Exclusive Details

Chris Brown has just entered a rehab facility for anger management issues ... presumably to deal with his temper problems and to blunt a possible prison sentence.

Sources tell TMZ ... Brown's attorney, Mark Geragos, just dropped him off at a facility in Malibu. The move doesn't come a day too soon.

We've learned the L.A. County probation department is going full bore in its investigation to determine if Brown violated his probation in the Rihanna case by getting arrested in D.C. over the weekend ... after allegedly punching a guy in the nose.

Sources tell TMZ, Brown flew to L.A. after getting released from the D.C. jail and met with L.A. County Probation Department officials today.

We're told it's likely the Probation Department will determine that Brown violated his probation, and a judge could sentence him to as much as 4 years in prison.

Along with Geragos, we're told his mom and GF Karrueche accompanied Chris to the facility. Geragos and the others went to dinner after dropping Chris off. We asked him about Chris, but he wanted to talk about his meal (see video below).

The rehab move could show a measure of good faith and contrition.

Mrs. Krabappel WILL be written off "The Simpsons" in the wake of the death of the actress who voiced the character ... but it's not going to happen for a while, TMZ has learned.

TMZ spoke with "Simpsons" E.P. Al Jean who tells us ... no one could possibly fill Marcia Wallace's shoes as the voice of Ned Flanders' 2nd wife -- so they're not even going to try.

Al says producers do plan to write Edna off the show -- but there's no rush, because the series is produced so far in advance, Marcia had a year's worth of episodes recorded when she passed away.

TMZ broke the story ... Edna is NOT the mystery character that producers had planned to kill off the show this coming season. Al wouldn't say how Edna will leave Springfield.

As for Marcia, we're told the legendary comedy actress will be laid to rest in the next few days in a private ceremony.

Chris Brown just got cut a big break ... the assault charge has just been reduced from a FELONY to a MISDEMEANOR ... and Chris pled not guilty. Chris has just been released without bail. He's also required to stay 100 yards away from the victim.

Chris had been ordered to take a drug test, but the judge just vacated that order. It's standard in such cases to order a drug test, but that has been cancelled.

The bodyguard's charge was also reduced to a misdemeanor.

TMZ broke the story ... Brown was arrested for felony assault early Sunday morning in Washington D.C. after allegedly attacking a man outside a hotel and breaking his nose.

Brown allegedly got into an argument with a man, said "I'm not down with that gay s**t, I'm into boxing," and then punched him in the nose.

Law enforcement sources tell TMZ ... the fight started when the man and his friend photobombed Chris, who was posing for a picture with two girls.

Sources close to Chris insist the fight wasn't over a photo -- they say the alleged victim tried to force his way onto Chris' tour bus, and Chris was merely trying to stop a trespass.

Brown has been in custody since the incident.

3:45 PM PDT: TMZ has just obtained witness statements, some of which conflict. Chris DENIES punching the victim. According to Chris' statement, he claims he was on his tour bus when the victim tried getting on and his bodyguard "handled it."

The victim says he was trying to get a pic with Chris and Brown allegedly said, "I ain't down wit that gay s**t." The victim told cops he responded by saying, "Why you hoing?" Chris then said, "I feel like boxing." The victim says Chris then threw the punch and the victim says he then squared off with Chris and then the bodyguard also hit the victim in the face.

According to the victim, after the bodyguard punched him, Chris got BEHIND the bodyguard and screamed, "Yeah, walk away."

The police say the victim was treated for a fractured nasal bone.

Jason Aldean's tour bus ran over and killed a man early this morning in Indiana ... TMZ has learned.

The accident occurred around 1:30 AM when Aldean's bus ran into a man who walked into the middle of the road ... law enforcement officials tell us.

Cops say Aldean was on the bus when the crash occurred.

We're told the bus driver was not at fault. In fact, cops tell us the driver did everything he could in an effort to minimize impact.

Sheriff Michael Morris tells us the victim was often seen walking around town ... but it's unclear why he walked into traffic.

Quincy Jones says he's been double-crossed by Sony and Michael Jackson Productions (aka MJJ) ... claiming the 2 companies intentionally aced him out of his cut of Michael's music.

Jones has sued MJJ Productions and Sony ... claiming he owns a big chunk of "Off the Wall," "Thriller" and "Bad" because he produced all of them. Jones claims Sony and MJJ concocted a scheme to edit and remix the original songs and put them into new ventures such as the "This Is It" movie, the Cirque du Soleil stage show and the 25th Anniversary of the "Bad" album and then deny him royalties.

