The star, whose signature makeup look is usually statement red lips and a simple flick of black liner, shifted the focus to her blue eyes with dramatic effect. Here's how to steal her look:
1. Apply a shimmering bronze eyeshadow to your lids starting at the lash line and blending up towards the socket.
2. Apply a gold eyeshadow beneath the lower lashes as close to the lash line as possible.
3. Line the upper lids with a thick line of black liquid liner. Draw the outer edge with the tip of the brush and then fill in.
4. Apply a volumising mascara to the upper and lower lashes.
