She is famously open about her struggles in her song lyrics and her hit So What saw her mark her break-up with Carey Hart. And while the married couple, who have a  daughter named Willow Sage, are now going strong once again, Pink has said her relationship still isn’t always smooth sailing.

The star has spoken out about the way in which she continues to draws on her tough experiences when it comes to writing music. She opened up to the latest issue of Billboard magazine, for which she also stars on the cover.

The 32-year-old said: ‘It’s funny. I wrote Family Portrait when I was 21 and my parents divorced when I was nine, so I tend to hold onto things. I’m still exorcising some of those demons.

‘And look, 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.”’

She humorously said she responds to her beau with the words: ‘“Yep. Thanks, baby, you’re my muse.”’

The cover of the August 25 issue of the music magazine sees the singer’s lean figure forming the letter ‘I’ in ‘Pink’. She can be seen sporting black lace leggings, matching court shoes and a matching jumper, over a white shirt with the collar turned up.

Pink also chatted to the publication about why she reckons she has had more success in the UK than the US. She explained: ‘I was always on the road in the UK and Australia, and things were really great over there.

Then I got to come home and be left alone. And you know what? It gave me lot of time to create my show and to become a performer.

‘I would go on 22-month tours and work my a** off, and it’s been the biggest blessing of my life that now I am a touring artist. It got me out of the popularity contest that music can be sometimes and gave me time to hone my craft as a stage performer.’

She added: ‘I’m also grateful, and I got to come back and do the Grammys [in 2010]. That was my “A-ha”.’
