Who Is Beata Thunberg?
Beata is best known to most people through her sister. But she is much more than a renowned sister.
Since a very young age, Beata has been drawn towards the performing arts, a love that made her appear in a Swedish primetime television show, Bingolotto, at the tender age of 13. In the same year, she found her breakout role in theatres. She has been dancing and singing all her life, and she has made it very clear that she does not want to be remembered by her last name, but by her talent.
Bea has decided to shed the famous last name and use her mother’s maiden name instead. In her art life today she is Bea Ernman or Beata Ernman, a conscious and striking proclamation of autonomy.
Childhood and Family History
Beata was brought up in one of the most well-known families in Sweden. Both art and activism influenced her home from a very young age.
Her mother, Malena Ernman, is a renowned Swedish mezzo-soprano. Malena represented Sweden in the Eurovision Song Contest 2009 with the song La Voix, and she is also a member of the Royal Swedish Academy of Music, an icon of the Swedish cultural world.
Her father, Svante Thunberg, is an actor, film producer, and screenwriter. So Beata was brought up in an atmosphere of performance and imagination, exposed to life in front of people even before Greta became world-renowned.
Her mother called Bea the heroine of the family. “There is a heroine or a hero in every family. Beata is the protagonist,” wrote Malena in her 2018 memoir Scenes from the Heart, which was written before Greta Thunberg became a household name around the globe.
Career: Beata Thunberg as Singer, Actress, and More
The Forever Piaf Breakthrough
Her breakthrough came in the musical Forever Piaf, in which she played the role of young Edith Piaf between 2020 and 2022 at Göta Lejon in Stockholm. Sharing the stage with her mother, who acted as the elder Piaf, Beata received genuine critical praise for her strong voice and commanding presence.
“I have been dancing and singing since time immemorial. It is a dream to be able to perform the immortal music of Édith Piaf,” she said.
It was not a modest production. Göta Lejon is one of the most prestigious theatres in Stockholm, and landing this role at the age of 14–15 was no small achievement.
Music: “Bara Du Vill” on Spotify
She also stepped into the music industry, releasing her debut single Bara Du Vill as a teenager. Her Swedish-language pop song, which translates roughly to Only If You Want, introduced her as a solo artist with a genuine pop sensibility.
When the song was released on Spotify, her elder sister Greta gave her a public shout out: “So proud of my super talented sister, Beata Ernman. Hear her new song on Spotify.” That post revealed the supportive relationship between the sisters to the world, despite their very different public careers.
Advocacy Work and Television
Beata has done more than music and theater. She has been featured on Swedish TV and has consulted on programs addressing ADHD, OCD, and teen bullying. This shows her willingness to use her platform for real-life matters, not necessarily in the same way as Greta.
She has also been involved in the “Handbook for Superheroes” campaign, a book translated into 17 languages, giving her a meaningful connection to youth empowerment.
Why Beata Changed Her Name
This is the question everybody wants answered, and the story behind it is very human and understandable.
She has had to deal with relentless bullying and harassment connected to her sister’s activism. Greta even admitted in 2019 that her sister is the one who suffers most. Greta wrote in Swedish newspaper Dagens Nyheter: “She has been the victim of systematic bullying, threats and harassment. Those who threaten me and hate me do it to the entire family, even to her.”
So changing her name was not merely a branding decision. It was an act of self-defense and self-identification. By performing as Bea Ernman, she stepped out of the crossfire and into her own artistic world.
Taking her mother’s surname, Ernman, Bea has worked in recent years to build a career as a model, actor, and singer on her own terms, with an online presence that is clearly hers, bold, artistic, and unapologetically confident.
Beata Thunberg vs. Greta Thunberg: Two Sisters, Two Paths
People often compare the two sisters. Here is a clear breakdown:
| Aspect | Beata (Bea Ernman) | Greta Thunberg |
| Public Identity | Singer, actress, model | Climate activist |
| Known For | Forever Piaf, “Bara Du Vill” | Fridays for Future, UN speech |
| Approach | Artistic, performative | Political, activist |
| Social Media Style | Bold performance clips, fashion | Climate statements |
| Name Used | Bea Ernman / Beata Ernman | Greta Thunberg |
| Neurodiversity | ADHD, OCD (publicly discussed) | Asperger’s (self-disclosed) |
Both sisters are neurodiverse. Both are bold. Both are driven. They simply found completely different stages to stand on.
Personality and Image of Beata in 2026
A glance at her Instagram page or her performances makes it clear that she is comfortable engaging with bold topics around sexuality and politics, through provocative dance and a daring wardrobe.
She is on Instagram at @beatamonalisa. Her content is creative, occasionally dramatic, and never anything less than uniquely hers. No protest videos, no activist history. Instead, you will find performance clips, artistic aesthetics, and the energy of a young woman who has a very clear idea of what she wants her brand to be.
Six years after Greta admitted that her sister bore the brunt of the backlash, Bea is already following in the footsteps of her opera singer mother Malena Ernman, with an international music career in her sights. It is a full-circle story, and quite a compelling one.

Beata Thunberg’s Net Worth in 2026
Beata is still early in her career, though she already has real professional experience in theater, music, TV, and brand campaigns.
- Estimated net worth: Around $2 million (from various sources, not officially confirmed)
- Sources of income: Theater performances, music releases, brand work, modeling, TV appearances
- Financial support: Still partially dependent on family support due to her age
These are estimates and should be treated as such. Her career is growing, and her earning potential in 2026 will continue to rise.
What Makes Beata’s Story Stand Out Among Celebrity Siblings?
Most celebrity siblings either fade into obscurity or try to ride the fame of their well-known relatives. Beata did neither.
She entered a genuinely demanding artistic arena, because classical musical theater is not easy. She released original music in her own language. She changed her name on her own terms. And she insisted on keeping her identity her own, while still building a very real public artistic presence.
That balance is genuinely hard to find. It takes self-awareness and boldness to define yourself when the world already thinks it knows who you are.
Final Thoughts
Beata Thunberg, or Bea Ernman as she prefers to be called, is not a footnote in her sister’s story. She is writing her own. By 2026, at just 20 years old, she has performed at one of Stockholm’s most prestigious theaters, recorded music on Spotify, appeared on national television, and built a genuine social media following entirely on her own creative terms.
Her family was shaped by two things, performance and purpose. She chose performance, and she is pursuing it seriously and in her own way. Whether you know her as Beata Thunberg, Bea Ernman, or simply the girl with the big voice and the red lace outfits, one thing is clear: she is not going anywhere. She is just getting started.
