This morning, WWD reported that Piaget would kick off a viral campaign in honor of Posession's 20th anniversary today. The newsy bit said Sienna Miller starred in a few images released both on Piaget's homepage and Facebook account, as well as a promotional video in which she wore a few rings and strands of necklaces.
That video, however, stars a model named Maria Gregersen. The only celebrity currently appearing on Piaget's homepage is Taylor Momsen. What is on the site is a mystery, "An exceptional abassador for an exceptional celebration," it promises, "Who is she?"
The type is set against a woman's silhouette, and on Piaget's Facebook page there's a "Guess Who?" click through option on which you can see various blurred images of a woman as well as videos in which Elissa Santisi and others on the shoot talk about the mystery model (and you catch a glimpse of Sienna's three star tattoo).
But as of this morning, Sienna Miller isn't named on either site which must mean her identity is supposed to remain a mystery.
