afterwards — I would have been more nervous."
The last time Cher and Meryl appeared in a movie together it was in 1983's Silkwood. This time around for the Mamma Mia sequel, the two got to spend time together whilr they shot the "Super Trouper" scene.
"Meryl had just had [her daughter] Mamie, and we were downtown at her apartment, and she said, 'I want some ice cream' and I said, 'OK.' I said, 'Isn’t it dangerous down here?' And [Meryl] said, 'No no, it’s Little Italy on one side and Chinatown on the other side and we’ll be safe as two peas in a pod,'" she recalled.
"So we walk out and the first thing we see is some guy hitting cars with a brick. And then we walk down the street and we hear screaming. And we come around the corner, and this gigantic man is ripping the clothes off of this girl," Cher continued, adding that she and Meryl both started screaming and the man ran towards them.
"And just out of — I don’t know — we split and he ran through us. And we went up to the girl, and all of her clothes were torn and she was clutching her bag. So we’re putting her together, kind of trying to get her to look a little bit like she hasn’t just been ravaged, and she looks at us, and she goes, 'Oh my God! I was saved by Meryl Streep and Cher! I’m an actress, and I work in a café where we sing, and all my friends are going to be so jealous,'" she concluded. We can't wait to see the power couple in theaters on Friday, July 20!
