Billie Eilish at East Highland High? You better be joking. In her Time Capsule interview series with Vanity Fair, the seven-time Grammy winner was asked about the biggest rumour currently swirling about her. And she said, "Oh, that I'm in the third season of Euphoria." Quickly followed up with, "That's not true." However, not all hope is lost – as Billie said she'd be open to the idea. "I'd like to be!" she exclaimed. "Euphoria is fire." While the idea of Billie stepping into the world of Jules (Hunter Schafer), Cassie (Sydney Sweeney) and Lexi (Maude Apatow) might seem a little far-fetched, it might not be that crazy. As it wouldn't be the first time the singer has collaborated with the HBO drama. In January 2021, Billie and Rosalía teamed up for the song Lo Vas a Olvidar, which was featured on the soundtrack for the first season of the teen drama. As for the casting rumours, most of them seem to have originated from a fake Twitter account. The third season of Euphoria is expected to premiere on HBO in late 2023.
