Katy Perry has been in the pop music industry since 2008 when she burst onto the scene with her hit ‘I Kissed a Girl’, but she’s also known for other huge hits including her 2010 tune ‘Firework’.

Now, more than a decade after its release, Katy has revealed that we’ve been singing the lyrics to her Top 5 hit wrong all this time! In a recent episode of American Idol, where Katy shares the judging panel with Lionel Richie and country artist Luke Bryan, she explained that it’s not ‘up, up, up’, it’s ‘awe, awe, awe’, and it’s not ‘fireworks’ it’s firework.

Katy shared a clip from the TV show to her Instagram account along with an excerpt from a novel called ‘On The Road’, written by American novelist and poet Jack Kerouac, which read: ‘the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue center light pop and everybody goes “Awww!”.’

So there we have it! If you want to listen to her song again here’s the music video, which has now been viewed more than 1.3 billion times on YouTube.
