The 'Problem' singer has been donning a lot of cat ears recently and this selfie was no different.
Emebllished with teeny tiny roses, Ariana's cat ears featured pearls and lace, making these the girliest pair our eyes have ever seen!
As always, Ariana wore her locks in her trademark high ponytail to show off her flawless complexion. She also emphasised her brown peepers with mauve shadow, fluttery lashes and a feline flick.
But what we loved most about this look was her amazing purple lippy! Little Mix's Perrie Edwards is a big fan of this hue and it looks like Ariana is also enjoying this bold shade.
And with Halloween celebrations popping up everywhere over the weekend, we reckon this is a fab look for any spooky celebration.
If you fancy having a go, pick up MAC's lipstick in Violetta (£15.50) to purple your own pout. We love this number as it's guaranteed to deliver a colour just as intense as Ariana's.
Or, if you find lippy tough to put on, grab Sleek's super cheap Matte Me Lipstick in Fandango Purple (£4.99). It applies like a lipgloss but dries as a matte lipstick, plus its staying power means it'll keep in place all night. Even after a Halloween cocktail or two!
Either way, just make sure you apply a conditioning lip balm like Burt's Bees Beeswax Lip Balm (£3.69) to keep your smackers super soft.
Then just grab your favourite cat ears to complete your transformation to super glam kitty à la Ariana!
