"Feeling so incredibly lucky to have my girls through every chapter of life. the strangers premieres only in theaters may 17th!!!!! 🩶🩶," Petsh wrote, while also adding in the comment section, "luckiest girl in the world 🥹."

Riverdale came to a conclusion after seven seasons on Aug. 23, 2023. In February, PEOPLE spoke to Mendes, who opened up about the continuation of her "lit" group chat with Petsch and Reinhart.

“No, it's not even like… It's not spicy. It's more just all of us like venting about things that are worrying us or being like, ‘Hey, are you guys also experiencing this?’ Like, we really lean on each other, especially coming out of this phase of our lives," she said. "We're all kind of experiencing the same anxieties at the same time and it's really nice to have people who relate to you and that way."
