So you know how some things start out as a TOTAL rumour but then they turn out to be true — kinda like Gaga's is-she-or-isn't-she Monster fragrance — well this is a little gem of a rumour that the Elle girls started that we're soooooooo hoping will come true: Stella McCartney makeup. Sigh. Just imagine. It will be all dewy skin, perfect pinks and vegan goodness. So how did the rumour mill get a-churning? Well. Gwynnie P asked her gal pal Stella to talk about an average day being a busy working mum and generally fabulous person. In it she talks about having a meeting with YSL Beauté (the team who help make her fragrance a reality). She talks about "working on new bottle design and outer packaging for the Stella Sheer fragrance," — cool, but now ground-breaking — but it's the "top secret" stuff we want to know about. The YSL peeps came over from gay Paree; there's "an agenda from hell"; Stell says it's totes hardcore. Which can mean only one thing: a makeup line is in the works, no? Please say it's so, Stella.
