Answer: Carine Roitfeld, former Editor-in-Chief of Vogue Paris.
Roitfeld will follow in the footsteps of Beth Ditto and Iris Apfel when she teams up with Mac Cosmetics to launch a makeup line with the brand this Autumn.
There's no word on what the collection will look like as yet, but it has been confirmed that Roitfeld will star in the ad campaign, shot by Mario Sorrenti.
According to WWD, we can look forward to a "heavy focus on the eyes and brows, mirroring Roitfeld's signature smoky eye, bold brow and nude lip".
