Greta Thunberg gets her kicks out of campaigning against climate change, but music is more her younger sister's speed.

The Swedish activist, 23, has a sibling who is a star in her own right - but these two are in very different lanes.

Greta enjoys fighting for social, environmental and human rights causes, lobbying governments and waking up the world to the reality of the climate crisis - whereas Beata MonaLisa prefers showbiz.

The 20-year-old pop star goes by 'Bea' and appears to be happy to let Greta run with their family name after adopting the mononym.

But interestingly, the singer didn't want to discuss her well-known relative when she sat down for a recent interview.

She brushed off potential queries about self-proclaimed 'climate justice activist' Greta by simply saying: "I’m not responsible for other peoples lives."

However, Bea did open up about herself and offered some insight into what it is like to be a budding musician from Stockholm trying to forge her own path while having a famous older sister.

She is a woman who wears many hats, as she describes herself as a singer, dancer, actress, model, producer, writer, songwriter and choreographer.

This array of talents makes a lot of sense, considering her mother Malena Ernman and dad Svante Thunberg are trained in opera, music and theatre. Both found success in these fields and are well known in Sweden.

Speaking to Insider, Bea shared some nuggets of knowledge about herself.

She's no stranger to being dragged into 'internet drama', she enjoys spending a lot of time at 'Scandinavia’s biggest gay club', while she is a huge fan of Beyonce and Michael Jackson.

Bea recently started gaining a lot more attention on social media when a video of her singing Whitney Houston’s hit ballad 'I Will Always Love You' went viral.

Discussing the reaction she received to her vocal talents, Greta's sister said: "There was a rumour in America that it was AI. At first, I was offended, but then I took it as a compliment. People were fully convinced.

"There was a lot of hate, as well. A producer actually called me and said, 'I saw how much hate you got, so I want to work with you'. It means you evoke emotions in people."

Bea explained she's been working on music since she was 13-years-old and records 'everything live', as she likes her songs to sound 'brutal and raw'.

Offering some more information on what childhood was like while growing up in the Thunberg family, she went on: "I started dancing when I was three and singing when I was seven.

"I performed in shows at school and everyone thought I was annoying. I was bullied by everyone. Now, the bullies follow me. They’re like, 'We went to school together'. I’m like…

"I went to a classical music school, but I didn’t enjoy it. I was in to pop music. I’m self-trained. I was cast as Edith Piaf and I played that role for five years, from 12 to 17. Imagine singing her songs every single day for five years."

The singer also confirmed that the name MonaLisa was in fact bestowed upon her at birth, as she explained: "It’s from my grandma Mona and great grandma Lisa."

Although Greta's life goal is to save the planet, her younger sister's current aspirations are to be 'accepted' and understood by people who listen to her music.

Speaking of what success looks like for her, Bea went on: "Maybe it’s a feeling. You can be worldwide famous and not feel accepted, or you can have a small fan base and feel very successful.

"It’s more important to have fans who understand you. They have the same interests, the same way of dressing, the same humour. I’m very sarcastic."

Bea said she is in the process of finishing an album that she has been working on for the last seven years, which will boast nine songs in total.

She wrote everything 'completely by herself', but says she has been tweaking it for so long as she is a 'perfectionist' - but she hopes to finally finish it off at some point this year.

The songstress then revealed one thing that she does have in common with her sister Greta - her disdain for US President Donald Trump.

Bea explained that she has a song that is set to be released which features lyrics 'where she makes fun' of the commander-in-chief, who once branded Greta a 'troublemaker' and suggested she 'has an anger management problem'.
