The premiere of Sam Levinson's new HBO series The Idol came with many surprises, including a brief cameo from Alexa Demie, who may or may not be reprising her role as Maddy Perez from Euphoria in The Idol. The Idol is a drama created by Euphoria's Sam Levinson and Abel "The Weeknd" Tesfaye. The show follows pop star Jocelyn as she returns to her singing career after a mental health crisis and enters a questionable relationship with a cult leader.
