According to GQ, Justin Timberlake is one of the 10 Most Stylish Men of the year. So, it's fitting that the singer is one of the forces behind the William Rast clothing line, which he started a few years back with his childhood friend and business partner, Trace Ayala.

Timberlake, along with his design partners Johan and Marcella Lindeberg, made the line's big debut at the Bryant Park tents during New York Fashion Week. For their fall 2009 collection, Timberlake told MTV News that he found inspiration in the "new America" — making it rather appropriate that the show took place on Presidents' Day.

"Birth of a new leadership, birth of a new era, birth of a new culture," he said. "And I think being who we are as a brand ... I think it inspired us to take it beyond where we were. So, that's it — a new America."

Timberlake explained that he manages to find time to design a clothing line — in addition to his work as an actor, producer and musician — because of the great team behind William Rast.

"Well, [music and fashion are] both collaborative, just in different ways," he explained. "Johan and Marcella Lindeberg are such an intricate part of this line, [from] the birth of it to where it is now — where we are. ... I think it's interesting."

Although he is very hands-on in the design process, for him it's more about being an ideas man than actually sewing clothes together. "The way I work with them is [I] give them ideas on lifestyle," he said. "Not so much specific clothing, 'cause that's what they're so good at — taking a general idea and throwing it into specifics and making it a part of the clothing; that is that lifestyle."
