Pink is "very open" with her sexuality.

The singer has been married to husband Carey Hart since 2006 and the couple share 16-month-old daughter Willow together.

Although Pink is currently enjoying a loving heterosexual marriage, the star doesn't feel like her sexual orientation is set in stone.

"Honestly, I've never defined myself. I've never felt the need to. I still don't," she told the November issue of The Advocate.

"The kind of world I live in and lived in was this sort of very open one. I was like a club kid. I was a little candy raver, and I am the kind of person that sucks the marrow out of the bones of life. Those days were really crazy and lots of all-nighters."

Pink accepts her hectic life as a performer.

She imagines that her brood will be extremely cosmopolitan in the future.

"We're just going to be a gypsy family travelling the road," she laughed.

"The best thing is that all my band and most of my dancers and everybody, we've all been together for so long that I look at them now as my future babysitters."
