Greta Thunberg is known for commanding global attention with a single speech. Her younger sister, Beata Monalisa, is doing the same thing, just with a microphone, a stage, and a lot more glitter.

First making headlines with her 'Fridays for Future' movement, Greta Thunberg's name has become synonymous with climate activism and political urgency. On the other hand, Beata has taken a sharply different route, standing in the spotlight as a risqué pop performer who is as expressive as she is unpredictable.

Both sisters make their voices heard, just in starkly different ways.

Who Is Beata Monalisa?

Born Beata Ernman Thunberg, the 20-year-old Swedish singer has been curating her own identity in music, exploring drama, movement, and a strong sense of self. Performing under the name Beata Monalisa, she mixes jazz influences with modern pop theatrics, delivering vocals that feel far more seasoned than her years.

Beata Monalisa has been dancing since childhood and began singing at seven, eventually shaping a performance style that commands a room. Recently, her cover of 'La Vie En Rose', originally by Édith Piaf, has gained online traction. Belting out the classic tune in her signature style, Beata Monalisa's rendition has garnered a number of likes and praise on Instagram.

Anyone who follows the pop singer on social media would notice that she is unapologetically authentic. Much like her older sister, it appears to run in the Thunberg DNA to refuse to relent when something matters to them.

From lace bodysuits to hyper-feminine styling, Beata Monalisa's aesthetic revolves around fearlessly risqué exaggeration. It's been noted that the impact she makes through her daring style choices contrasts with the more reserved public image often associated with her sister.

Musically, Beata is working towards her debut album, a project she has been developing for years. Every track is self-written, with themes centred on identity, freedom, and empowerment.

Beata's artistic voice first came into focus with her 2024 debut track, 'I Found Your Father's Gun', a provocative, metaphor-driven release she wrote, produced, and performed herself. The song flips the language of objectification, turning it back on men who reduce women to body parts. Beneath its theatrical edge lies a razor-sharp message about power, double standards, and reclaiming agency, delivered with a fearlessness that defines her emerging persona.

Two Sisters, Different Impacts

If Greta's platform is about collective responsibility for the planet, Beata's is about personal expression.

Despite their contrasting directions, the sisters appear to share one key trait: conviction. Greta channels hers into activism and policy, going above and beyond to make a positive change for the world (In the words of Rob Newman: 'there is no planet B.'). Taking a road on the opposite side of the spectrum, Beata Monalisa channels conviction into performance and art, belting high notes and expertly dancing on poles.

The result is a rare dynamic where two public figures from the same family occupy entirely different cultural spaces. One stands in front of world leaders. The other stands under stage lights.

To that effect, comparisons are inevitable, as Beata Monalisa and Greta Thunberg are night and day. Nevertheless, both siblings are undeniably making an impact, each shining in their own ways.
