Katy Perry apologised to her parents after swearing on the Grammy Awards red carpet.

The 'Chained to the Rhythm' singer slipped up after getting carried away while discussing her upcoming new album on Sunday (12.02.17), prompting her to joke she'll never be invited back to the prestigious ceremony.

Speaking to Ryan Seacrest, she said: ''[The album has] got a wide range of feelings and emotions. I just feel a little bit more conscious than I've ever have and kind of worked out some of my s**t.

''Oh! Sorry! I'm live! I still didn't stop swearing obviously.

''I'll never be on this show again -- goodbye live! Well, sorry mom and dad!''

And the 32-year-old pop star also sparked outrage for appearing to mock Britney Spears - who infamously shaved her head during her 2007 meltdown - when discussing what she's been doing in her break from the spotlight.

She said of her time out: ''Yeah, that's called taking care of your mental health. [It's been] fantastic and I haven't shaved my head yet!''

And Katy also made similar remarks when discussing her new blonde hair cut.

She said: ''It's the last colour in the spectrum that I can do, I've done all of them and the only thing left to do is shave my head which I'm really saving for a public breakdown. I'm down for that.''

Away from controversial subjects, the 'Dark Horse' hitmaker explained how she is ''proud'' of her new music, which is more thoughtful and she hopes will spark conversations.

She said: ''I'm so proud of it. I think it's a new era of me. I call it an era of purposeful thought.

''All of my songs have always had layers to them ... I used to be kind of the queen of innuendos and I woke up and educated myself more and I think I'm maybe more the queen of subtext and I think it's a song that starts conversations ... and I think we need to listen to each other.''

However, she insists that doesn't mean it will be a sedate record.

She added: ''It will make them move. There's going to be all kinds of stuff on there and don't worry, you're going to have some of that gold old Katy Perry fluffy stuff that you love so much.''
