Sienna Miller is all smiles for her second American Vogue cover, shot by Mario Testino.
I'm not terribly familiar with Sienna Miller's work. I only barely remember her in that GI Joe film, and otherwise only know that she's engaged to Tom Sturridge (lucky). She basically seems like another generic blonde actress to me.
The cover is nice; the colors are complimentary, and she looks pleasant. The editorial is typical Testino, and therefore rather dull. I do wonder who all those children are, though. Wikipedia says Sienna's only got one daughter.
