Glee

Naya Rivera and Lea Michele were at the center of a near mutiny on the set of "Glee" that ended with one of them storming out in anger -- but who left ... depends on who you ask.

Sources close to Naya tell TMZ most of the cast and crew were annoyed on Tuesday by Lea's diva antics -- like making everyone else wait to shoot a scene ... while she stepped away to deal with personal matters.

We're told tensions finally got so bad Naya "had the stones" to go to producers and let them know -- on behalf of everyone -- that Lea was pissing off people.

Our Naya sources say when Lea returned to resume shooting she got wind of Naya's chat with producers -- and left the set in a huff.

Now our Lea sources had a different take -- telling us Lea was totally unaware of any complaints about her ... and Lea and Naya weren't even shooting scenes together. They also say it was Naya who got tossed off the set.

We got several tips claiming Naya was fired -- but Naya sources say that's just not true.

Drama developing ...

Big Sean broke off his engagement to Naya Rivera because he was scared off by her violent fits of anger and jealousy.

As we reported, the rapper announced yesterday he and Naya had called off their wedding -- we're told B.S. made the decision weeks ago after realizing his fiancee was way too controlling.

Our sources say Naya demanded to know where he was at all times and would threaten him by saying things like, "If you don't listen to what I say, I'll ruin your career."

We're told she was suspicious whenever Sean was with other women and would work herself up into jealous rages ... once breaking an expensive lamp during a rampage in his home.

We're also told Big Sean and Naya went to couples counseling -- which apparently worked because Sean realized how much he HATED being a couple ... and decided to get the hell out.

We've reached out to Naya's camp ... but so far, no response.

The split between Big Sean and Naya Rivera is already turning nasty -- with Naya accusing the rapper of stealing expensive jewelry from her house.

Sean's rep announced today that Sean had called off their engagement and wedding ... but insisted "recent rumors and accusations" had nothing to do with the breakup -- a reference to reports claiming he cheated.

Sources close to the couple tell TMZ ... the cheating rumors are 100% false and that Sean actually made the decision to call off the wedding weeks ago. We're told he thought Naya was too controlling and too jealous of the women he worked with and met on tour.

The "Glee" star took to Twitter today to accuse BS of thievery ... claiming he stole a pricey Rolex watch from her. But sources tell us the watch was Sean's in the first place -- he bought it for himself when he became successful. We're told Sean gave it to Naya to wear ... but it was never hers to keep.

Cory Monteith was shooting heroin and downing champagne in his hotel room on the night of his death ... this according to the final coroner's report obtained by TMZ.

The "Glee" star was discovered alone in his hotel room in Vancouver, Canada on July 13 shortly after noon.

When responders arrived to the scene, they discovered a "spoon with drug residue and a used hypodermic needle."

They also found 2 empty champagne bottles and glasses.

The coroner lists Monteith's official cause of death as "mixed drug toxicity, involving intravenous heroin use combined with the ingestion of alcohol."

The report also notes that Cory "had a history of illicit drug use with intermittent periods of rehabilitation and of abstinence from drugs."

The coroner suggests that Cory's tolerance for substance abuse may have been lower than usual because he had stopped using since a rehab stint in April.

Monteith was 31.

When it comes to Jane Lynch and marriage ... she wants you to know the doctor is NOT in -- and yes, you can take that a couple of different ways.

We caught up with Jane outside her usual spot ... Kings Road Cafe, where she was chilling with Matt Sorum -- the Velvet Revolver drummer and soon-to-be groom -- and we've never seen her laugh this hard.

Jane absolutely busted up when we asked if she was giving Matt tips on achieving marital bliss. Her response is hysterical ... and maybe a little sad.

TMZ broke the story ... the "Glee" star is divorcing her wife, Dr. Lara Embry -- though she seems totally chill with the sitch in this clip.

Jane Lynch just delivered a powerful tribute at the Emmys for her "Glee" costar Cory Monteith ... that definitely won't make Jack Klugman's son feel any better.

Jane pulled no punches during the speech ... reminding the audience Cory "wasn't perfect" -- and referred to his death as a reminder of the dangers of addiction.

Jane Lynch was shockingly candid today when we asked her how she felt about her "Glee" co-star Cory Monteith getting a special tribute while TV icon Jack Klugman is getting the bum's rush.

Jane was locked and loaded when we approached her ... and had clearly thought it through before she left home for Kings Road Cafe.

Emmy winner Peter MacNicol is not buying what Jack Klugman's angry son is selling because Peter thinks the tribute to Cory Monteith could actually save lives.

MacNicol -- who won an Emmy for "Ally McBeal" and also starred in classics like "Ghostbusters II" and "Sophie's Choice" -- tells TMZ tonight's tribute to Cory will create enormous drug awareness and possibly reach thousands of teens on a path of destruction.

Peter doesn't think it matters that Cory died without a single Emmy. He says, "If we are going to get into a merit system based on longevity then we are in trouble."

Tell that to Adam Klugman -- who is furious that his 3-time Emmy winning deceased father is barely getting a mention at tonight's ceremony.

