Mills took to Instagram earlier today to reveal the unlikely hair trend she is obsessed with at the moment but you'd be a fool to think that it's a Khloe Kardashian-inspired lob or a tight top-knot like Kendall Jenner's.
The look in question? Pigtails, of course!
Make-up-free Millie posted a cute car selfie in which she rocked two dishevelled pigtails secured by a simple black hair tie, proving that she isn't as high-maintenance as we all think - and even though we haven't rocked them since our primary school days, we're just a little bit in love...
Oh, the nostalgia.
Millie captioned her snap, "Bring back pig tails," and it wasn't long before her followers took to the comments section.
One of her fans wrote, "I might try them in the office tomorrow and see if they do me any favours," while another said, "Yes! So cute!"
We can't deny that Millie's new look is perfect post-gym or when you don't have time to straighten your tresses in the morning, but it's also painfully reminiscent of the altercation between poor little Amanda and Miss Trunchbull in Matilda...
