Well this is interesting, I am not a obsessive MAC fan anymore but this collaboration sounds interesting.
This is the public announcement that MAC published regarding the collaboration:
Irreverent and a living image of provocative fashion – Carine Roitfeld. M·A·C announces our collaboration with the fashion visionary and muse, editor and image-maker. M·A·C partnered with Carine on every aspect – from the chic shades and Good Luck Star to the packaging and the tools to achieve her signature look – nude lip, bold brow, and the smoky eye elevated to a new art form. Photographed by Mario Sorrenti. Debuts this Fall.
