Kelly was first to adopt the look but Little Mix's Perrie has managed to put her own stamp on it since then.
Perrie may or may not have taken her hairspiration from Kelly, or even Katy Perry who rocked the look way back when, but does it matter?
The Fashion Police presenter says a big fat no, taking to Twitter yesterday, "So sick of having to defend #PerrieEdwards in interviews. Who cares if she has the same hair as me I think she is adorable I <3 Little Mix!"
Are you a fan of the purple hair trend? Who do you take your hairspiration from?
