Everything To Know About Sia’s Life

She may have one of the shortest names in showbiz, but in reality, Sia’s full name is much longer. Born Sia Kate Isobelle Furler, it’s safe to say she made a smart call trimming it down. I mean, can you imagine that name stretched across an album cover? Yeah… keeping it short and sweet was definitely the right move for the Chandelier singer!

In the mid-90s, Sia began her career as a singer in the local Adelaide acid jazz band, Crisp. In 1997, when Crisp separated, Sia released her debut studio album, OnlySee in Australia, which only sold 1,200 copies. The aspiring singer later moved to London and joined the British duo Zero 7. She eventually left the band and went on to release her own solo albums before officially going mainstream with Titanium, Wild Ones, and later, Elastic Heart.
5. She Starred in ‘Home and Away’
She’s Australian to a T! Sia starred as a wedding singer on a 1997 episode of TV soap, Home and Away. In an attempt to make a name for herself during the release of her debut album, Sia made a cameo on the Australian drama. Sadly, the cameo wasn’t enough for Sia to shoot to fame. It took another four years for the star to finally release her first major album, Healing Is Difficult (in 2001).

Other than being a vocal prowess, Sia is also a skilled songwriter. In the early 2010s, Sia retired as a singer and focused on her career as a songwriter.

It’s my favorite part of the job, writing.”
In fact, Sia has written the lyrics to many critically-acclaimed tracks including Pretty Hurts by Beyoncé, Perfume by Britney Spears, Sexercise by Kylie Minogue, Let Me Love You by Ne-Yo, and Diamonds by Rihanna. Bonus fact? Sia allegedly wrote Diamonds in just 14 minutes!

9. What is Sia’s Sexuality?
Sia has always been open about her sexuality. In 2009, the singer told Same Same [via Elle]: “Before I was actually successful I’d always said I’ve always dated boys and girls and anything in between. I don’t care what gender you are, it’s about people.”
In 2013, Sia specified that she is bisexual, telling Twitter [via Economic Times], “I’m queer. I don’t identify as a lesbian because I’ve dated men predominantly. But I’ve certainly dated women.”

Talking to The Sunday Times, Sia said that it took “six years” to come to terms with his death: “I was pretty fu**ed up after Dan died. I couldn’t really feel anything. I could intellectualize a lot of stuff; that I had a purpose, that I was loved, but I couldn’t actually feel anything.”
12. Did Sia Have a Drug Addiction?
Following the death of her boyfriend, Sia admitted that would self-destruct. Talking on Grounded with Louis Theroux, Sia revealed that she battled a drug and alcohol addiction. Discussing her reliance on Vicodin and Oxycodone, Sia disclosed: “We were all children, 19-20 years old. We all became very reliant on drugs and alcohol, to sort of soften the blow of his loss.

I have seen the [former] Canadian minister of defense discuss the fact that he knows that the American government is working with five different species of aliens presently. Which is a real fu**ing mind-blower. I want to believe in a way that makes me feel a little bit scared. So then I like to think about dogs because it makes me feel safe. And mermaids. I believe in Daryl Hannah.”

In 2015, she also contributed to the song Free the Animal for a PETA PSA encouraging people to stop using animals for their skin.

Discussing her boys transition out of foster care, Sia told The Project in 2021, “There has been a lot of heartache. There has been a lot of lost trust and then a lot of regained trust,” she added. “But I do trust them both. And I’m proud because they’ve come a very long way.”
18. Does Sia Have a Medical Condition?
