New York Knicks player Raymond Felton committed ADULTERY during his marriage ... so says his estranged wife in divorce docs obtained by TMZ Sports.

Ariane Raymondo Felton -- the same woman who ratted Raymond out to the cops about his illegal firearm -- filed docs last month in a New York court seeking to end their 18-month marriage.

But in the docs, Ariane penciled in that she's divorcing Felton because of "adultery."

Ariane doesn't go into detail about the adultery allegations ... but in the docs, she does request the judge throw out their pre-nup. It seems she wants the prenup tossed out on the count of the alleged cheating, but she doesn't explain why.

Call it CSI: Tarzana ... Khloe Kardashian is demanding lie detector tests for EVERYONE who had access to the jewelry stolen from her home ... and she want fingerprints too.

We're told Khloe suspects the jewelry thief or thieves who pilfered $250K worth of items is someone with direct access ... house staff, assistants, filming crews, inspectors and movers.

As we reported ... the thief or thieves made off with watches, diamonds and gold chains that were left in the house, which was recently sold.

It's likely an inside job because there's no sign of a break-in and the house sits inside a gated estate and the house itself is also gated.

Liza Minnelli didn't like the joke Ellen DeGeneres cracked about her at the Oscars ... suggesting she was actually a drag queen.

Liza and a male companion hit up Craig's restaurant in West Hollywood Monday night ... and Liza made it clear -- Ellen's joke backfired big time.

Liza's note to Ellen: She should have stopped and acknowledged they were friends, but instead Ellen blew through to the next joke, so it sounded mean.

But Liza says she's sure Ellen was filled with the best of intentions.

It's better than Bigfoot or the Loch Ness monster -- it's Justin Bieber holding one of his fabled STYROFOAM cups on his way into an ATL nightclub ... a clear sign of lean ... and it's all on video.

TMZ has obtained security footage at Tongue & Groove -- showing Bieber entering the club Monday evening holding a tall, white styrofoam cup ... the telltale container for lean ... aka sizzurp.

It's the first time Bieber's been seen holding one of these cups -- and our sources say he had the cojones to continue partying with it inside.

As we reported, Bieber's drug use -- specifically lean and weed -- has spiraled out of control in Atlanta ... in fact, one source said he was constantly high ... drinking more lean, smoking more weed than ever.

We're told the singer has ordered his goons to make sure NO ONE sees him carrying the white cup ... which has resulted in multiple fights with photogs.

Sure, George Lopez got bombed and wound up passed out on the floor of a casino -- cause, y'know ... not too many other options when you suck down several dozen shots.

Liquor. It's complicated.

Taylor Swift just got a restraining order against a guy who believes he's married to the singer and who vowed to murder anyone who stands between them -- including Secretary of State John Kerry.

Swift filed legal docs -- obtained by TMZ -- in which she claims Timothy Sweet has dogged her since January, 2011.

Sweet has sent a torrent of emails, letters, and social media posts professing his love for her.

Among the messages:

-- "If anyone in Taylor Swift's family gets killed, it is not my fault."
-- "My wife, Taylor Swift (Sweet) and I live in Beverly Hills. I am in love with her. In conclusion, we treat each other with dignity and respect. I will carry a gun to protect her the rest of my life."
-- "Dearest Taylor, I'll kill any man who gets in the way of our marriage. Message to John Kerry, Secretary of State. Message from YOUR Presidential Candidate."

Swift says she's worried for her safety and the safety of her family.

A star high school running back -- who reportedly committed to the University of South Florida -- was arrested Sunday after allegedly pulling a gun on a police officer ... all thanks to a brave police dog.

The suspect -- 18-year-old Marquise Bryant -- was confronted by an officer in Fort Myers, FL for loitering around 2:30 AM.

During the incident, the cop says Bryant reached for his right front pocket -- even after the cop told him to put his hands up.

The cop says Bryant continued to go for the pocket ... and a fight broke out between the two -- with Bryant allegedly pulling out a gun at one point.

But the officer was able to click a button that released his police dog Bala from the cop car -- and Bala bit Bryant on his right thigh.

50 Cent raised the stakes in his beef with 3 rap heavyweights -- publicly insinuating Diddy, Rick Ross and former record exec Steve Stoute are gay together ... but he backed down minutes later.

