The 22-year-old actress and musician was joined by her co-star Joe Keery for filming on season four.
Later that day, Gaten and Sadie were spotted riding their bikes around town at sunset while filming additional scenes.
Their co-star Natalia Dyer recently opened up about the upcoming fourth season.
“Honestly, the scripts are great. I’m very excited. I’m excited for Nancy. Every time we end a season, we all think, where is this going to go? Where can this possibly go?” she told Vogue India.
“Then we get the scripts for the next season and we’re, like, ‘Oh my god, wow, like, wow!’ So, while I can’t say a lot, except that it’s going to be a while before it comes out, it will definitely be worth it. It’s going to be really big. It’s going to be big!” she added.
