Charlie Sheen allegedly jumped out of a dental chair last week, pulled his nitrous oxide mask off and grabbed the dental tech's breast ... so she claims in a new lawsuit -- claims that Charlie says are absurd.

Margarita Palestino alleges in her new lawsuit, Charlie came to the office last week for a procedure that required nitrous. As she put the mask on him, she says he ripped it off, jumped out of the chair and yelled, "I'm going to f***ing kill you!"

She says she continued trying to put the mask on, and this time he grabbed her left breast and pulled her scrubs, then grabbed her bra strap and tried pulling it down.

Palestino says Charlie came to the office "incoherent" and she says the dentist told her Charlie was high on crack cocaine ... something Charlie says is absurd.

She also says Charlie lunged at one of the dentists with a knife and then started stabbing the dental chair.

And Palestino says on their way out Charlie's assistant offered her $500 for her troubles.

As TMZ first reported ... the dentist has told cops Palestino is lying and nothing of the sort happened, and he accused her of blabbing that Charlie was a patient -- a violation of HIPAA.

Ex-Titans kicker Rob Bironas was hammered -- with a blood alcohol content njearly 3 times the legal limit -- the night he wrecked his SUV and died in Nashville.

The toxicology report shows Bironas' BAC was .218 when he died on September 20. Police released test results to his family today. The report also revealed he died from blunt force trauma ... and had a small amount of Diazepam (Valium) in his system.

Rob's wife, Rachel -- who is Terry Bradshaw's daughter -- told police Rob might have had one beer at home that night ... before he unexpectedly took off in his vehicle without telling her.

Amanda Bynes is off to NYC ... and she is not well.

Amanda was at LAX Thursday night at an airport restaurant, acting bizarre, painting her face with excessive amounts of makeup.

Sources connected to Amanda tell us she was visibly high all day, talking to herself and complaining about her life.

The pics below are from a Thousand Oaks, CA hair salon, where Amanda got a dye job. She was there for several hours -- again acting bizarre -- before heading to the airport.

We believe she is now in NYC.

Charlie Sheen just lashed out at the dental technician who accused him of going after her boss, calling her "a jobless, washout traitor."

TMZ broke the story ... the LAPD is investigating Charlie after the technician told them Charlie attacked her last week while he sat in a dental chair. She claims his security guard told the dentist Charlie was high on rock cocaine and says Charlie went after the dentist with a knife.

Charlie is furious, giving TMZ a message for her, saying,

"Hey cholesterol pants: Maybe you should have taken the crack you so brazenly and ignorantly accused me of being on, and sold it! Now that you're a jobless washout and a traitor, you're gonna need the extra dough ... lick those food stamps, you desperate troll. C."

Fact is, her story doesn't make a lot of sense. The dentist denies her story and fired her because she blabbed about Charlie coming in, which violates HIPAA. And it makes NO sense Charlie's security guy would blurt out he was high on rock cocaine.

Charlie's lawyer Marty Singer calls the allegations "completely fabricated." He adds, "No bodyguard made the absurd statement to the dentist. Charlie had a bad reaction to the noxious gas put in his mouth and nose."

Charlie Sheen clearly doesn't like going to the dentist, because he's under investigation for assault with a deadly weapon for allegedly going nuts in a dental chair in a rock cocaine-fueled rage ... TMZ has learned.

Law enforcement sources tell us ... Charlie was at an L.A. dental office last Thursday for an abscess. He sat in the chair as the dental technician placed a mask over his face to administer nitrous oxide, when she says Charlie went insane ... flailing his arms and striking her.

The technician told cops she walked out of the room as Charlie's security guard entered. Charlie's personal dentist was there along with the oral surgeon. There was a lot of commotion and the technician says when Charlie's dentist finally came out he told her Charlie pulled a knife and went after him. The dentist wasn't hurt.

The technician also told cops the bodyguard told the dentist Charlie was high on rock cocaine.

We're told there's an active LAPD investigation and cops are looking at a possible battery against the technician and felony assault with a deadly weapon for the alleged knife attack on the dentist.

We're told cops want to interview Charlie and the dentist before sending the case over to the L.A. County D.A., who will decide whether to prosecute.

We reached out to Charlie ... so far, nothing back.

