Pink has finally realised how many swear words are in her songs since she became a mother.

The 'Blow Me (One Last Kiss)' singer never tones down her language on her tracks, but now she has 15-month-old daughter Willow with husband Carey Hart, she realises why some of her music is not suitable for children.

In an interview with the Herald Sun newspaper, she said: ''I'm a mamma I'm more aware of it. I get it. I get it why my friends are p***ed at me when they have kids in the car and my songs come on. Sorry!''

The 33-year-old star adds her record company are always trying to get her to re-record more family friendly versions of her tracks, but she doesn't see the point.

She added: ''The record company always say, 'Have you got a clean version?' And I say, 'No, just f***ing bleep it.' ''

Referring to the chorus of 'Blow Me (One Last Kiss)', which features the line ''You've had a s**t day,'' she added: ''I wasn't going to sing 'You've had a rough day / I've had a rough day.' Not gonna happen.''

When she goes on tour, Pink also joked she'll be getting her baby to fit in with her own party-heavy schedule.

She said: ''When you're in my world you're going to bed at 2am. So is Willow!

''Now she'll go to bed at nine so she can sleep through until at least 7am. Well, that's the plan.''
