In light of this, fans will allegedly see Sydney Sweeney's Cassie leading a double life, where she is an adult content creator in secret and reportedly has an OnlyF*ns page by the name of "Playboy Bunny."The show will also see Jacob Elordi and Zendaya returning in their roles as Nate and Rue, respectively. Nate, who is Cassie's fiancé in the series, catches "Playboy Bunny" in action while she is shooting for the channel in her room, and this leads to a rift in their relationship as well.The season is set to explore much more adult themes than before, and this considerably makes sense, since the last season concluded four years ago. In Season 3, Euphoria will move on from the high school themes that were previously explored on the show, now moving on to more mature themes, showing the various emotional, s*xual, and professional conflicts that the characters will face as adults as they navigate college life.Although the themes explored in the show this time will differ drastically from the previous ones, the show will still maintain the same flair of intensity, with drama, conflict, and tension spread across the season.Filming for Euphoria Season 3 concluded in October 2025 and is set to be available to stream sometime in 2026. Once released, the show will be available to stream on HBO Max.READ MORE: Euphoria Season 3: Everything we know so far about the next chapter of the HBO series