Former NFL wide receiver Reche Caldwell now admits he shipped and received more than a kilo of molly through the mail -- and he's facing SERIOUS jail time for it.

Caldwell pleaded guilty Wednesday in Tampa to possession and intent to sell a huge stash of ecstasy pills, according to the U.S. Department of Justice.

Prosecutors say the plea was part of a deal Caldwell hammered out with them -- but details of the deal were not immediately released.

As we told you ... Caldwell was busted in May for trying to send 2 separate packages in the mail filled with the party drug. The ex-Chargers, Patriots, and Redskins player faces up to 20 years in federal prison. That's the max, but considering he worked out a deal ... that seems unlikely.

Stephanie Seymour's socialite son may think about a move from NY to Colorado ... because then he wouldn't have gotten busted for weed.

Law enforcement sources tell TMZ ... 20-year-old Peter Brant Jr. was popped by cops in Red Hook, NY ... and charged with misdemeanor possession of weed. Cops wrote him a ticket and let him out.

The fine shouldn't pose much of a problem ... his dad's a billionaire businessman.

And his mom is a super affectionate ex-supermodel.

Amanda Bynes was out of control at her fashion school ... showing up high and offering fellow students money to do her homework ... and we're told it got so bad she was kicked out.

Several classmates at the Fashion Institute of Design and Merchandising in Irvine say Amanda has shown big signs of trouble for a while ... and various people have told us she often went to class high on weed.

Student Rachel Loritz tells TMZ ... Amanda often ditched classes ... but even when she showed up, she was clearly high, and not good at hiding it ... she almost always wore sunglasses and laughed out loud at inappropriate times.

We're told the pendulum would often swing and she would then get in "horrendous arguments."

Rachel says ... Amanda paid fellow students to do her homework ... and some took her up on it. Rachel says she rejected Amanda's offer.

We're told Amanda was caught cheating off someone during a test ... and when she was called out she threw a fit.

Michael Phelps had just finished up an 8-hour gambling session at a Baltimore casino before he was popped for DUI early Tuesday morning ... TMZ Sports has learned.

According to our casino sources, Phelps hit up the Horseshoe Casino around 5pm Monday afternoon ... and sat in a private VIP gambling room for hours ... finally leaving around 1am.

We're told Phelps was playing blackjack ... though it's unclear if he also played other card games that night. There have been several reports that he's big into poker.

Clearly, Phelps had been drinking inside the casino ... we're told his booze of choice was beer ... and when he was pulled over around 1:40am, it was just a few miles from the casino.

We're told Phelps is a regular at the casino ... in fact, he was just there last month playing poker.

We reached out to Phelps for comment -- so far, no dice.

Amanda Bynes can't get the help she needs until something really bad happens ... because her parents will not re-establish a conservatorship ... TMZ has learned.

Multiple sources connected with the family tell TMZ ... Amanda's parents do NOT think she has a mental illness. As one source put it, "They think she's a bratty kid who thumbs her nose at them and smokes a lot of pot."

We're told everyone around her parents are urging them to get the conservatorship, but so far no luck. That said, it's impossible to put Amanda on a 5150 psychiatric hold until she creates a substantial risk to herself or others.

We're also told various professionals are trigger ready to get the 5150 if Amanda goes off the rails, and they believe it's only a matter of time.

Machine Gun Kelly parties HARD ... but his legendary tales of getting wasted can't be used against him when he goes to court for allegedly slicing open a guy's finger during a nasty bar brawl.

Kelly's being sued by a bouncer who claims the rapper nearly took his digit off cleanly ... when he fired a liquor bottle at him during a massive fight at a St. Petersburg, FL tavern in 2012.

Michael Phelps was arrested for driving under the influence in Baltimore, Maryland early this morning ... TMZ Sports has learned.

Our sources tell us ... the USA Olympic legend was pulled over around 1:40 AM in his white Land Rover. We're told he bombed his field sobriety test ... and his B.A.C. was almost twice the legal limit.

Officials just issued a statement saying Phelps was initially pulled over for going 84 in a 45 ... and during the stop, the officer noticed he was hammered.

Our sources say Phelps was hauled to a nearby station where he was booked for DUI -- and was eventually released.

Cops say Phelps was charged with DUI, excessive speeding and crossing double lane lines.

