Sia has been forced to clarify recent comments where she admitted she had to quit a songwriting session with Katy Perry after just an hour.
In an interview with Rolling Stone, she said: "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'."
Since the quotes came out, Sia has taken to Twitter to insist she wasn't accurately quoted.
Sia and Katy eventually did work out their differences, as the pair co-wrote 'Double Rainbow' which appeared on Katy's last album 'Prism'.
