She’s not the only to favour this neat trick. Liv Tyler does, too. Her lipstick of choice? Givenchy’s Rouge Interdit in Poetique Iris. ‘I dab it on my lips with my fingers, then use what’s left on my cheeks,’ she told me. Liv’s lipstick’s not on counter till 15th August but to tide you over, here are some others that work beautifully:

Delicate Velvet Finish Lipcream in Fuschia, £7.82, by Bourjois. This gives a natural-looking flush and its semi-matte texture makes lips look plump.

Armani Silk High Color Cream Lipstick in number 4, £19, by Giorgio Armani – this bright pink looks brilliant with a tan.

Perfect Rouge in PK307, £18, by Shiseido. This pale pink looks pretty on lips, dewy on cheeks and it perks up pale skin beautifully.

Bonus: matching lips and cheeks makes you look instantly pulled together – ideal for travelling or making up in a hurry.