Cory Monteith's mom thinks Jack Klugman's son has it all wrong -- because Cory could have been the next Jack Klugman had he lived.

Ann McGregor thinks Adam Klugman is being unfair, telling TMZ her son is absolutely worthy of getting a special in memoriam honor at tonight's Emmy Awards ... even though Jack isn't getting one.

Ann tells us she believes you cannot judge worthiness by a person's age because her son was on a path of greatness -- not only with his acting and singing abilities ... but with the charitable work he did.

Ann tells us, "If he had lived 30 more years he would have accomplished much more."

Ann believes Adam Klugman is misdirected ... and thinks its coming from a place of a son who loves and misses his father.

Jack Klugman -- who has won 3 Emmys and starred in TV classics -- "The Odd Couple" and "Quincy M.E." -- has been overlooked and disrespected for special mention during tonight's ceremony. Instead ... Cory Monteith gets the honor. Jack's son thinks it's ridiculous and disrespectful, and he's right.

The Emmys are honoring 5 TV types who died in the last year -- 4 of whom have earned their stripes ... Jonathan Winters, Jean Stapleton, James Gandolfini, Gary David Goldberg -- and then there's Cory.

BTW ... Larry Hagman was also overlooked.

It's clear marriage wasn't right for Jane Lynch -- at least not now -- 'cause the "Glee" star tells TMZ she's really diggin' the single life at the moment.

The always friendly Lynch was out in Bev Hills the other day when we asked her if she's ready to meet some new ladies, now that a couple of months have passed since she and wife Lara Embry split up.

But Lynch says she's not sure she wants to jump back into a relationship -- telling us, "I kinda like being single."

Makes sense, considering Lynch's divorce recently turned nasty -- with Embry trying to nail Jane to the wall with more than $93k per month in spousal support.

Jane Lynch scoffs at the notion that gay people have hastily jumped into marriage ... this in the wake of what has become a contentious divorce between her and wife Lara Embry.

TMZ broke the story ... Embry is now trying to nail Jane to the wall with spousal support ... she wants more than $93k a month.

Embry says she wants Jane to support her in the lifestyle to which she has become accustomed during their 3 years of marriage. Shockingly, Jane isn't blanching at that.

Jane Lynch and Dr. Lara Embry's "amicable" divorce just turned "unfriendly" ... because Embry is making a full-court press for Jane's bank accounts -- to the tune of $93,809 a month in spousal support!

In new legal docs, obtained by TMZ, Embry says for the last 3 years, Jane's average monthly income has been $234,688. Embry also says when she married Lynch, Jane told her she had $400,000 in her savings and 401K combined, and owned her home.

Embry says of her "Glee" wife, "Her income, investments and assets increased dramatically with her newfound acting success."

Embry -- who says she wants Jane to support her in the lifestyle to which she gladly became accustomed -- says during their marriage Jane paid for everything, including lavish vacations.

Embry says she and Jane typically racked up $40k a month on their credit cards.

According to Embry's docs, she currently earns pennies, but still spends in the neighborhood of $40,900 per month -- including an average of $6,500 on clothes, $12,000 on entertainment/gifts/vacation, and $4,500 on eating out (hehe).

Sources tell us ... Jane is already providing Embry with support. In fact, Embry and her daughter are living in the house Jane bought and Jane temporarily moved elsewhere. But the house is a big sticking point. Embry says they sunk $3 mil into the house for renovations and from the docs it seems she either wants the house or a 50% cut.

Sources tell us the couple did not have a prenup, which means assets acquired during the marriage will probably be split 50/50.

Jane filed to end her three-year marriage to Lara in July, citing "irreconcilable differences." The two first met in 2009 at a fundraiser in San Francisco. They were married a year later in Massachusetts.

Jane said recently the financial negotiations have been friendly, adding, "It's just money." Right.

Lea Michele had her first public outing after the tragic death of BF Cory Monteith ... to celebrate the birth of a friend's baby.

The "Glee" star has been grieving privately since news broke that Monteith had been found dead last month in a Vancouver hotel ... after OD'ing on heroin.

The "Glee" cast is finally beginning to heal after Cory Monteith's death -- so says the late actor's co-star Jane Lynch ... who tells TMZ, she found new comfort during today's special memorial organized by Monteith's gf Lea Michele.

Lynch was out in L.A. when we asked about the memorial -- co-organized by "Glee" creator Ryan Murphy -- where the cast and crew gathered to say their final goodbyes to the late actor, sharing memories and music. Lynch gave a glowing review.

As we reported, 31-year-old Monteith died from a heroin overdose at a Vancouver hotel on July 13.

Jane Lynch and her estranged wife Lara Embry are BACK TOGETHER -- just kidding ... it's just one of Jane's close friends ... who happens to look exactly like Lara.

Jane hit the streets of West Hollywood Monday with their dogs -- and everyone on the planet thought Jane and Lara were patching things up, but it's just not so.

The other woman in the photo is actually Jane's longtime friend Laura Coyle ... but, yeah ... she does look A LOT like Lara.

As we reported, Jane revealed last month that she and her estranged wife were calling off their 3-year marriage.