The shots were fired Sunday -- Fiddy posted the 2 pics on Instagram, one showing a pink-shirted Stoute embracing a pink-shirted Diddy. The other shows Diddy and Rick Ross from an angle that makes it look like they're kissing.

Underneath, 50 wrote the caption, "I ain't saying nothing, but something ain't right. Lmao." He yanked the pics down a short time later.

The photos were the latest in 50's ongoing feuds with the rap titans -- Stoute recently appeared in a VH1 documentary about hip hop, in which he called 50 a has-been. 50's been feuding with Rick Ross and Diddy for years.

Rihanna was in a real hurry to dinner Friday night in Paris -- not only did she get a police escort to the restaurant ... her car nearly ran over a crowd of pedestrians in the process.

You can see it all in the video -- Rihanna's police escort breezes through a crosswalk ... and several pedestrians try to cross the street behind it ... but Rihanna's car cuts them off. It's a really close call.

Thankfully, Rihanna made it to dinner in one piece. (FYI, the restaurant's called Farnesina.)

Now shut up and drive.

Protecting Sir Paul McCartney is no laughing matter -- and last night his bodyguard threatened to open a major can of whoopass on photogs ... in the form of a stun gun.

The altercation went down right after Sir Paul and Dave Grohl were wrapping up a double date for dinner at Crossroads restaurant.

McCartney was stepping into his chauffeur driven ride ... and the bodyguard clearly thought the paparazzi were getting a little too close, 'cause he barked out ... "Don't make me use my stun gun!"

Oksana Grigorieva forgot she's bankrupt and no longer dating a famous dude ... because Sunday night in Hollywood she tried getting into the post-Oscar Vanity Fair party -- and got SHUT DOWN!!

Mel Gibson's ex and some friends attempted to enter the party but none of them were on the list and the doorman wasn't having it ... so they took the walk of shame back to their ride.

Maybe they were worried she'd start recording the celebrity action inside.

Sorry Oksana, better start hunting for a new sugar daddy somewhere else.

The director of the Oscar Winning live-action short "Helium" may have been high himself ... telling our photog his Oscar will become a canine toilet.

Anders Walter and producer Kim Magnusson were leaving a post-Ocscar party at Ago in West Hollywood ... when Walter talked about losing the doggie door in his home and jerry-rigging a statuette to accomplish the function ... and he fully expects his dog to mark his Oscar territory.

And then ... Walter dropped the best humble brag of the evening.

If you thought the Academy Awards were dragging on and on ... you're not alone ... even Oscar nominee Amy Adams got caught checking her phone during the show.

To be fair, Amy could have been staring at her crotch -- but we're gonna go out on a limb and say she was more than likely texting some other famous person about how the show is putting her to sleep.

We're guessing she's not the only one.

Former Tiger Woods mistress Joslyn James is such a terrible mother, she's made a government "Most Wanted" list for bailing on nearly $20k in back child support ... TMZ Sports has learned.

Years before she banged Tiger, Joslyn -- real name Veronica T. Siwik -- gave birth to a son (now 14) ... and since she was the breadwinner in the relationship, she was ordered to pay child support to the dad.

But instead of paying up, Joslyn (a professional porn star) did what she does best ... screwed everyone ... and according to the Washington State Division of Child Support, she owes $18,419.86 in unpaid support.

James even made the division's "Most Wanted" list ... meaning she's in the top 100 of the state's 370,000+ child support cases. What an accomplishment!!!

A spokesman for DCS tells us the list is "the worst of the worst. It signifies you've made no effort. If you're currently making any payments, you're not on the list."

We reached out to Joslyn for comment -- and a rep told us the state must be mistaken -- "It's unfounded."

Joslyn's rep adds, "She loves her child. She's a doting mother."

Sure she is.

Simon Cowell is drawing a line in the sand ... paparazzi who want a piece of him will have to answer to his bitches.

Cowell's Yorkies -- Squiddly and Diddly -- aren't taking crap from the photogs who got their owner in trouble earlier in the week for allowing them on the beach in Miami. Cops gave Simon a warning ... one which he clearly didn't heed.
