Yves Saint Laurent's Online Casting Call...

Paul Smith celebrated five years on Melrose Avenue with a 325-person bash at its pink box of a boutique Thursday night. Multigenerations of music types — from producer Andy Slater to Michael Des Barres to Ione Skye and Kelly Osbourne — came out to lounge in the outdoor living room around a bonfire, while nattily dressed gentlemen like Greg Gorman and Skye’s husband, Ben Lee, perused the shop. The crowd did put down their Champagne to take in an a cappella performance by The Silver Lake Chorus, whose first album, produced by Lee, will contain tracks written by Beck, Zooey Deschanel and Aimee Mann.Yves Saint Laurent sent a shout-out through cyberspace Tuesday for 130 extras — tall, elegant “beautiful people” — aged 25 to 50 to be in an advertisement. Sources say it’s for a YSL fragrance. Castingdujour.com e-mailed the announcement, explaining the casting is expected to take place this week and that the shoot will happen over one day between Dec. 13 and 15 in Paris and its environs. The pay will be 150 euros, or $200 at current exchange.
