Amanda Bynes Troubling Behavior

Amanda Bynes is in for a tough road ahead -- dealing with what looks like a serious mental illness and a conservatorship -- but she's not going to be charged with another crime ... TMZ has learned.

Law enforcement sources tell TMZ ... prosecutors will NOT charge Amanda with trespass, arson or any other criminal offense in connection with Monday's bizarre driveway blaze. We're told cops and prosecutors view her conduct as non-criminal and rooted in mental illness. We're told the cops almost immediately decided Amanda needed professional help -- not punishment.

But the troubled star is not out of the woods. She faces DUI charges in L.A. and reckless endangerment and pot charges in NYC.

Amanda Bynes is exhibiting signs of schizophrenia ... and medical professionals and others WILL seek a 2-week extension on her 5150 psychiatric hold so doctors can properly diagnose her ... sources familiar with the situation tell TMZ.

We're told ... ever since Amanda was taken into custody Monday night -- after she lit a fire on an elderly woman's driveway in Thousand Oaks, CA -- people close to Bynes are convinced she's suffering from mental illness, specifically schizophrenia.

Sources tell us ... Amanda's parents will now ask a judge to put the 27-year-old in a conservatorship, a la Britney Spears, because they believe she is unable to care for herself and could be a danger to others.

Amanda's parents have wanted to take action for the past couple of months -- but they didn't have the goods because Amanda's conduct was not so over the line that a judge would take away her freedom.

Now, after the driveway fire incident ... the circumstances may have changed enough to convince a judge Amanda needs help and supervision.

7:18 AM PT -- THE DOG IS SAFE!!!!! Law enforcement officials tell TMZ ... Amanda's dog was claimed by her parents after she was placed on a 5150 hold.

Amanda Bynes accidentally drenched her pet Pomeranian with gasoline while building a fire in a residential neighborhood ... then raced to a nearby liquor store to clean the pooch ... and TMZ has the bizarre footage.

The surveillance video -- taken inside the liquor store -- begins minutes after Bynes allegedly used a canister of gasoline to fuel a fire outside a random elderly woman's home in Thousand Oaks, CA around 8:38 PM on Monday night.

At 8:39 PM ... Bynes can be seen bursting into the liquor store and darting straight for a restricted "employees only" area -- while holding the dog in her outstretched arms.

The cashier -- sensing something was wrong -- rushed out from behind the register and chased after Bynes to see what she was doing.

TMZ spoke to the owner of the store who tells us ... the cashier detected a strong odor of gasoline and observed Bynes attempting to rinse off the dog in a sink in the back area.

We're told ... as soon as the cashier confronted Bynes, she "freaked out" and left the store without further incident.

Moments later, cops located Amanda and placed her on a 5150 psychiatric hold believing she could pose a danger to herself and/or others.

Amanda Bynes' parents REFUSE to pay for the fire damage their daughter allegedly caused on a neighbor's driveway late Monday night ... telling TMZ it's Amanda's mess to clean up.

We spoke with Amanda's father who tells us he has no intention of paying for any damage or cleanup related to the blaze ... saying, "Amanda needs to pay for it."

TMZ broke the story ... cops believe Amanda used a gas canister to ignite a small blaze in the driveway of an elderly widow who lives in the same neighborhood as Amanda’s parents in Thousand Oaks, CA.

That woman, Bonnie Braaten, turned down an offer from a neighbor who volunteered to power wash her driveway and clean up the mess from the fire. Braaten thinks Amanda’s parents ought to pay for the cleanup ... but clearly, the feeling ain't exactly mutual.

Amanda is currently hospitalized involuntarily on a 5150 psychiatric hold -- while officials examine her mental state.

Amanda Bynes didn't just build a fire in a driveway Monday night ... she put a flaming cloth on top of a gas tank ... effectively creating a makeshift explosive -- this according to an eyewitness 911 call.

The caller describes it as a small fire -- a flaming cloth sitting on top of a gas tank in a residential driveway. He says the reason he called 911 is because of the gas tank ... i.e. the obvious possibility of a massive explosion. The caller says he couldn't tell if the gas tank was full or not.