The allegations are even worse. Jones says MJJ and Sony created a shell game and diverted millions of bucks away from what is rightfully his.

Howard Weitzman, lawyer for the Michael Jackson Estate, tells TMZ, "The Estate of Michael Jackson was saddened to learn that Quincy Jones has filed a lawsuit seeking money from Michael's Estate. To the best of our knowledge, Mr. Jones has been appropriately compensated over approximately 35 years for his work with Michael."

Weird Al Yankovic is the danger ... HE IS THE ONE WHO KNOCKS ... at least on his birthday.

The singer and self-professed "Breaking Bad" fan turned 54 today, and marked the occasion just like Walter White does on the show -- arranging his bacon in the shape of his age -- but Al tells us, there's something special about his bacon ... it's veggie.

Which leads us to our FUN FACT OF THE DAY: Weird Al is a vegetarian.

And this is cute, he says his wife prepared the breakfast surprise for him because she knows he's a big fan. Happy birthday!!!

As for his new album -- which Al first told us about last month -- he says he's still working hard on it, and it WILL be released ... he's just not sure when.

The engagement comes 4 months after Kim and Kanye's daughter North was born -- and 18 months after they went public as a couple.

Monday was Kim's 33rd birthday. This will be her third shot at "til death do us part," and Kanye's first.

BTW -- In case you're interested, it costs $35k to rent out the field. We're guessing he can afford it.

Jenna Jameson was a MESS during a live TV interview this morning ... slurring and stumbling as if she was wasted on-air ... and it was so bad, sources tell TMZ that producers cut her segment short.

The 39-year-old porn legend appeared on "Good Day New York" -- promoting her first novel, "Sugar" -- and we're told she was supposed to stay for two complete segments.

But after the first couple of minutes, it was clear Jenna was out of it (at the very least) ... and producers made the decision to cut off JJ before the second segment.

Jenna has struggled with substance abuse in the past .. she pled guilty to DUI last year after crashing her car into a light pole in Orange County, CA. Officials say she had two types of prescription drugs in her system at the time of the incident.

Jenna's ex Tito Ortiz has also said Jenna is hooked on Oxycontin -- but Jenna has denied those allegations.

The FBI, the Boston PD, the Dept. of Homeland Security ... just about every law enforcement group in the land will be patrolling the Boston area in force during the World Series in an effort to thwart a possible terrorist attack, TMZ has learned.

In the wake of the Boston Marathon bombing back in April, the city is taking every possible measure to make sure people are safe when the Series comes to Beantown on Wednesday.

TMZ spoke with multiple law enforcement agencies ... who told us the Boston PD will be in charge of coordinating the plan to keep the area safe.

The police presence will be huge -- and in your face -- with uniformed and undercover officers, bomb-sniffing dogs, snipers and other counterterrorism measures in place.

Still, cops tell us ... as usual, they count on the people to provide tips if they see anything suspicious. See something, say something.

A shooting at Drai's nightclub in Las Vegas this morning has left at least 1 person dead and 2 others injured ... TMZ has learned.

Here's what went down ... witnesses tell TMZ a person, who appeared to be a white male, was loitering in the cashier area of the famous after-hours club around 5:45 AM.

When the man was approached by a club employee and asked to move, the suspect pulled out a gun and started yelling back at the staff.

One witness tells us someone in the area (not a member of the security team) tried to apprehend the suspect ... and that's when shots began to ring out.

We're told at least one person died from a gunshot and at least 2 others were injured.

The man was eventually taken into custody.

Drai's has been a staple in Vegas for years -- and has been popular with huge stars like Paris Hilton and Nick Cannon.

Timbaland celebrated his pending divorce last night in Paris -- with Jay Z, Lenny Kravitz ... and 30 ACE OF SPADES BOTTLES!!

The three rolled into Club 79 after Hova's Bercy Arena concert ... and an employee tell us the bottles were worth around $26k -- but they were all comped.

We're told Timbaland enjoyed a "guys night out" while taking pics with fans ... keeping things pretty mellow with the ladies, despite his new status.

TMZ broke the story ... Timbaland's wife filed for divorce this week and asked for the rapper to pay child support on two kids -- one he fathered, one he didn't.

