Twitter

Earlier today, somebody went on Michael's Twitter page and posted several untrue statements postings which included, among other things, that Lindsay has HIV.

But Michael tells TMZ he NEVER posted those tweets -- and claims all of the hacked postings are blatant lies.

The white Tim tells us he got

Tuesday informing him they were shutting down his account because they believed he was trying to "impersonate" the Black, much taller Tim Duncan.

For some reason Twitter had a change of heart yesterday and his account was re-activated.

We reached out to Twitter and we're still waiting for an explanation ... in 140 characters or less, of course.

Sen. John McCain's voyage into the world of new technology hit a snag ... when a self-pic he posted on Twitter recently popped up (so to speak) on a notorious gay porn website.

The "Maverick" was just tryin' to show the world that he could take a pic of himself on his iPhone -- when somebody ripped the image from his Twitter page and posted it on "Guys with iPhones" -- a website featuring men clutching their phones ... and often themselves.

But McCain's press secretary wants everyone to know, the Senator is definitely not responsible for uploading his face next to all those heads ... telling us John "did not post on said website."

McCain's rep added, "As I'm sure you are aware, once something is posted [on the Internet] we no longer have control of how the photo is used."

The video for "Window Seat" was shot guerrilla-style in Dealey Plaza where President John F. Kennedy was assassinated.

Cops say a Texas woman lodged the complaint yesterday with police after she and her mother saw Erykah shooting the video completely naked.

Cops say the incident is officially under investigation and the singer could face several charges, including disorderly conduct.

Justin Massler -- who appeared in Manhattan Criminal Court moments ago -- was arrested last month after he allegedly posted a bunch of weird and threatening things about Ivanka on the Internet ... including Twitter.

The Manhattan District Attorney's Office tells TMZ an order of protection was issued for all of Donald's kids and his wife Melania.

Massler's bail was set at $10,000 -- as long as he sees a psychiatrist once a week.

TMZ has obtained the mug shot taken when Justin Bieber's manager turned himself in to police earlier this week over a Twitter-related incident.

As we first reported, Scooter Braun was wanted on two misdemeanor charges for allegedly refusing to listen to cops last year when they asked him to post a Tweet letting rampaging Bieber fans know that a mall concert had been canceled.

Justin is currently running an adorable little t-shirt protest to show his support for his manager.

Braun pleaded not guilty to both charges.

As we previously reported, Scooter turned himself in this morning over an incident at a mall last year -- in which he allegedly refused to post a Tweet informing crazed Bieberettes that a concert had been canceled.

Ben Roethlisberger's accuser may have dropped out of school, but her sorority is closing ranks. TMZ has learned the group's leaders issued sorority-wide marching orders ... including a mass Facebook takedown.

Sources at Georgia College & State University -- where the accuser was enrolled before the alleged incident -- tell us the accuser's sorority sisters have been ordered to take down each of their Facebook and Twitter accounts and refrain from wearing any clothing with the sorority letters until further notice.

We're told three members of the sorority's national office visited the campus sorority house to check in on the situation and may return later this week.

It seems Paris is an even bigger star now than in her 2006 heyday.

The Cone Zone posted the above photo on his Twitter page yesterday with the message, "This is how many people it took to write today's tweet: "Jumbo" shrimp? WTF!!"

... still funnier than Leno.

The former "American Idol" contestant is in Chile for the Viña del Mar International Song Festival. He bashed the experience last night on Twitter, saying, "Thanks 4 nothing Chile!...what an aweful experience!"

Less than an hour later, an 8.8 magnitude earthquake hit and Yamin began tweeting:

-- "Huge earthquake just now in Chile!!....I swear I thought this was the end of my life!!!!!"

-- "F**k!!!!!! I take it all back everybody!!....I just escaped w my life,from an 8.3 earthquake!!!...is everybody ok?...where was the epicener?"

-- "Complete and utter choas on the streets...no power...my heart is beatin outta my chest!....tsunami warnin...I am only a mile inland!"

Kevin Smith was thrown off a Southwest Airlines flight yesterday for being a "safety risk" -- a polite way of saying he was deemed too fat to fly.

Smith was flying from Oakland to Burbank and was, according to his own tweets, already seated and ready to go when a Southwest attendant named Suzanne "told me Captain Leysath deemed me a 'safety risk.'"

He flew into Oakland on a SW flight, and tweeted later (along with the photo on the right) that he eventually flew out on one as well.

Smith also received a $100 voucher for his trouble and a few apologetic tweets from SWA, but based on the number of four-letter words used on Smith's Twitter page ... we don't think the apology was accepted.

UPDATE: Southwest responded to Silent Bobgate on their blog.

UPDATE 2: The SW site seems to be down. Read the blog entry by clicking below.

Since Tila tweets her every moment, she provided her own play-by-play of the accident. Tila first said she fell off her chair and "slammed my head into the wall and heard the back of my skull crack. theres a dent in it now!"

Shortly thereafter, Tila recalled the tragic events of Natasha Richardson (but not her name) when she tweeted: "I should call the ambulance just in case? like that one actress that died cuz she hit her head &thought she was ok but died later..pray 4 me."

Tila's next entry: "Ambulance on the way to my house. I could have a brain concussion and die ina few hours."

Tila's agent provided the final tweet of the night, saying Tila suffered a concussion and wouldn't be able to tweet any further updates. Tila was released from the hospital and returned home last night.

Just one day after the real Dr. Murray appeared in court to face an involuntary manslaughter charge in the death of Michael Jackson, a person using a Twitter account under the name DrConradMurray left the following message:

"Please consider that I too am a father, do not judge or condemn me until you have walked in my shoes. Please pray for my family"

But it's all a hoax: TMZ spoke to a rep for Dr. Murray's lawyer who told us, "It is 100 percent fake. He doesn't even have a smart phone."

John Mayer is apologizing for using the N-Word in that explosively controversial Playboy interview in which he compared his penis to a white supremacist.

During the interview, Mayer stated that "black people" love him -- and then he brought up the topic of a "hood pass."

While explaining the meaning of a hood pass, Mayer said, "It's sort of a contradiction in terms, because if you really had a hood pass, you could call it a n*gger pass."

But moments ago, Mayer issued an apology, via Twitter, saying "I am sorry that I used the word. And it's such a shame that I did because the point I was trying to make was in the exact opposite spirit of the word itself."

Snooki apparently regrets flipping the bird at the city of Philadelphia this morning -- and is now apologizing for her fowl finger.

The "Jersey Shore" star just apologized on her Twitter, posting "Sorry philly for the reaction this morning I got caught up in the moment and wing bowl is nuts!"