The eyewitness also spoke to reporters earlier today, saying he found Bynes lying down near the driveway with her left pant leg on fire. He says she quickly put out the flames and didn't appear injured, but she said her dog had been burned.

His story is pretty crazy -- after he confronted Amanda about the fire, he says she took off and got into a cab. You gotta listen.

8:35 AM PT -- TMZ just spoke to the woman whose driveway Amanda built the fire on, and she tells us, she had no idea what was going on until cops knocked on her front door. She says cops asked her, "Do you know anyone by the name of Amanda Bynes, or why she would have some vendetta against you?" She said no ... not surprising because the woman is elderly.

Cops then described to her that there was a young lady in her driveway, who had lit a fire and was carrying a little red gas tank. The homeowner says cops told her Amanda had burned part of her clothing.

Amanda Bynes is currently hospitalized on a 5150 hold ... after starting a small fire in the driveway of some random person's house Monday night, TMZ has learned.

Law enforcement sources tell us, the fire department responded to the home in Thousand Oaks, CA around 9 PM -- near where Amanda was just accused of trespassing -- after someone noticed the small blaze in the driveway. The sheriff's department was subsequently called when Amanda was found standing near the campfire.

When sheriff's deputies arrived, they questioned Amanda about what she was doing, and why she was doing it -- and based on her answers, they determined she needed to be hospitalized on a 5150 hold. Translation: her answers were really wacky.

A 5150 hold is an involuntary hospitalization for mental evaluation. Amanda can only be held for 72 hours though.

Britney Spears was famously taken in on a 5150 in 2008 during her pre-conservatorship period.

And just to give you an idea of what Amanda looked like yesterday, these photos were taken at Bloomingdales in Santa Monica just hours before the hospitalization ... around 5 PM.

Story developing ...

Cops confronted Amanda Bynes outside a retirement community after she got into an argument with a cab driver Sunday night ... TMZ has learned.

According to the cab driver ... Amanda was trying to get into an old folks home in Thousand Oaks -- outside L.A. -- when management at the place turned her away because they felt she was drunk and accused her of trespassing.

However, the retirement community was nice enough to call a taxi for Amanda -- but when she got into the cab she said ... "Get me the f**k out of here ... I don't have any money." Naturally, the driver kicked her out at that point.

We're told Amanda walked back toward the retirement community ... and that's when cops were called.

There's no record of Amanda getting arrested ... so, we're guessing she might have only been ticketed, possibly for trespassing.

Amanda grew up in Thousand Oaks -- and owns a house in nearby Calabasas.

The cab driver tells TMZ ... he was told Amanda was at the retirement village to visit a relative.

Mmmmmmm Ritz -- TMZ has learned, Amanda Bynes ran up a super stoner bill at the Ritz-Carlton in NYC this week ... ordering more than $2,000 worth of room service before getting the boot on Thursday.

As we reported, Bynes was ejected from the hotel for smoking weed inside her hotel room, as well as for being intolerably rude to hotel staff. Bynes denied the allegations, but her hotel bill, obtained by TMZ, appears to back up the hotel's story.

According to the bill, Amanda racked up nearly $9,000 in charges, staying in a $700-a-night room -- and $2,389 of that bill came from room service orders.

The bill shows Amanda placed nearly FORTY (40) separate room service orders -- and we're not talking a side of fries here and some nachos there ... each order averaged roughly $60-70 a POP.

Amanda Bynes was unceremoniously ejected from a Ritz-Carlton in NYC Thursday after allegedly smoking weed in her hotel room and being so rude to hotel staff ... she made one poor girl cry ...sources tell TMZ.

Amanda begs to differ, telling us she left the hotel voluntarily -- and does NOT smoke weed.

Our sources say Amanda was a nightmare from the get-go, smoking weed everyday despite warnings from hotel staff. We're told Amanda tried using spray chemicals to mask the weed smell.

