The lyrics go: She got, she got, she got)
Her own reason...for talking to me
She don't, she don't, she don't...give a fuck
About what I need
And I can't tell you why
Because my brain can't equate it
Tell me your lies
Because I just can't face it...
Hmmm - Are the lyrics about his split from Perrie?
