Pink fights like a "pit bull" with her husband.
The 'Blow Me (One Last Kiss)' singer - who reconciled with Carey Hart in 2009 after a highly-publicised separation - has revealed their explosive fights could last up to six hours and made her feel "powerless", despite putting on a tough front.
Reminiscing about their stormy rows, Pink told Advocate magazine: 'It's usually that you feel vulnerable, that you feel powerless, that you feel out of control, that you feel scared.
"I'm a pit bull, but I'm a toothless pit bull. I will totally attack, but I just really wanted you to rub my tummy.
"Why when I bite you do you not understand that I just want you to rub my tummy?"
The couple now have 16-month-old Willow and the feisty singer can't wait to hit the road on tour with her daughter and her husband in tow because she is excited about becoming a real "gypsy family".
Pink laughed: "We're just going to be a gypsy family travelling the road.
"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."
The 33-year-old star also explained she comes from a humble background and her recession-hit family are determined to never let her forget her roots.
Pink - real name Alicia Moore - said: "I just know that half of my family is pissed off, and we're all working-class people. My mom is a nurse, and my dad was an insurance salesman, and my brother works for pennies for the military, and some of my family is unemployed.
"People are like, 'You live in a f*****g bubble, you live in Hollywood.' And I'm like, 'Yeah, I've got money now'."