But that's not it ... we're told Amanda was unspeakably rude to the hotel staff, telling the front desk girl she was "too ugly" to check her in. We're told Amanda then offered her plastic surgeon's services to the desk girl in question ... and the tears started flowing.

The bad behavior continued until Thursday .... Amanda was scheduled to check out at noon, but the hotel staff had had enough ... and kicked her out several hours before mandatory check out.

In case you're wondering where Amanda's going next -- we're told she was last seen getting into a cab headed to LaGuardia Airport ... bound for L.A..

Amanda Bynes secretly wants to be just like Miley Cyrus ... at least in the grill department ... so says the man hired to construct her gangster bling, Ben Baller.

Ben is the artist making Amanda's mouth piece -- which he says cost her $10,000 -- and recently Instagrammed a mold of the actress' chompers. So when our pap saw him out in NYC ... he HAD to ask ... what was it like working with crazy the future rapper?

Ben says it was a trip -- watch the video -- he goes into detail about her nutty behavior.

But more shocking ... Ben also revealed Amanda's number one request for her grill, explaining how she wanted it to be just like Miley Cyrus'. Interesting considering Amanda previously blasted Cyrus on Twitter as "Ugly."

Talk about a 180.

Amanda Bynes ... still not a fan of Barack Obama.

... and that's your daily AB update.

Amy Schumer wants Method Man to Wu her Tang ... seriously.

The Comedy Central star was at LAX recently -- where she seemed shocked by her meteoric surge in fame -- but still took time to talk to TMZ about vaginal homicide ... a la Amanda Bynes.

Amanda Bynes rolled into a New York courtroom today dressed more for a rave than a court hearing -- sporting an aqua-colored wig, sweatpants, a tank top ... and sneakers!

... and no one was surprised.

Bynes was in court to fight allegations she threw a glass bong out of her NY apartment window back in May.

According to police, Amanda threw the bong out of her window before they arrested her, but she has denied the accusation ... in fact, she says the arresting officer sexually assaulted her by slapping her vagina.

She also said cops entered her apartment illegally.

Aspiring rap star Amanda Bynes doesn't need street cred, 'cause she's got something way more powerful -- DISNEY CRED ... this according to her new hip hop partner Waka Flocka Flame.

WFF was heading into the WME agency in Beverly Hills yesterday when we asked about his plans to help launch Amanda's rap career into orbit.

FYI -- Bynes was a Nickelodeon star, not Disney, but we think we get Waka's point.

According to Flocka, things are going so well ... he's already given Bynes an official RAP NICKNAME!!

Forget Wyclef Jean ... Amanda Bynes is hashing out a record deal with rapper Waka Flocka Flame for her upcoming hip hop album -- and Waka tells TMZ, it's going to be legendary.

Waka -- who runs Brick Squad Monopoly records -- tells us, the deal hasn't been signed yet but it's basically in the bag ... in fact, he's already hired people to start penning Amanda's songs.

Waka says he and Amanda FaceTime at least once a week and text every day -- mostly about her rap career ... but also about motivational stuff, like "keeping her head up from the haters."

Waka tells us the album will be called "Shots" -- adding, "It's going to be crazy hot." So far, there's no projected release date.

As for whether Waka thinks there's something a little off about Amanda ... he said, "Not at all. She has it all together to me. She is cool as hell and ready for the rap world. I think she is going to kill the game."

And just to make sure it's a success ... Waka says he'll be featured on several of Amanda's songs as well.

Amanda Bynes won't be releasing an album with Wyclef Jean's help any time soon -- reps for the former Fugees rapper tell TMZ, Clef has NO intention to collaborate with the wig-wearing tornado of confusion.

There were reports Bynes and Wyclef would be joining forces for Amanda's upcoming album on Chinga Chang records -- after the label's CEO Daniel Herman went on the record saying he was bringing the two together for an explosive collaboration.

But Wyclef's management says it's just not gonna happen, telling TMZ, Wyclef has no intention of working with Amanda.

In fact, Wyclef's people say he's never even spoken to Amanda.
