Zac Posen launched his collection for Target in New York, and Clare Danes, Maggie Gyllenhaal, Olivia Palermo and Selma Blair were all on hand to help him celebrate, and Selma and Claire even sported pieces from his range. And, not content with attending just one party Olivia and Claire then skipped over to the city's Natural History museum for its annual dance.
Across town Jessica Alba, Camilla Belle and Kate Bosworth all turned out for the opening of the new Tod's boutique. Jessica and Kate both looked ultra chic in black, while Camilla rocked a right-on-trend cream and grey digital print dress.
And the model contingent was out last night too. Lily Donaldson worked laid back cool in a denim shirt and fedora at the Isabel Marant store launch, while here in London Kate Moss stepped out in a pair of leather trousers.
