If, like us, you've been listening to Taylor Swift's new album Reputation on repeat since Friday, you probz know the lyrics off by heart, yeah?
So if we were to ask you which song the lyric: "X marks the spot where we fell apart" is from, we're sure you'd probz say "Getaway Car, right?
Well it turns out that this is also a lyric from Hilary Duff's 2015 song "Breathe In. Breathe Out."
This isn't the first time that Swift has been accused of stealing lyrics. Back in September she came under fire for supposedly taking her "Shake It Off" lyrics from noughties 3LW track "Playas Gon' Play".
Meanwhile, fans of the Younger and Lizzie McGuire have taken to Twitter to blast Tay for knocking off Hilary's lyrics.
