Justin Timberlake Grows Out His Curls For ‘The Social Network’

JT explains that he's growing his hair for the upcoming Facebook movie.

Did [artist id="1231683"]Justin Timberlake[/artist] forget to get a haircut before his benefit concert in Las Vegas on Saturday night? How else to explain the presence of JT’s curls in place of his usual close-cropped look?

“My hair is obviously growing out for a reason,” Timberlake hinted to MTV News at the red carpet for the event.

That reason is “The Social Network,” David Fincher’s take on the creative forces — and salacious backstabbing — behind the founding of Facebook. Filming is set to begin soon in Boston, and Timberlake has been preparing for his role by skipping a trip to the barber shop and growing out his ‘do.

He will be taking on the role of Sean Parker, a Napster co-founder who helped Mark Zuckerberg grow Facebook after its launch at Harvard. In the book on which the film is based, “The Accidental Billionaires,” Parker is presented as an ego-swollen party boy, part Silicon Valley wheeler-and-dealer, part see-and-be-seen nightlife maven. After assuming the mantle of Facebook president, Parker was forced out after a falling out with founder Mark Zuckerberg in what was just one of the many personal squabbles and breakups shadowing the company in its early years.

“Zombieland” star Jesse Eisenberg will play Zuckerberg. “The West Wing” vet Aaron Sorkin adapted Ben Mezrich’s “Accidental Billionaires” for the screen, with Kevin Spacey stepping into an executive producer role . The last time we spoke with Spacey, he didn’t envision himself appearing onscreen, though he did star in another film based on a Mezrich book, last year’s “21.”

“To be honest, David Fincher is so ridiculously genius that we’re all just following his lead,” Timberlake said. “I think we want to tell the story, and I want to tell it through Sorkin’s words and Fincher’s eyes. I think Aaron did a lot of research on all of it. I don’t want to speak for another actor, but I think the consensus for all of us is that we just want to make a great film.”
