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

Katie Holmes welcomed Alanis Morrisette and Sanaa Lathan to L.A.'s Maxfield boutique to celebrate the launch of her Holmes & Yang fashion line. "It's very exciting," said Holmes, who paired a Holmes & Yang shirt with James Jeans. "It started with a piece of fabric." Guests sipped Perrier Jouet as they browsed the rack of clothes from the first collection, which Holmes created with her stylist Jeanne Yang.
