Nurse!

3 of Willie Nelson's band members were hospitalized this morning after their tour bus crashed in Texas ... and the band's blaming it on an icy road.

The band's bus (Willie was in his own ride) crashed along I-30 around 3:30 when it hit a bridge pillar -- about 80 miles east of Dallas.

The most severe injury ... a broken hip. The other two guys walked away with bumps and bruises.

A rep for the band says the next four shows have been cancelled.

On the road again.

10:00 AM PST -- This is a photo of the gnarly damage.

"Simpsons" star Marcia Wallace's family denied breast cancer had anything to do with the actress' death ... but according to her death certificate, the disease played a significant role.

TMZ obtained a copy of Wallace's death certificate ... which lists pneumonia, sepsis (inflammation due to infection), and chronic obstructive pulmonary disease (COPD) as the primary causes of death.

The report also says breast cancer was a "significant condition" contributing to her death ... despite the fact Marcia's son initially downplayed reports mentioning cancer.

Dina Lohan has something going on in her head, and the judge in her DUI case wants to know the contents ... because he just ordered a full psych evaluation.

Dina was in court this AM for her DWI case. Her lawyer, Mark Heller, claims she's alcohol free but the judge isn't necessarily buyin' what he's sellin'.

So now Dina has to get her head shrunk by a court-appointed shrink.

Lohan pled not guilty to DWI in Sept. ... after blowing a .20. Heller blamed Dina's legal predicament on the paparazzi ... claiming Dina is stressed out by the mob of photogs that follow her ... and that's what caused her to flee in a drunken state.

The judge did not impose a sentence today -- he'll wait for the psych report -- but he did say he's considering a stiff penalty -- revoking her driving privileges for 12 months ... and 100 hours of community service.

Brit singer Rita Ora is profusely apologetic for freaking out her fans ... after collapsing on the set of her photo shoot in Miami.

Rita -- who's Rob Kardashian's ex-GF -- looked the picture of health last night at Miami International Airport ... where she flew home to London.

As we reported ... Ora was treated for heat exhaustion after Monday's fainting spell. She's been laying low at her hotel for the last couple of days.

Before saying cheerio to the US ... Ora said she's all better now ... and had a message for her fans.

Amanda Bynes is mentally capable of understanding the nature of the criminal charges she faces, and as a result the road is now clear for her to stand trial for DUI.

Amanda's case was in Mental Health Court this AM, and the judge read the court-ordered medical evaluation of the actress, and determined she is now competent to face the DUI charges.

Amanda's lawyer, Rich Hutton, did not object to the findings so the criminal case -- which was put on hold -- will now go forward.

Sources say the ruling will have NO impact on her conservatorship. Fact is ... even though Amanda is capable of understanding the nature of legal proceedings, she is nowhere close to being able to care for herself.

As for the DUI case ... no way will it go before a jury. It has plea bargain written all over it.

As we first reported ... Amanda has been diagnosed with Schizophrenia and bipolar disorder.

Ex-Disney star Jake T. Austin WAS the driver of the car that crashed into 3 other vehicles early Tuesday morning -- but because of some swift and clever legal gymnastics by his lawyer, Jake may actually avoid prosecution ... TMZ has learned.

Here's the way it went down -- sources intimately familiar with the situation tell TMZ, 18-year-old Jake and a friend were driving in Studio City around 3AM when he crashed into the 3 cars.

Witnesses say Jake tossed a Ciroc vodka bottle out of the car, but before cops arrived at the scene, we're told Jake ordered an Uber (Town Car service) ... and he and his friend high-tailed it out.

Cops suspect drinking was involved, but there's no way Jake could be prosecuted for drunk driving because police never located him. And, we're told, Jake denies he had been drinking.

But drinking aside, Austin is still in trouble for leaving the scene of an accident without providing identifying information ... which constitutes a hit-and-run. But Jake's lawyer pulled off some legal acrobatics that could get Jake off the hook.

We're told the lawyer called cops at 4am and told them Jake was the owner of the car. Cleverly, the lawyer did NOT disclose the fact that Jake was the driver ... so as not to violate the attorney-client privilege, especially important because leaving the scene is a crime.

And here's where it gets really good -- we're told Jake has an iron-clad excuse for leaving the scene: he and his passenger were injured and needed immediate medical attention. In other words, they didn't have time to leave a note.

We're told Jake had an injury to his mouth, and went directly to the ER and received stitches.

And the coup de grace, we're told Jake's lawyer has made it clear ... the victims will be fully compensated ... so there's really no need to prosecute.

The legal maneuvering might have saved the lawyer a huge headache on multiple fronts -- he's also repping Jake after the kid's DUI arrest last month.

Casey Kasem's children will NOT assume control over their ailing father's life -- at least not yet -- a judge just denied their request for a temporary conservatorship ... TMZ has learned.

The Kasem kids went to court to show that Casey's wife Jean is not providing the care he needs ... and banned his own children from seeing him.

But a judge denied their request for an emergency conservatorship ... saying he has confidence the issue of visitation with the children can be worked out by attorneys on both sides.

The judge also said a temporary conservatorship is not necessary because Casey -- who is suffering from advanced Parkinson's -- is NOT "at risk" and is getting proper treatment at home.

As we reported, Jean offered the kids a deal ... drop their bid for a conservatorship ... and in return they would each get regularly scheduled, though brief, visits with Casey and notification when he's hospitalized.

