Millie Bobby Brown jokes about ‘Ozempic Vecna’ and ‘Stranger Things’ fan theories on ‘The Tonight Show’

The episode also featured games, giveaways and a surprise video message for Brown

Millie Bobby Brown appeared as co-host on The Tonight Show Starring Jimmy Fallon and opened the episode by discussing her long history with the programme and her evolving public persona.

She reflected on growing up in the spotlight, noting past criticism about interrupting co-stars and joking, “I’m just excited,” while Jimmy Fallon reassured her throughout the exchange.

Their conversation shifted to the arrival of Season 5 of Stranger Things, which is currently streaming in two volumes and remains one of Netflix’s most successful global releases.

Brown addressed a popular online joke about Vecna looking slimmer this season after fans suggested “he’s on Ozempic.” She acknowledged the comments with amusement, saying it was unexpected to see so much attention on the villain’s appearance and adding, “God help him if he gets a little lip filler.”

She also confirmed that Netflix regularly pitches spin-off ideas, sharing examples that have circulated internally, including “Is Dustin Cake?”, “K-Pop: Demogorgon Hunters”, “With Love, Vecna”, and the one she “almost said yes to,” titled “Eleven in Paris.”

During the broadcast, Brown spoke about her affection for the 1980s setting of the series, her recent marriage into the Bongiovi family, and her admiration for Taylor Swift, linking Swift’s eras to her own journey as Eleven.

The episode featured games, the giveaway of a Christmas sweater to an audience member, and a surprise video message from the cast of The Secret Lives of Mormon Wives, which left her visibly delighted.

As Stranger Things approaches its final episode, Brown said she remains “forevermore in debt to the Duffers and Netflix,” expressing both gratitude and sadness as she prepares to say goodbye to the role that shaped her career.