It's Michael's 2nd DUI arrest -- he was popped in Maryland in 2004 when he was 19 years old. He struck a plea deal with prosecutors and pled guilty in exchange for 18 months probation.

We've made multiple calls to Michael's reps -- but they would not take our calls.

1:00 PM PT -- Michael is now apologizing for the arrest.

Mega-popular EDM group Krewella has no place for people who don't party ... because a former member claims he was kicked out for being too clean.

Kristopher Trindl says he formed Krewella back in 2010 with former girlfriend Jahan Yousaf and her sister, Yasmine ... but now says the women want to morph the group into a duo. In a new lawsuit, Trindl says the girls came up with a lame reason for kicking him out ... that he acts too depressed.

Trindl partied plenty before he went to rehab last year. After rehab, he says the women started treating him differently ... and he believes it's because he became a teetotaler.

He does admit relapsing twice and missing a major event -- the Electric Daisy Carnival. Hmmm.

Trindl says to add insult to injury, the girls put up a billboard of themselves on the Sunset Strip.

Trindl says when he came back from rehab, the sisters didn't like the new, sober Kris ... because he no longer drank and partied. He claims they even staged an intervention -- to try to force him into rehab again -- because they thought he was depressed and needed treatment.

He says it's clear ... they just want him gone so they can take his one-third share of Krewella's earnings. He is suing the sisters for more than $7M in damages.

The parents of Amanda Bynes are in the dark about their daughter's arrest and have no idea where she is or what she's been doing since her conservatorship ended.

Bynes' father Rick said he and his wife learned about Amanda's arrest from the media ... they weren't the ones who bailed her out. Rick repeatedly said, "We don't know," when asked about Amanda.

It's interesting … Rick said he thought his daughter might be in New York, but TMZ has learned she's staying in the Hollywood area right now.

As TMZ first reported, Amanda moved out of her parents' house once the conservatorship ended earlier this month … but many people close to Amanda feel it was a terrible mistake not to extend it.

We're told Amanda is smoking a lot of weed and is off her anti-psychotic meds for Schizophrenia and bipolarity.

Amanda Bynes was under the influence of Adderall when she was arrested for DUI ... sources familiar with the situation tell TMZ ... but her problems go much deeper than a criminal case.

We've learned the Adderall was prescribed by a doctor and she had taken the drug before getting stopped in Van Nuys Sunday and failing multiple field sobriety tests. She was arrested for DUI.

Adderall is a stimulant and we're told Amanda was "out of it" when she was stopped.

Fact is ... it's no defense to DUI that the drug in question was prescribed -- it's still operating a vehicle while impaired. But Amanda now faces a probation violation -- she's on probation for reckless driving -- and the fact that the drug was prescribed may help her there.

The deeper problem is this ... As TMZ first reported, Amanda has moved out of her parents house and is now living in Orange County. We're told she's smoking a lot of weed and is off her anti-psychotic meds for Schizophrenia and bipolarity.

Amanda's conservatorship ended earlier this month and we're told her parents saw no need to extend it because they believe she's better now, but everyone else in her life feels it was a horrible mistake to let the conservatorship lapse and they fear for Amanda.

Amanda Bynes was arrested in Los Angeles Sunday after cops determined she was driving under the influence ... and our law enforcement sources say she was on a STIMULANT ... but we're told she has also developed a serious weed problem ... again.

Here's what we know -- Bynes was driving a Mercedes in the San Fernando Valley when she stopped in the middle of an intersection on Van Nuys Blvd.

A CHP officer spotted her and determined she was under the influence. She was taken to the LAPD Van Nuys division where a drug recognition officer determined she was under the influence of a stimulant. Toxicology tests are being performed now to determine the exact drug or drugs.

According to the incident report ... Amanda had a "disheveled" appearance.

Amanda was then booked for DUI. She posted $15,000 bail.

Amanda has had trouble with mental problems for years now. Her parents had a conservatorship which ended earlier this month and as one source says, "Things started going haywire."

We're told Amanda has moved out of her parents home and is now living in an Orange County apartment. We're told she has been smoking weed for weeks and things are bad again.

The arrest triggers a legal problem. Amanda is on probation for a reckless driving conviction last February.
