The Les Misérables actress rocked a vivid blue and red colour block dress by Roksanda Ilincic for the opening of the new flick, in which she plays the voice of Jewel.
But aside from her fabulous frock, it was Anne's vibrant smackers that really caught our attention.
Anne tends to play it safe on the beauty front, usually sporting flicked liner paired with a nude pout or Hollywood red lippy.
But this time the starlet delved into her make-up stash and pulled out one of our favourite hues - fuchsia pink!
The actress teamed her loud smackers with a rosy flush on her cheeks, along with subtly-defined eyes and bold brows.
So, why do we love this shade so much?
Well, firstly it's a fave of Khloe Kardashian (and that's saying a lot).
Secondly, it's the perfect popping hue to perk up your complexion for summer, and it looks incredible with a tan.
And thirdly, it's great for those days when you've overslept and need to get ready - fast. Simply pair with lashings of mascara and you'll look like you've put a lot more effort into your make-up than you really have!
Our fave pinks? MAC Lipstick in Impassioned, £15, which is a super-bright, almost neon shade.
We also love Revlon ColorBurst Lacquer Balm in Vivacious, £7.99, which gives a glossy finish in a handy crayon form.
Team with lip liner (try Barry M Lip Liner in Fuchsia, £2.99) to create a smooth surface and help keep your lippy in place 'til lunch!
