We saw Fearne Cotton go pink and Rita Ora do blue at the beginning of the week and with Jessie also choosing a bright hair hue, it's most definitely a trend to get involved with.
Jessie had her head shaved for Comic Relief way back in March and since chopping it all off, her crewcut has proven to be a real winner.
And we love how the 'Domino' singer is proving how versatile hair even this short can be, by trying out all manner of colours including bleach blonde, baby pink and now purple.
Who needs lengthy hair and curling tongs anyway?
Jessie has never been one to shy away from adventurous hairdos and has done purple a couple of times before.
But this is definitely the best so far, don't you think?
The paler tones work perfectly with her creamy complexion and hazel eyes, and the colour is eye-popping, without being too intense.
We do hope we can look forward to more pastel colours for the rest of the summer, Jessie.
Pale blue next perhaps?
