Pink is worried about her children's future.

The 'What About Us' hitmaker - who has six-year-old daughter Willow and nine-month-old son Jameson with her husband Carey Hart - admits she is scared for her kids and says it will ''break her heart'' when her eldest child finds out the ''kind of world she lives in''.

She said: ''I have a 6-year-old little girl who I'm raising, and the day she figures out what kind of world she lives in is going to be the day that breaks my heart. I don't yet know how to have that conversation. I'm hoping somebody else makes a speech and teaches me before that day comes. And that's what 'What About Us' is to me.''

And Pink - whose real name is Alecia Moore - also revealed it is her husband Carey that inspires some of her music too.

She added to the HuffPost: ''I'm a 38-year-old woman that's a mother of two children. I've been married for 11 years. Either on or off. Mostly on. My parents are ageing. My dad just beat cancer. I'm putting one foot in front of the other just like everyone else. I just have a pen in my hand. And a lot of people get to hear about it. But it's the same s**t everyone is going through.

''He pisses me off. He's my guy. He's my person. From one minute to the next, I look at him and am like, 'You're the best man. You're the best dad. You're beautiful and I love you.' And then five minutes later, it's like, 'There's nothing I've ever liked about you.' And I know he feels the same way about me.''
