Applying lipstick during your day might not mean breaking news, but if you're the model simply known as Kate, it's enough to make the fashion folks flap their lips for months.

Such was the case when supermodel Kate Moss was photographed last October en route to Paris Spring Fashion Week while applying a Dior Addict Lipstick in Charmed Pink No. 578 -- the iconic silver bullet instantly giving away the identity of her choice of brand.

The fashion world literally went a-Twitter, surmising it would only be a matter of time before the 37-year-old Brit partnered with the French luxury brand, a match seemingly made in couture heaven.

And now months later, it's finally official: Dior Beauté has announced Moss will flaunt the brand's Dior Addict lipstick line, which the model has already made famous with her October paparazzi shot.

In a video tease for the ad campaign, which will debut in May fashion magazines, we can see that Ms. Moss still prefers to step out in a classic pink shade on her famous lips -- and in a pair of sky-high Christian Louboutins and a deep black mani. Urban backdrop of choice? Paris, mais oui.

A long time celeb and socialite favorite, the Dior Addict lipstick line is a high-pigment color collection that boasts creamy, stay-true shades. There is also a High Shine grouping of the line that offers sheerer, translucent shades with a more lip-balm-like feel.

But the fashion world is already onto its next Kate Moss rumor: Is that an engagement ring on her finger?

For a lady who likes to stoke us all with a tease and nary a confirmation, we have a feeling it'll only be a matter of time before wedding bells are ringing for Moss and her Brit guitarist beau, Jamie Hince.

We do know this: The perfect lipstick for her day of bliss will be only a pocketbook reach away.
