"Riverdale" stars Lili Reinhart and Camila Mendes have reunited on The CW show's set.
The picture shows Reinhart, Mendes and Petsch wearing bathrobes as they cuddle up on a hammock. Reinhart said on Instagram Stories that they were shooting scenes in swimsuits in 60 degree weather.
"This is an ad for bathrobes," she captioned the group photo.
Mendes had shared a video on Instagram Stories that morning of herself driving to work with co-star Cole Sprouse.
Reinhart plays Betty Cooper on "Riverdale," with Mendes as Veronica Lodge, Petsch as Cheryl Blossom and Sprouse as Jughead Jones.
The series co-stars KJ Apa as Archie Andrews, and will premiere its third season Oct. 10.
"On some level, this next season will be about how our characters try to maintain their decency and optimism while living in the once all American town, which has now descended into chaos," he added.
