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

It took the Los Angeles Fire Marshall to contain the eager crowd that showed up for Justin Timberlake’s pre-Grammy concert at Avalon. Even VIP’s Nick Lachey and Vanessa Minnillo, Rosario Dawson and Taryn Manning had to make tracks to get inside before the doors closed. Fresh from her own pre-Grammy bash at the Avalon the night before, Fergie arrived to support Justin. “Crazy week!” she said of the pre-Grammy hoopla as she walked into the party. “I cant pick, there are so many!” the lady Pea replied when a reporter asked her to name her favorite JT song. "I like “Where’s the Love,” the song I did with him!” Fergie kept the party going at the Clive Davis bash the next night.
