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'.''
