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

On Sunday, cast members Emily Watson, Ewan McGregor and Renée Zellweger reunited for the premiere of Miss Potter in New York City. Zellweger wore a cocktail dress by her designer of choice, Carolina Herrera, and accessorized with Manolo Blahnik heels and plenty of diamonds from jeweler Van Cleef & Arpels. Asked about his red-carpet style philosophy—and his black and white patent-leather footwear—McGregor swore he was just trying to keep it simple. "Most of my stuff's back in London," said the actor, who plays Miss Potter's book publisher in the film. "So I just put on what I had!" After the credits rolled, the trio enjoyed a civilized celebration at hip night spot the Grand.
