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

The swank Beverly Hills Hotel was atwitter when celebrity guests Patricia Arquette, Michelle Trachtenberg, Garcelle Beauvais-Nilon, Kelly Hu, Melinda Clarke, Jenna Elfman, Allison Janney, Rena Sofer, Tiffani Thiessen, Bonnie Somerville, Amber Tamblyn and Constance Zimmer—just to name a few—were invited to view $35 million worth of designer jewelry and some stunning gowns over an elegant lunch. Elizabeth Banks (at left with ER star Linda Cardellini) couldn't decide which element she was most looking forward to. "I love looking at ice, and pairing the dresses with the jewelry is so fun," she said. "And I love a good girly lunch."
