The new COVID safety rules on the “Riverdale” set definitely kill the mood during romantic scenes, but they have to be done.

KJ Apa shared a clip of himself and co-star Camila Mendes gargling mouthwash before filming an Archie and Veronica kissing scene.

The actor wrote, “Our new normal is washing our mouths before every take of a make-out scene…” with Mendes re-posting it alongside a champagne emoji on her Instagram Story.

The pair, who linked arms to down their mouthwash shots, struggled to hold it together as someone off-camera counted them down.

New episodes of “Riverdale” are expected to air in January 2021.
