Demi Lovato went on a Twitter rampage last night against her former bosses at Disney over an eating disorder joke on one of their shows -- and guess what??? Disney folded and promised to pull the joke from the show.

Lovato, who left the Disney show "Sonny With a Chance" to battle her own problems with food, took offense to a line from the show,"Shake It Up" -- "I could just eat you up, well if I ate."

Demi sent out a flurry of tweets, one of which read, "I find it really funny how a company can lose one of their actress' from the pressures of an EATING DISORDER and yet still make joke about that very disease..... #nice."

Word got back to the Mouse House and they responded to Demi in a matter of hours from a PR Twitter account: "We hear you & are pulling both episodes as quickly as possible & reevaluating them ... It’s NEVER our intention to make light of eating disorders!"

Kiefer Sutherland just scared the living crap out of a perfectly innocent Christmas tree ... pretending to form tackle the fur ... in a new holiday card intended to spoof his famous tree dive of '06.

If you recall, Kiefer ferociously murdered a suspicious-looking Xmas plant in a London hotel during the filming of the documentary "I Trust You to Kill Me" ... possibly because he may have been drunk at the time.

Now, Sutherland has mocked the incident ... posting the greeting card to his Twitter page.

Pretty funny ... but nothing beats the real thing.

Orthodox Jew rapper Matisyahu took a razor blade to the face this week ... and shaved off his trademark beard ... or so it seems.

Matisyahu just posted the shorn pics of himself on his Twitter page ... along with the message, "At the break of day I look for you at sunrise ... When the tide comes in I lose my disguise."

We're reaching out to Matisyahu for comment -- we'll fill you in on the beard drama as it unfolds.

10:38 AM PST -- Matisyahu has posted a blog, explaining his decision to chop his face warmer ... in which he writes, "No more Chassidic reggae superstar."

He adds, "Sorry folks, all you get is me ... no alias. When I started becoming religious 10 years ago it was a very natural and organic process. It was my choice. My journey to discover my roots and explore Jewish spirituality—not through books but through real life."

"At a certain point I felt the need to submit to a higher level of religiosity…to move away from my intuition and to accept an ultimate truth. I felt that in order to become a good person I needed rules -- lots of them -- or else I would somehow fall apart. I am reclaiming myself. Trusting my goodness and my divine mission.

Get ready for an amazing year filled with music of rebirth. And for those concerned with my naked face, don’t worry…you haven’t seen the last of my facial hair."

Homeless people in Indiana are feeling the wrath of Charlie Sheen's former goddess Bree Olson -- who's BEGGING her community to stop giving money to beggars.

Olson ignited a firestorm on Twitter earlier today when she posted a photo of a beggar -- and wrote, "STOP giving then money Fort Wayne! The more you give them money this place is gonna start looking like Skid Row."

She added, "Fort Wayne has PLENTY of room in the shelters and almost every church has food shelter and placement. No excuse for him or the others here."

Olson -- a former porn star -- was bombarded with insults from people who don't see things her way. One person wrote, "Some people are more comfortable asking for help than sucking d*** for money."

Still, we gotta ask ...

Ashton Kutcher doesn't trust himself with his own thoughts ... claiming his ignorant Twitter defense of Joe Paterno has made him realize that he isn't qualified to speak to 8 million people.

Kutcher just posted a long-winded message on his blog -- explaining that he has decided to turn over control of his Twitter account to his management team -- which will now filter Ashton's stream of uninformed thoughts before they are unleashed on the masses.

Kutcher writes, "Up until today I have posted virtually everyone of my tweets on my own, but clearly the platform has become to big to be managed by a single individual."

He continued, "While I will continue to express myself through @Aplusk I'm going to turn the management of the feed over to my team at Katalyst Media to ensure the quality of it's content."

Snoop Dogg, a famously huge football fan, tweeted his thoughts today on the passing of Al Davis.

Not a good month for Mark Ballas -- two weeks after the "Dancing with the Stars" pro lost his hot girlfriend Pia Toscano ... some heartless burglar busted his car window and jacked his guitar.

Ballas posted the bad-luck news this weekend on his Twitter -- writing, "My car just got broke into and my first Martin guitar was taken..."

To make matters worse, Ballas says his super-expensive Breitling watch was stolen earlier last week.

On his way out of "DWTS" practice, Ballas told photogs he'll pay good money to get Marty back.

Russell Brand has managed to find another country that doesn't want him -- he's been denied entry to Canada.

Brand first tweeted, possibly while still flying, "HELP! I'm gonna be late for Casino Rama show unless someone can force Canadian customs officials to let us land in Orillia!"

