L.A. fashionistas gulped Borba water and Han vodka-infused cocktails while perusing the racks and eyeing the glittering crowd. Lauren Conrad, clad in Elizabeth and James, created a flashbulb frenzy when she showed up on the red carpet with constant companion Lo Bosworth. (Don't worry, the duo met up with Audrina Partridge once inside.) Recent West Coast transplant Jamie-Lynn Sigler was also in attendance, dressed in a Calvin Klein tank paired with a Zac Posen high-waisted skirt. Sigler gushed to me about her upcoming role on Entourage (it's been reported that she'll be playing the love interest of one of the guys). "Everybody is so fun to work with, and we have such an amazing time on set," she said, while also giving a shout out to the store's selection of her favorite lines (Chloe tops her list). Not surprisingly, the Young Hollywood crowd mainly stuck to themselves. Kim Kardashian had her hands on her Blackberry in one corner while soon-to-explode teen sensation Selena Gomez hung on to her Wizards of Waverly Place co-star David Henrie all night.
