Director David Fincher's critically acclaimed box office hit 'The Social Network' comes out on DVD and Blu-ray on Tuesday, and ET was at the launch party! Looking behind the scenes, Justin Timberlake explains how his wardrobe helped him inhabit the character of Napster founder Sean Parker.

"My first wardrobe fitting was at the Armani store in Beverly Hills. It was kind of amazing to have Armani making your wardrobe," says Justin. "It makes a difference in how you walk, and that makes a difference in how you talk, because it changes your timing."

Costume designer Jacqueline West did extensive research and explained to Justin how Parker had all of his clothing custom-made by Giorgio Armani.

"They really went all the way out -- I mean, [the label on the inside of my jacket] says Giorgio Armani for Sean Parker," says Justin with a laugh. "It's amazing these days what you can find out about someone when you have to play them in a film."

Available Tuesday, January 11, with more than eight hours of bonus features on the Blu-ray and DVD, 'The Social Network' stars Jesse Eisenberg as Facebook founder Mark Zuckerberg in a story that investigates the possibilities of whether or not the Harvard computer genius stole the idea for the social network that made him the world's youngest billionaire. Parker stepped in early on to help guide the company to greatness.

The film, poised to cross the $200 million mark at the worldwide box office, is also being re-released in approximately 600 theaters nationwide today. To date, the film has grossed more than $93 million in the U.S. and $104 million overseas.
