Meet "William Rast" -- Justin Timberlake's fashion line named for the grandfathers of Justin and his best friend and partner, Trace Ayala. On September 7, "William Rast," hits the Roseland Ballroom runway, delivering JT's very in-sync collection to the world. Then, on September 9 at 9:00 PM on CBS, JT performs at "Fashion Rocks," a star-studded concert and fashion show broadcast from Radio City Music Hall.

To introduce the collection, JT has created some short promo trailers on his website, in which the Tennessee native has cast himself in the role of William Rast, and "plays house" with gorgeous supermodel Erin Wasson in a ramshackle cabin for some chic backwoods atmosphere. Even in his black-eyed mugshot and "simulated" arrest, JT looks amazing in a leather jacket from the new line. Singer, actor, restaurateur and designer, what doesn't this guy do?!

Check out William Rast -- and the cool clothing story he tells.
