Sia reveals she quit within the first hour of working with Katy Perry

Sia may have written for everyone from Rihanna to Beyoncé to Adele, but there's one A-list pop star the camera-shy Aussie singer hasn't had the easiest working relationship with: Miss Katy Perry. Sia was speaking to Rolling Stone about her forthcoming studio album This is Acting - which features songs she originally wrote for other artists - when she revealed that she originally quit a writing session with the "dominant" Dark Horse singer because their working styles were polar opposites.

If a word or sentence sounds silly, then I'll change it, but I'm not analytical." She continued: "That's what was interesting about writing with Katy Perry because, again, it's her voice at the end of the day. She's also quite dominant, and she's extremely analytical. I actually quit within the first hour of our first session. "I was like, 'Can we both agree this doesn't work? Like our whole songwriting dynamic?' And she was like, 'I love it. It's like a puzzle to me. It's like a crossword.' And I was like, 'But this is boring for me. The analysis is totally boring for me. It feels like the enemy of creativity.' It was so cool to be able to have that conversation on why we wrote in such entirely different ways. I'm glad I didn't give up on it because I actually did get a song out of it, and we also really had a laugh because we were able to be authentic. The song that the pair did manage to get out of the session was 2013's 'Double Rainbow', which featured on Katy's last album Prism. Sia's new album This Is Acting, featuring lead single 'Alive', which was originally written for Adele is set for release on January 29. The record will serve as the follow-up to 2014’s 1000 Forms of Fear, which spawned hit singles 'Chandelier' and 'Elastic Heart'. Meanwhile, an evangelical Christian lady recently filmed a fraknly bonkers encounter with Katy Perry's pastor father, during which she called his daughter - among other things - a “a satanic women who’s led millions to hell”.