So we started digging, to find out what triggered the explosion of anger. It seems Colin and the mom were bent out of shape because they were left in the dark about her possible pregnancy. They learned of it after reports surfaced yesterday.

Family sources tell us ... Kendra's mom called her daughter and apparently the conversation didn't go well, because it ended with a death wish.

Colin then stuck up for his mother and went nuts on Kendra.

NEWS FLASH: Pope Francis is a badass who owns not one, but TWO Harley-Davidson motorcycles.

BIGGER NEWS FLASH: He's auctioning them off for charity.

To get you up to speed, the Holy Father was gifted the two bikes by Harley-Davidson during a biker rally in Rome this summer, when 35,000 Harley enthusiasts rode into town to celebrate the 110th anniversary of the motorcycle company.

Roughly 800 of the riders went to the Vatican for a special blessing from the Pope, and during the event, Pope Frank was gifted two new hogs -- a 2013 Heritage Softail Classic (valued at $20,799) and a 2013 Dyna Super Glide Custom ($16,000).

Now Pope Francis has announced he's auctioning off the first bike to benefit a local homeless shelter. The second bike will also be auctioned off, but a charity hasn't been chosen for that one yet.

As for when the first auction takes place, that hasn't been announced yet either.

Amen.

Ricky Schroder has such fears his daughter's Malibu school causes cancer ... he's yanked her out, and we're told other high-profile parents have similar concerns.

Ricky tells TMZ ... the facts are scary -- 3 teachers at Malibu Middle School have been diagnosed with thyroid cancer in the last 6 months. Seven other teachers have experienced severe migraines and others say they have skin rashes, hair loss and other ailments.

Ricky says the buzz around the school is that soil around the school is contaminated with PCBs, lead and pesticides. Teachers also think the classrooms might be contaminated with mold.

Parents are now demanding tests for various contaminants, including radioactivity, asbestos and Ricky tells us ... he's physically removed his daughter from the school "as an abundance of caution" ... until it's determined it's safe for her to return. Until then, she's taking classes at home via independent study ... and about 25% of the students in her class are doing the same thing.

As for Ricky ... he says until he knows it's safe for his daughter to return to classes, she'll be homeschooled.

School officials are conducting more testing this week. According to a statement, preliminary tests showed "no unusual findings" for mold contamination ... and any mold found so far should not pose a health problem.

Adrian Peterson's baby count is now at 5 ... 'cause a 4th woman has surfaced who has a child with the NFL star, TMZ has learned.

This time, the baby mama is Erica Syion -- a former dancer who worked at a gentlemen's club in Dallas, TX. Erica and Adrian have a 4-year-old son together.

Sources connected to the situation tell us ... the two have a financial arrangement, in which Adrian gives Erica money to pay for the kid's schooling, as well as living expenses.

We're told the two met in Houston back in 2007 ... but their relationship has deteriorated in the past few years.

Sources tell us Adrian IS involved in the child's life -- but Erica is the primary parent, with Adrian visiting when he can.

In total, Adrian has fathered (at least) 5 children: 2 kids he referenced in a 2009 documentary ... one was 4 at the time. He didn't mention the age of the other (it's likely he was referencing his son with Erica).

Since then ... he fathered Adrian Peterson Jr. (who's 2-years-old) and a 3-month-old daughter with a waitress in Minnesota. His other son, a 2-year-old, passed away last week.

It's possible his 8-year-old and AP Jr. have the same mom -- but so far, we haven't been able to confirm.

Lamar Odom is way beyond first impressions with the Lakers ... but, all the same, he got a fresh shave of his head for a meeting with the team on Monday ... TMZ has learned.

Lamar's barber in the Valley, a dude named Enzo, hooked up the troubled NBA star Monday morning -- and even gave LO his trademark star on the back of his head ... which he sported during past seasons with the Lakers.

Our sources tell us Lamar met with Laker execs Monday afternoon to discuss terms of a possible return. We're told things went well -- though nothing's been signed -- and that Lamar's first choice has always been to return to the Lakers.

It's pretty amazing ... a little more than a month ago Lamar was smoking crack and deep in the throes of drug addiction. But as we first reported, Odom has been adamant he can cut off his drug abuse without going to rehab.

It remains to be seen if an NBA team buys that (and we know Khloe Kardashian isn't) -- but as one source put it ... lately Lamar has sounded more like his old self.

On his Instagram, Lamar's barber wrote, "Wish em the best of luck in his meeting wit the Lakers today."
