The mother-of-two showcased sunny talons while attending the Saving Mr. Banks premiere at the BFI London Film Festival yesterday (20 October).
Lily has been seriously impressing us with her nail looks recently – we loved her ombre animal print nail art, not to mention her fierce duo-chrome pointed talons.
Now the singer has swapped the fancy designs for a single wash of eye-popping neon yellow.
Her vibrant mani gave her black and white gown instant zing, and complemented her transparent Chanel 'Lego' clutch perfectly.
And it looks like Lily has been loving the zesty colour for a while, tweeting: "It seems I cannot get enough of the flouro yellow, it's been like a month!!!"
Get her look by applying a base coat, before lacquering up with China Glaze Nail Polish in Sun Kissed, £6.95. We also like Jessica Nails in Yellow Flame, £9.75.
Keep a cotton bud dipped in nail polish remover on hand to clean up any mistakes, then finish with a glossy top coat.
Chanel arm candy optional (but highly recommended!)
