And they went perfectly with her rainbow hair.
Now, we've heard of matching your lips and nails or your shoes and handbag (obvs), but matching your hair with your nails is a new one – even to us!
The 'Hard Out Here' singer popped in to Radio 1 on Tuesday morning (15 July) to perform her latest single 'URL Badman' on the Live Lounge with Fearne Cotton.
Dressed down in a baseball jacket, ripped skinny jeans and white heels, Lily looked as cool as ever with her pink hair growing out into a rock 'n roll blend of dark roots, purple and pink lengths and almost-blonde ends.
And the nails, oh the nails...
We love a multi-coloured mani (Jessie J showed off fabulous, multi-pastel nails earlier this year), but a multi-coloured, ombre mani? Lily, you've nailed it, again!
Sporting every pastel shade under the sun and perfectly blending her colour pairs, we literally couldn't love Lily's look more.
Sadly, painting ombre nails is not an easy technique to perfect (we're yet to get it spot on), but you could copy her look by investing in some different shades of ombre falsies and mixing them up.
We love Elegant Touch False Nails in Tropical Sunset, £7.10, superdrug.com and Woo Woo, £7.10, superdrug.com.
Or if you really want to work the rainbow, Lily-stylee, get involved with some customised WooWoo Nails.
This clever little nail company offers design-your-own nail wraps so you can choose your various ombre colours and get them delivered straight to your door.
Yes, yes, YES!
