Justin Timberlake on 'Social Network' Set -- FIRST PICS

A clean-shaven Justin Timberlake is ready to get down to business on the set of his new movie, The Social Network, on Monday (November 9) in Los Angeles.

The 28-year-old singer and actor will play Sean Parker, co-founder of Napster, in the Aaron Sorkin film.

JT will work with Adventureland‘s Jesse Eisenberg, who portrays Facebook guru Mark Zuckerberg.

“I’ve been doing research about the film,” Justin told Extra. “I’m starting to creep on a little bit more and see what it’s all about.”
