After Hilary Duff stepped out with her green locks earlier in April...
Kylie Jenner and Jourdan Dunn showed off their blue hued hair not long after.
AND NOW
Lily Allen has followed suit by dying her hair in the rainbow shades of green and pink to mark her 30th birthday.
"Not long till I'm 30, one last hurrah on the hair front...Watermelon hurr dun care." the singer wrote on Instagram.
Has fruit ever been more inspiring? We think not.
Although Lily is the fourth celebrity to undergo a major colour transformation this month, she basically invented the trend...
Which makes it hard to believe that this really is the "last hurrah on the hair front"
What do you think of Lily's new birthday look?
Do you LOVE it or is it a step too far?
