Outspoken popstar Pink isn't fazed by other people's criticisms of her because no opinion is as hard as her own.

The GOD IS A DJ hitmaker still has days when she wakes up feeling useless, despite enjoying a string of successful hits and being newly married.

She says, "To a certain extent I am proud of myself for keeping hold of my integrity and taking risks and not completely conforming.

"On the other hand, I am my own worst enemy, my own worst critic, and I am extremely hard on myself.

"I have fat days, ugly days, depressed days, etc.

"I allow myself five minutes to rip myself apart, and then I give myself the rest of the day to put me back together."
