"The Lip Bar Liquid Matte Lipstick in Rebel (£11) is a beautifully rich, deep burgundy that lasts for 8-12 hours with its non-drying vegan formula," said Cooper, who also shared her top tip for ensuring your lipstick looks as flawless as the lips in this picture. "For a smooth finish that won't crack, exfoliate your lips, apply a kiss of lip balm, and then blot off the excess prior to application." Unfortunately, Lip Bar is only available in the US for now, so add it to your wish list for the next time you or a friend makes a trip across the Atlantic.
