Justin Timberlake debuts his William Rast clothing line before a star-studded crowd

Pop star Justin Timberlake isn't your typical fashion designer. So the runway debut of his William Rast clothing line wasn't a typical fashion show.

Rather than show the collection at the official Los Angeles Fashion Week site, Culver City's Smashbox Studios, Timberlake took over one of Hollywood's hottest nightspots.

A runway and scores of bleacher seats were added to a section of Social Hollywood on Sunset Boulevard. The Boulevard3 club next door was used for the exclusive after-party, including a performance by Timberlake, the 25-year old Grammy-winner whose second solo CD, "FutureSex/LoveSounds," was released in September.

The impressive guest list included Wilmer Valderrama, Eve and Timberlake's girlfriend, Cameron Diaz, who gave interviews and posed for pictures before taking their front-row seats. Other A-list attendees included Paris and Nicky Hilton, Maroon 5's Adam Levine and Patrick Dempsey, aka Dr. McDreamy from TV's "Grey's Anatomy."

When the show got started, David Bowie's "Rebel Rebel" blared as models with their hair styled into pompadours and makeshift mohawks previewed the spring 2007 collection dubbed "Street Sexy." Timberlake started William Rast less than a year ago with his childhood friend Trace Ayala. They named the brand after their grandfathers.
