A video posted on Twitter shows Perrie and her bandmates performing in New Zealand and many fans are claiming the singer makes a subtle - yet very important - change to the ‘Shout Out To My Ex’ lyrics.
Instead of singing, “Hope she ain’t fakin’ it like I did”, a number of Twitter users reckon Perrie says, “like Hadid”.

Honestly? We’re not so sure, but here’s what the good people of Twitter are saying…
In the weeks that followed its release, it was also claimed that the track almost included a more explicit reference to Zayn and Gigi’s new relationship.
