Madelaine Petsch Has a Riverdale Reunion with Lili Reinhart and Camila Mendes at Strangers Premiere: 'My Girls'

Madelaine Petsch is still very much in touch with her Riverdale costars!

Petsh, 29, was joined by Camila Mendes and Lili Reinhart at the Los Angeles premiere of The Strangers: Chapter 1 on Wednesday, May 8.

The upcoming horror flick, hitting theaters Friday, May 17, stars Petsh and Froy Gutierrez as a couple whose anniversary vacation goes haywire when their car breaks down in a sketchy small town. The first film in the franchise premiered in 2008, with it being followed by 2018's The Strangers: Prey at Night.

The movie star gushed about having her former costars support her next endeavor in a sweet Instagram post that showed the trio smiling from ear to ear on the red carpet and sharing a hug.

"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 🥹."

The photos showed Petsh wearing a sexy, low-cut black Diesel dress. Mendes, 29, opted for a nude Altuzarra midi dress, while Reinhart, 27, wore an elegant black gown.

Mendes and Reinhart continued their support in the comment section writing "love you guys 🥹," and "❤️my loves ❤️."

Another one of their former costars, Marisol Nichols, also left a sweet comment that read, "I think one of my greatest pleasures on set was watching you all bond and grow up together. Congrats Mads ❤️❤️❤️."

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."
