The Vogue Cover Interview That Reveals Her New Chapter

In November 2025, British Vogue featured Millie Bobby Brown on its December cover, marking a significant moment as the actress navigates life beyond her iconic Eleven character from Stranger Things. The in-depth interview shows a mature young woman reflecting on childhood stardom, personal growth, and unprecedented life changes. Brown discussed wrapping the beloved Netflix series after a decade of filming, describing the experience as “like a death of someone you love.”

The 21-year-old actress spoke candidly about her marriage to Jake Bongiovi and their decision to start their family through adoption. She emphasized that she and her husband share parenting duties equally, stating “we are 50-50 on everything.” Brown also revealed her passion for supporting animal rescue efforts, maintaining her animal shelter called Joey’s Friends and regularly rescuing dogs with her husband on their Atlanta farm.

From Child Star to Married Mother at 21

Millie Bobby Brown began her Stranger Things journey at just 10 years old in 2016, propelling her to international recognition as Eleven. By 2021, she met her future husband Jake Bongiovi through a mutual friend, and after three years of dating, they married in May 2024 when she was only 20 years old. The couple held a second ceremony in Tuscany, Italy in September 2024, with Matthew Modine from Stranger Things officiating.

The young couple’s next major milestone came quickly when Brown and Bongiovi announced they had adopted a baby girl in August 2025. In her Vogue interview, Brown shared her joy about motherhood, saying “It’s been a beautiful, amazing journey – she’s taught us so much already.” She emphasized protecting their daughter’s privacy, stating she will not disclose the child’s name until “she’s ready to decide for herself.”

Building an Empire Beyond Acting

Career Achievement Details
Net Worth (2025) $20 million
Production Company PCMA (founded by Brown)
Beauty Brand Florence By Mills (includes beauty, fragrance, clothing, eyewear, pet apparel, coffee)
Humanitarian Work UNICEF Goodwill Ambassador (appointed at age 14)

At 21, Brown has built a business empire that extends far beyond her acting career. Her Florence By Mills beauty brand launched a wide range of products available at Specsavers, Nordstrom, Boots, and Ulta Beauty. She established her production company PCMA to handle her film projects and is actively pursuing a veterinary technician degree in her spare time. Her $20 million net worth makes her one of the wealthiest young celebrities in entertainment.

Facing Online Criticism and Standing Her Ground

Despite her achievements, Brown has faced relentless online criticism since childhood. She called out publications for body-shaming and appearance-focused tabloid coverage, particularly during The Electric State press tour in fall 2025. When media outlets published headlines like “Why are Gen Zers like Millie Bobby Brown ageing so badly?” the young actress recorded a powerful response video that garnered 7.5 million likes.

“I am 21. I am going to have fun and play and be myself. Get off my fucking case, you know?”

What Lies Ahead for the Stranger Things Star?

As Stranger Things Season 5 concludes the beloved series in late 2025, Brown is positioned at a major career crossroads. She’s already committed to Enola Holmes 3 and other film projects through her production company. In her Vogue interview, she hinted at a mysterious project launching in 2026, saying “I have something in the pipeline that I’m really excited about, which I’ve never done before.”

The Stranger Things cast gathered emotionally when reading the final script, with Brown, Finn Wolfhard, Noah Schnapp, Gaten Matarazzo, Sadie Sink, and Caleb McLaughlin embracing in tears. Brown reflected on the experience: “We were all each other knew. We just all huddled and cried for five minutes straight.” Despite wrapping an era-defining show, she remains grounded by her farm life in Atlanta, her marriage, and her new role as a mother, embodying the kind of balanced success rarely seen in young entertainment professionals.
