In 2016, Reinhart got a cross inked on her right pinky finger (which she later called "impulsive" on Twitter, linking to a video of the process).
This is the one design you can spot on Riverdale. "We kind of gave up covering my [cross] finger tattoo. We literally don't cover it anymore. So if you look, you will see it. It's like an Easter egg," Reinhart told Refinery29 in 2017. She never gave a specific meaning behind it, but one can only guess it has to do with her faith.
