Rashida Jones logs into 'The Social Network'

The charming Rashida Jones is the latest to join David Fincher's upcoming Facebook movie "The Social Network," which is currently filming for Columbia Pictures with a release set for Oct. 15, 2010.

Variety reported the news about her involvement, but at this point it's unclear what character she will be portraying. Aaron Sorkin's script centers on how Facebook evolved into a site with 300 million users.

Jesse Eisenberg plays Facebook CEO Mark Zuckerberg, while Justin Timberlake will play Napster co-founder Sean Parker. Andrew Garfield will portray Eduardo Saverin, one of the site's co-founders.

Jones, whose credits include "The Office" and "Parks and Recreation," recently starred in "I Love You, Man." She will star in Dana Adam Shapiro's "Monogamy" opposite Chris Messina.
