Thankfully, she's back and better than ever on the cover of the January issue. The editorial, shot by Mario Testino, is incredible (natch). But what we're really loving is the Cass Bird-shot video, which is a hilarious send-up of New Age "yummy mummy" culture. Miller shows off her acting chops (oh yea, that's what she does to be famous!), waxing poetic about "feminine energy," feeding her kid only organic purée and finding her inner child.
Welcome back, Sienna. We're glad to see you on Vogue again — even if there are more interesting cover stars to be had (*cough, Kerry Washington, cough*).
