Jay Leno will get his one-hour show back, and it will be called "The Tonight Show".... sources tell TMZ.

We're told NBC honchos still have to sit down with Jay's rep and put the finishing touches on a new deal, but NBC has signed off on the plan if Conan O'Brien leaves ... and Conan has made it clear that he's leaving the network, and not on good terms.

O'Brien took several cheap shots at Leno in his blistering letter, denigrating Leno's show as a "comedy program."

Sources tell TMZ Jay and Conan have not spoken with each other since NBC announced the switch.

It's looking increasingly like Conan may be making a deal with Fox for a late night show from 11:00 PM to midnight.

According to court documents filed last week in L.A. County Superior Court, the current DJ Chris Kilmore (left) claims the old DJ Gavin Koppel (right) threatened to kill him last month -- over an incident that went down in 2003.

Kilmore -- who replaced Koppel in 1998 -- had previously obtained a restraining order against Koppel in 2003 after Koppel allegedly spit in his face.

But now, a judge has granted a new restraining order against Koppel, after Kilmore alleged that the old DJ approached him at a store on December 28, 2009 and said, "You will get killed if you don't lift that order ... people get killed in the street for that."

Kilmore also claims Koppel, "asked me to fight him right there and raised his fists to me."

The certificate lists Casey's death as "deferred."

She's listed as an "artist" and a "HS Graduate" -- Her date of death is"1/4/2010 FND." As we first reported, Casey's body was found on January 4 ... it's unknown when she actually passed away, but we're told her body was undiscovered for several days.

Casey's cause of death is still unknown, but our sources say her frail medical condition -- including diabetes -- may have caused her death.

Turns out Vanessa Lopez -- who is reportedly filing suit today against Shaq -- went to police after a bitter breakup with Redick back in 2007.

filed in Lake Mary, Florida, Lopez claimed she was being harassed by Redick's brother, David. According to the report, one of the alleged incidents occurred at the infamous Blue Martini bar in Orlando -- where Tiger Woods used to hang out.

According to the police report, while the cops were at Lopez's house taking a report, David called her and said he would leave her alone "when she leaves J.J. alone."

As TMZ first reported, Lopez also had problems with two other NBA players -- Delonte West and Kenyon Martin.

Lopez is expected to appear at a news conference with Gloria Allred later today to address the Shaq lawsuit.

We've obtained photos of the 5 bedroom, 5 bath, 6,000 sq. ft. mansion where Elin Nordegren has been living with her two kids. It's near the gated community where she lived with Tiger in Windermere, Florida.

We're told she's been living in the house -- valued at a cool $2 mil -- since mid-December.

Casey Johnson's funeral was held today on the East Coast, family sources tell TMZ.

We broke the story that the Johnson & Johnson heiress died ... possibly late last month, though her body was found on January 4.

Sources say it's increasingly looking like Johnson's frail medical condition -- which included diabetes -- may have caused her death.

We found out Octomom fell behind on her membership fees at least three times at 24 Hour Fitness. Looks like the gym has a 3 strikes rule, because our sources say Octomom's membership was yanked January 4.

As for what led up to the termination ... Octo apparently used at least two credit or debit cards that were declined.

Suggestion -- if Octo needs a workout, she can lift her 14 kids.

As TMZ first reported, Lohan's driver was a "person of interest" in an assault with a deadly weapon investigation after she allegedly clipped a pap with her car while trying to drive Lindsay through an alley this weekend.

But law enforcement sources tell us authorities watched footage of the incident and have decided the collision doesn't meet the standards of an assault with a deadly weapon. Frankly, we watched the footage and the "alleged assault" looked like a bunch of nothing.

The guy who punched Snooki in the face on "Jersey Shore" won't even be punching the clock anymore -- TMZ has learned he's being fired from his job as a gym teacher at a high school in New York.

NY City Department of Education says they are drafting Brad Ferro's termination letter right now -- and once he gets it, he'll have 30 days to pack up his stuff and split from North Queens Community High School.

Dude had already been banished to a teacher reassignment center in the wake of the punch -- but now, because he was found guilty of simple assault for the Snooki attack -- school officials tell us, "the termination process is underway."

Talk about a black eye on your permanent record ...

We've learned Cowell and Fox had been negotiating the terms of the move for weeks. We're told the deal was basically done and the plan was for Cowell to make the announcement at the Television Critics Association.

But there was an unexpected snag yesterday morning. As Simon drove to the TCA in Pasadena, final negotiations hit a wall. Lawyers for both sides had a serious disagreement over one of the terms. As Simon was pulling up, he was on the phone and on the verge of aborting the announcement and driving away -- the ultimate game of brinkmanship.

Someone blinked ... because lawyers came to terms and Simon rolled out of his Rolls and into TV history.

UPDATE: Simon was just on Ryan Seacrest's morning show and confirmed they "were driving down to do the press conference and we didn't have an agreement."

The Washington Wizards have told locker room pistolero Gilbert Arenas they believe he is in violation of his contract and they have the right to void the $111 million deal ... sources tell TMZ.

We're told a team official was trading text messages with Arenas after the locker room incident. Sources tell TMZ ... in one of the messages, the official told Arenas the team felt Agent Zero violated the clause in his contract prohibiting him from engaging in conduct detrimental to the team or the NBA ... and they could have the contract voided as a result.

Most NBA contracts contain morality clauses -- but it's difficult to void an NBA contract on those grounds. The Indiana Pacers didn't void Ron Artest's contract after "The Malice at the Palace" in 2004.

Nevertheless, there are strong indications the Wizards want out of the Arenas deal. As one law enforcement source put it, the team has been overly cooperative in the police investigation that targets Arenas.

On January 5th -- one day after TMZ broke the story that title to the 8,347 square foot Tarzana, Ca mansion was held in Lamar's name alone -- Odom filed a new legal document to make the mansion JOINT property.

According to the prenup, Lamar has the right to keep the home in his name alone -- so the move is a pretty big sign of how Odom views his marriage.

And they said it wouldn't last...

Outside JFK airport yesterday, we talked to the failed VP candidate -- who just inked a multi-year deal with the news network as a correspondent -- where she posed her first question as a hard-hitting journalist ... "What would America do without Fox News?"

One answer: We'd see a whole lot less of Sarah Palin.

Now discuss amongst yourselves.

The lovely ladies may have gotten away from the Big Brother house, but not the cameras.

Paula Abdul has had discussions with Simon Cowell about being a judge on the U.S. version of "The X Factor"... sources tell TMZ.

The irony is stunning -- Simon, the lynchpin of "American Idol," abandoning ship and teaming up with the woman who was unceremoniously dumped from "A.I."

Our sources would not say how far along the discussions have gone between Simon and Paula ... but there were talks as recently as late last week.

Don't judge.
