That was fast: Six months after he started seeing Alexandra Lenas, Sean Parker is engaged to the singer/songwriter. Parker has made a number of sudden life changes since Justin Timberlake played him in The Social Network, actually.

Alright: the latest Forbes' billionaire list is out. Now we can all get out our Sharpies and draw circles around which billionaires we're gonna date this year. Kidding: billionaires only date other billionaires and underwear models.

When Justin Timberlake was preparing to play Napster inventor and early Facebook investor Sean Parker in The Social Network, he asked for the real-life Parker's help and was famously rebuffed. Makes sense: Post-Social Network, Parker isn't happy at all with his newfound fame.

Did James Franco enact the most satisfying zit-popping known to man after the Oscars? Rob Pattinson and Kristen Stewart make out on a dance floor. Bieber and Selena Gomez make love with their hands. Melissa Leo rather regrets dropping an f-bomb. Monday gossip is an Oscars hangover.

Sean Parker and Dustin Moskovitz have donated a total of $170,000 to support California's Proposition 19 to legalize marijuana. In so doing, the old friends of Facebook CEO Mark Zuckerberg have become two of pot legalization's best friends.

It's just like old times: After being ejected from Facebook after a cocaine-related arrest, Sean Parker worked hard to cultivate a more upscale image. But now comes news he flipped out at a New York nightclub doorkeeper. Whoops.

Who would have thought the Facebook movie's breakout star would be Justin Timberlake? Apparently the singing, dancing, tequila-brewing genius put out a surprisingly strong performance in The Social Network. Well enough, maybe, to take an obscure nerd international.

Justin Timberlake needed some help preparing for his starring role in the forthcoming Facebook movie The Social Network. But when the young singer approached Facebook co-founder Sean Parker in a nightclub, seeking acting help, he got shot down.

Facebook's first president, former Napster cofounder Sean Parker, was pushed out of the company in 2005 at the insistence of Facebook VC Jim Breyer after a cocaine-related arrest in North Carolina.

A forthcoming Facebook movie should further Sean Parker's reputation for enjoying coke-fueled parties with college coeds. Maybe the celeb-studded soirees he's been throwing at his $20 million Manhattan mansion, Bacchus House, will class up the Facebook co-founder's rep a bit.

New pictures from the Facebook movie's set have none other than script-originating novelist Ben Mezrich uncertain how he feels. With clips from corresponding portions of the script, we decipher Mark Zuckerberg's sleepy-time befuddlement and Timberlake's alpha male "fuck you."

• Courtney Love has lost control of her daughter. Frances Bean Cobain is almost an adult—she's 17—but a LA judge has granted guardianship to Kurt Cobain's mother and younger sister yesterday. Don't think it's because Courtney is on drugs or completely crazy (although she is). It's just that Frances is a…

It's always been tough to imagine Justin Timberlake fitting into a movie about the geeky origins of Facebook, even if he was slated to play hard-partying advisor and "founding president" Sean Parker. That mental struggle is over.

Well, the contentious rumors have been confirmed: Justin Timberlake will play founding president Sean Parker in a little film entitled The Social Network, which everyone else just calls "that Facebook movie." Meanwhile, Jesse Eisenberg will play founder Mark Zuckerberg. [AFP]

The blog ScriptShadow got hold of the first draft of Aaron Sorkin's Facebook movie. The verdict? The movie reads oddly mesmerizing, and has an unexpected hero: Sean Parker, an early investor in the social network.

Today at its F8 developers' conference, Facebook will announce a plan to give favored widgets more abilities to promote themselves on the site. The first two apps to get "preferred" status will be Causes and iLike. What does being a "preferred" widgetmaker mean? A source tells us that in the short term, Facebook…

HEARST TOWER, NEW YORK — Far from the sweaty, screaming fans that attended Digg's Brooklyn meetup Wednesday night, the suits of the Alley and Valley gathered last night on the top-most floor of the Hearst Tower for another Founders Club party to celebrate each others' transcendent splendor. All night, giant screens…

Sean Parker has had a hand in some of the Valley's biggest successes. His first company, Napster, took the world by storm, but didn't make Parker rich. His second, Plaxo, just sold to Comcast. And his third, Facebook — well, say no more. Except for the bit about him getting kicked out, according to Mark Zuckerberg's…

Is Plaxo going to Google, as some rumors have it? Possibly. We hear Joe Kraus, a Google executive knee-deep in its effort to catch up in social networking, skipped the company trip to Disneyland this week so he could finish a deal. But other insiders say Google's not doing a deal with Plaxo. Another plausible bidder…

It's curious that rumors of a Plaxo sale exploded at the same time that Robert Scoble got his Facebook account suspended using a secret, unreleased tool for extracting data from Facebook. Curious, too, that Plaxo is so eager to milk the incident for good PR. While a battle of words takes place in public, we hear that…