He then tweeted a few hours later that his concert tonight was cancelled because he couldn't get in the country (see above).

Brand was deported from Japan back in May while trying to visit with his wife, Katy Perry.

DJ Qualls posted dozens of messages to his Twitter page early this morning, detailing what he says was an unwarranted beat down he took from a Vancouver police officer.

Qualls -- best known for his roles in "Road Trip" and "Memphis Beat" -- says he witness a fight in the street and tried to ID one of the attackers to a police officer, but that officer immediately turned on him and threatened to arrest him. He claims the officer tackled him to the ground, busted his face, handcuffed him and "Taunted me for 1/2hr b4 the ambulance came. I was held, no calls, no attorney. AND I had to pay an $800 ER bill. Free healthcare, Canada?"

Qualls, who ID'd the officer by name, said he plans on taking the matter up with internal affairs and wants to be reimbursed for his hospital bills.

Calls to Vancouver PD were not returned.

50 Cent is telling friends ... there's a reason he was laughing his ass off at Ray J and Fabolous -- their little Twitter feud was like a fight between two school girls.

We posted video of the Vegas "brawl," which shows Fiddy standing in the background grinning as Ray J and Fabolous went at it.

Sources close to Fiddy tell TMZ, contrary to what some witnesses are saying, the rapper didn't egg Ray J and Fabolous on. He just couldn't believe they were seriously arguing over Twitter.

Days after the fight, Ray J was still taking himself way too seriously in Vegas -- telling us, "I'm not that proud of nothing that happened."

Fact is ... rapper feuds over Twitter kinda ruins the whole street cred thing.

So we ask ...

Ray J didn't take too kindly to Fabolous talking smack about him on Twitter, so when he saw him out in Las Vegas this weekend ... he clocked him!

Kim K's sex tape partner re-told the tale on Power 105.1 this morning, explaining, "When I seen him, I was with Floyd [Mayweather] and 50 [Cent] and he tried to say, 'Don't touch me.' And I touched that n***a!"

Ray J says he got kicked out of the Palms and detained by police, but according to cops in Vegas ... he was not arrested.

Rachel Uchitel visited the memorial at Ground Zero this morning to pay her respects to those who lost their lives on September 11 -- including her fiancé at the time, James Andrew O'Grady.

Uchitel is currently embroiled in a spat with Page Six Magazine, which ran an article that quoted her as saying, "I believe Andy was meant to die because he was too good."

Rapper Kreayshawn -- the 21-year-old behind that "Gucci Gucci" song -- claims someone hacked her Twitter account and leaked nude pics that she posed for when she was underage.

Kreayshawn went online this morning and explained the situation -- saying, "My twitter got hacked today by some anti-hollywood extremists."

"They sent out wack ass tweets and promoted their odd message of anti-jew stuff and deleted my twitter.. Oh and they leaked out private photos of me while I was underage."

Kristin Cavallari has one less thing to worry about when she hits up the Marine Corps Ball with Jonathan Burkett -- his mother is on board.

As TMZ first reported, Cavallari accepted Burkett's Twitter invitation to the event in San Diego in November. Burkett's mom tells TMZ she's not sure why her son chose KC, but she thinks it was a "cool" and "gutsy" thing to do.

Who needs a Bear ... when you can have a U.S. MARINE?!?

TMZ has learned Kristin Cavallari has accepted an invitation to attend a Marine Corps Ball in San Diego in November after a Devil Dog named Jonathan Burkett extended an invitation via Twitter yesterday.

The message read, "Wanted to know if you want to go the the Marine Corps Ball with me in San Diego?! Would make a video but still deployed!"

Cavallari promptly replied,"Would love to! When is it?" ... and now TMZ has learned her people are working out the details to make it happen.

"New Edition" singer Johnny Gill has buried the hatchet with the woman who sued him for calling her "f**king nuts" and "deranged" on Twitter -- and now the two are actually working together again.

TMZ has learned ... Ira DeWitt -- CEO of Notifi records -- has agreed to drop her lawsuit in which she claimed Gill damaged her reputation when he tweeted that she was responsible for leaking an unfinished single from his upcoming album. He also called her some unflattering names.

DeWitt -- who's producing Gill's album -- tells us .. "I'm very happy to put this dispute behind us and I'm confident that [Gill's] loyal fans will be thrilled with the final product."

Gill -- who agreed to go back on Twitter and express regret over the situation -- says, "I'm elated to continue this journey that I've started with Ira and Notifi Records."
