Sienna Miller hosted the grand opening of the Esquire House in LA on Friday night. She arrived on the West Coast late last week before joining fellow blond Kate Bosworth for the philanthropic event. Despite being on the rumored guest list, Jude Law didn't attend and instead stayed in London to hang with his Sherlock Holmes friends over the weekend. Alexander Skarsgard accompanied Kate to support the cause and the two followed their charitable night out with a trip to Saturday's Spike Scream Awards, though Kate stayed out of the spotlight while Alexander took home the statue for Best Horror Actor.
