Pink has hailed her less-than-perfect marriage to motocross racer Carey Hart for providing her with inspiration for her songwriting.
The So What hitmaker wed Hart in 2006, and, following a brief separation in 2008, they welcomed their first child together, daughter Willow Sage, in 2011.
But Pink admits she often loses her temper with her husband and she finds it easy to pour her emotions into lyrics for her tracks.
She tells Billboard magazine, "I'm in a relationship that I've been in for 10 years and it's never going to be perfect. Carey always jokes, 'You're always just mad enough at me to write a song' (and I reply) 'Yep. Thanks, baby, you're my muse.'"
