Thankfully, the former Made In Chelsea hottie spilled the beans on the exact colour she was wearing. Oh, she's a good 'un.
Ashley joined Lucy Mecklenburgh (who was totally rocking a new fringe, btw) on Wednesday night for a launch party at Notting Hill knitwear store Delam London.
And rather than just quaff champagne and eat fancy canapés at the do, our Ashley took to the decks for some DJing action!
But not before showing off her amazing make-up via the medium of our favourite source of celebrity fashion and beauty inspiration, Instagram.
"Excited to be DJ'ing at the @delamlondon launch tonight," Ashley posted.
"Shoutout to @phoebetaylormakeup for this insane makeup!" she added, along with the stunning selfie (above).
Along with the grungey hair and smudgy, rock-chick eye make-up, Ashley totally owned her purple lipstick, a look that was created by one of her favourite make-up artists, Phoebe Taylor.
The lipstick in question (thanks for your patience) is MAC Lipstick in Heroine, £15.50, maccosmetics.co.uk and is the perfect purple for Ash's creamy skin tones and blue eyes.
We also love Barry M Ultra Moisturising Lip Paint in Vicious Violet, £4.49, barrym.com which is a slightly richer tone and works brilliantly on darker complexions.
You could also try Topshop Lips in Inhibition, £8, topshop.com or for a softer, paler shade with just the right amount of purple to suit most skin tones, we can't get enough of Nars Audacious Lipstick in Dominique, £24, narscosmetics.co.uk.
As Prince once said, purple reigns. Sorry.
