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

Everyone felt the LOVE when renowned jeweler Cartier hosted the annual unveiling of their charity bracelet collection and LOVE Day celebration at a private manse in Beverly Hills. Among the Hollywood luminaries who showed up to unveil their bracelets—which will support the cause of their choice—were socially-conscious stars Janet Jackson, Fergie, and Hilary Duff. "A lot of children will be thankful because of the plans we have [for the money we'll raise]," said Joel Madden, whose deep green link of love will support his and girlfriend Nicole Richie's own Richie-Madden Children's Foundation. "It feels like Valentine's Day in June."
