When I buzzed Chanel make-up artist Mary Greenwell to find out how to re-create the look, she was gushing as much as I was. ‘There’s perfect balance in this look,’ she said. ‘There isn’t one feature that screams louder than the rest. It’s pure but polished and executed with a great sense of colour.’

Here’s how to DIY:

Step 1. ‘Create a soft, flawless base using Chanel Teint Innocence in Faience, £25, then dab Chanel Eclat Lumiere in Beige Claire, £23, from the inside corner below your eyes, all the way under your eyes and right out across your cheek bones and up to your temples. This opens up the whole eye area dramatically.’

Step 2. ‘It’s the grey eye shadow that makes this look interesting. Start with a sweep of pale pink shadow over the entire lid up to the brow bone, then blend a good, true grey along the upper and lower lash lines, over your lids and through the socket. Chanel Les 4 Ombres in Mystic Eyes, £33, has the perfect shade – slatey but soft.’

Step 3. ‘Lily’s worked her eyebrows with plenty of brow pencil so they look really defined. But she’s kept it soft by choosing the perfect shade and blending it well.’

Step 4. ‘There’s only one thing to use for cheeks like these and that’s Chanel Joues Contraste in Fandango, £26. It’s somewhere between a blush and a bronzer, meaning it gives a gorgeous, glow-y flush but can also be used for contouring. Plus, it’s a suit-all shade that looks great on everyone. Blend it into the apples of your cheeks for rosiness, then sweep your brush under cheekbones and over the whole area to add definition.’

Step 5. ‘Lily’s lips are an irresistible shade of peachy pink with just the right amount of gloss. It’s not available just yet [check out counters in early March] but you’ll get a similar look with Chanel Rouge Allure Laque in Ming 76. It’s a tender pink that gives the polish of a lipstick with the freshness of a gloss.’

So it’s good new for us – a gorgeous new look to try out – and it’s good news for Lily: when she gets too old to be a model, she can become a make-up artist.
