Sia, born Sia Kate Isobelle Furler on this day in 1975, has been a part of the music world since the mid-1990s. A veteran in the industry, Sia has written for and collaborated with some of the greats — Beyoncé, Rihanna, Britney Spears, Katy Perry, Shakira, and Christina Aguilera, to name a few.

She’s also known for her signature face-obscuring wig.

Sia discussed the purpose of the wig, explaining to Kristen Wiig in an interview with Interview magazine:

Her wig has become iconic, and in many of Sia’s music videos, dancer Maddie Ziegler dons similar wigs to emanate the Sia style.

Her album, This Is Acting (2015), was actually created with hits (which she wrote) that were never picked up by A-list artists like Adele and Beyoncé.

Sia told Rolling Stone:

Turns out, she was right. The single “Cheap Thrills” reached the top spot on the US Billboard Hot 100. Her music videos for many of the songs from the album have amassed billions of views, and her YouTube channel has more than 9 million subscribers. It’s safe to say those songs were hits, indeed.

So happy birthday, Sia! You’re one of the baddest in the game. TTYL, we’re going to go celebrate you by listening to your Christmas album.
