Parties! The style, stars and scoop from Hollywood's hottest events

The circus came to town when Sienna Miller hosted a party at Canadian department store Holt Renfrew to introduce fashion fans north of the border to her new Twenty8Twelve line. Stilt-walkers and fire-jugglers lined the red carpet entrance and inside it was an equally wild scene. Behind the plush red velvet curtains of the VIP room, ringmaster Miller played host to celebrity friends like Sean Penn, Maggie Grace and Liv Tyler. Emile Hirsch eyed the super-sweet buffet table offering sugary delights like mini ice cream cones and oversize lollipops. "We love the Oliver Twist era, so this circus theme ties in very nicely," said Sienna’s sister and co-designer, Savannah Miller. "Sienna and I are inspired by Dickensian London and all that kind of backstreet weirdness that went on at the time."
