Hackers have broken into Salma Hayek's email, revealing the actress's iPhone-app obsession, designer-clothes habit, travel plans, and more. (Her billionaire husband, François-Henri Pinault, who's throwing a second wedding for her this weekend, pays the bill!)

How could one possibly make Twitter even more of an exercise in self-absorption? How about by broadcasting yourself on national TV while using Twitter? Oprah's big Twitter show is on right now and we're watching.

Who is Lindsay Lohan turning to after her breakup with girlfriend Samantha Ronson? Patrick Aufdenkamp, her stylist pal, looks to be making his move.

Blogs, Facebook, and Twitter were supposed to liberate famous people from old-media gatekeepers. But John Mayer, Courtney Love, and others are teaching us that public figures are terrible at shaping their own image.

A LiveJournal user says the brilliant mind behind the crazed tweets of celebrity mom Dina Lohan is a 24-year-old Michigan man named Matt Cherette. Cherette, who's confessed, has a career in Hollywood awaiting him.

A fashion designer has sued wacky-mess rocker Courtney Love for libel on MySpace. Love's response? Going on a blabby Twitter rampage and accusing Lindsay Lohan of stealing drugs.

Either Lindsay Lohan's entire crazy family is really on Twitter, or the world's best comedy writers have taken to the medium. Here are Dina Lohan's Twitter tales of bad tea, insidious censorship, and "HATERS."

How do you know all those tweet-happy celebrities are the real deal? 50 Cent, Keith Olbermann, Christopher Walken, and Britney Spears are just a few of those with questionable Twitter identities.

It turns out using Twitter will not get you laid. Actress Jennifer Aniston reportedly dumped musician John Mayer over his habit of broadcasting his every idle thought on the microblogging service. Hurray!

Kim Zolciak, the homewrecking, fake-cancer-surviving star of The Real Housewives of Atlanta has lost control of her blog to a surly "webmaster" demanding payment — according to someone at her (former?) PR firm.

Celebrities on Twitter, they're just like us! Shaqille O'Neal, the Phoenix Suns basketball player, has instructed Twitter users that as "citizens of Twitteronia," they should feel free to bother him in public anytime.

In between fielding calls from the CIA and praising "Love and Light," internet-savvy whippersnapper Ashton Kutcher procured an "assistant" (virtual?) to introduce wife Demi Moore to Twitter. Moore's already getting snarky.

That's hot. Paris Hilton's official website is unsafe for browsing, computer-security researchers have declared, playing host to software which tries to hijack her fans' bank accounts. Doesn't the heiress have enough money?

It takes just one crack about Britney Spears's vagina's "razor-sharp teeth" on her official Twitter feed — a juvenile stunt by a hacker — and her entire social media operation is thrown into disarray.

Unconspicuous consumption is the hot new thing. That $300 million megayacht? Tacky, what with the layoffs. Private jet? Forget about it, after Detroit's debacle. Even the celebrity goodie-bag business is endangered.

Whats going on with Twitter? First Fox News gets hacked, then Britney Spears. Is no one safe from this epidemic?

John Travolta and Kelly Preston have two nannies. Jeff Kathrein, the one who found the dead body of the couple's 16-year-old son, Jett, was caught kissing Travolta. Who's the other one?

Did Travolta hire his unqualified gay lover to care for an ill child, who then died on the faux nanny's watch? If so, you won't read about it in the trashiest of Internet tabloids.

Kristin Davis, whose Wicked Models escort agency counted former governor Eliot Spitzer as a client, thinks Britney Spears could earn $1,000 an hour in the world's oldest profession.

What did comedian Michael Ian Black do to get banned from Facebook? I'd like to think it was karmic payback for providing the voice of the Pets.com sock puppet, an enduring icon of dotcom disaster.
