Pink's daughter can't stop swearing.

The 'So What' songstress has admitted that her three-year-old daughter Willow Hart has a ''potty mouth''.

Talking to Ellen Degeneres on 'The Ellen DeGeneres Show' on Tuesday (14.10.14), Pink explained how she was left shocked when her daughter blurted out the f-word.

She said: ''She almost had a potty mouth. I was getting ready to go on stage and she ran in. She must have been preparing this, like a bit, and she came in and she was like, 'I'm f***ing here.'''

''She mutters it when she thinks no one is looking. But it's so cute. I mean, I'm not encouraging it, but come on! It's like this little three-year-old body and ... a precious little sailor.''

Pink also joked that her little girl shares many traits with her former motorcycle racer daddy, Carey Hart.

She told Ellen: ''[Willow]'s wild - she gets that from papa. I'm physically cautious. I'm physical, but I'm cautious. He's reckless and she's reckless.''

Pink has previously told PEOPLE magazine that she thinks her daughter is ''way cooler'' than her, and credits Willow for making her re-evaluate her life.

She said:''It's like starting over in a way - really healing and wondrous, and you're reminded constantly how sarcastic and how presumptuous you can be, and how hardened life has made you,

''That innocence is so worth protecting. That's a really long-winded answer for, 'She's way cooler than I am.'''