Camille Grammer is pissed off that her ex-boyfriend -- the guy who she claims beat her to a pulp -- is making his case to the media and AVOIDING doing the same in a court of law.

Grammer's lawyer, Larry Stein, just filed legal docs claiming Dimitri Charalambopoulos has been avoiding getting served with legal docs notifying him that he's required to stay 100 yards away from Camille.

Stein says he and his P.I. have been on Dimitri's tail, but he's been evasive ... but not so evasive as to turn down a chance to go on TV and explain that he's really a good guy who did no harm.

Stein wants the judge to decree that Dimitri is aware and bound by the restraining order.

9:39 A.M. PT -- NeNe just posted a message on her website saying she went to the hospital after feeling short of breath... and was diagnosed with blood clots in her lung. She says she's recovering at home now and she's "thankful to be alive." She also reassured her fans she did NOT have a heart attack.

"Real Housewives of Atlanta" star NeNe Leakes was hospitalized this week for a mystery illness ... and the reality star says she's "blessed to be alive."

NeNe posted a photo of herself in a hospital room on Monday with IVs in her arms along with the caption, "My arms are hurting wit these IV’s #blessedtobealive."

Just one night before she tweeted that she had been sick for the past couple of days ... but never specified what she was suffering from.

There's one more clue -- one of NeNe's followers tweeted that he thought Leakes was suffering from exhaustion due to her "grueling schedule" ... and NeNe rewtweeted the message, adding, "I work my butt off."

Story developing ...

Things are getting darker in Casey Kasem's world. Casey's 3 kids from a previous marriage have REJECTED a settlement offer proposed by Casey's wife, Jean.

Sources connected to the case tell TMZ ... Jean asked the kids if they would drop their lawsuit for a conservatorship if she would do the following:

-- Give the kids the right to visit their dad, with strings attached. Each child would have separate visits every 3rd Sunday for 1 hour. A security guard would be in the general vicinity during the visits. The children have to give 72 hours notice before each visit.

-- The kids could also visit during Thanksgiving, Hanukkah, Christmas week, Easter Week and his birthday.

-- If Casey is hospitalized, the kids will all be notified. It doesn't provide they can visit him in the hospital.

Casey is quite ill with advanced Parkinson's and the early onset of dementia.

Sources say Casey's kids -- who have not been allowed to see their dad and have filed legal docs to win a conservatorship -- have turned thumbs down on Jean's offer.

The Make-a-Wish Foundation has a message for the cold-hearted jerks who complained Batkid didn't deserve his bat-wish because he's in remission -- HOW DARE YOU?!!

If you haven't heard, Make-A-Wish really outdid itself -- turning San Francisco into Gotham City for 5-year-old cancer patient Miles Scott, who wanted to be Batman for a day.

Miles has been battling lymphoblastic leukemia since he was 20 months old, but some (heinous) people on the Internet have had the audacity to say he didn't deserve his wish because he's currently in remission.

Make-A-Wish rep Josh deBerge says that's just wrong, telling us ... "We would never penalize a child for getting better."

And Josh says that's all that matters.

Suck it, haters.

Ashley Greene is being sued over the fire she started in her West Hollywood apartment that killed her dog and injured the man who helped rescue fleeing residents.

Adrian Mayorga just filed a lawsuit against the "Twilight" star -- obtained by TMZ -- in which he claims he was hurt while running through the smoke-filled hallways, while yelling and screaming for residents to flee.

The doorman claims he suffered exhaustion, dehydration and smoke inhalation and ended up in the hospital.

Four residents in neighboring units have also sued, claiming the fire wreaked havoc on them with soot and water damage.

British pop singer Rita Ora -- who had the hit song, "R.I.P." -- collapsed on the set of her photo shoot in Miami Beach today ... and was rushed to a hospital by ambulance according to photographers on the scene.

Photos show the 22-year old singer/model/actress -- eyes closed -- being unloaded from the ambulance on a stretcher ... attended by emergency personnel. So far, no word on what may have caused her to collapse.

Ora -- who famously dated Rob Kardashian last year -- was reportedly preparing for her photo shoot on the beach near the SoHo Beach House hotel when she fainted in her makeup trailer.

We've reached out to Rita's people -- so far, no word back.

2:01 PM PT Ora's doctor, David Farcy, tells TMZ Rita was treated for heat exhaustion and dehydration. She's been discharged and Dr. Farcy says she's fine. She flashed a big smile to fans when she returned to her hotel from the hospital. Rita was in the middle of a photo shoot for Madonna's Material Girl campaign in Miami when she was taken ill.

Reason #427 to avoid mosh pits at rap concerts -- rappers like George Watsky launching themselves like a missile into the crowd from 35 feet in the air!

Watsky -- an up and coming rapper from San Fran -- was performing in London on Sunday when he climbed onto the light rigging above the stage, and hurled himself into the first few rows of the crowd.

Watsky survived with just some bad bruises ... but his fans didn't do so well. A woman in the audience broke her arm, and a guy suffered back injuries.

Jake Gyllenhaal trotted out his bandage-wrapped hand in Hollywood yesterday ... just days after he was rushed to an ER for slicing his mitt on a mirror.

Jake attended a screening of "Prisoners" Friday night -- and laughed it up during a Q&A for his movie ... seemingly unfazed by the injury.

As we previously reported ... Gyllenhaal "flipped out" while filming a scene for a movie called "Nightcrawler" and punched a mirror. The cut was so bad he needed stitches.

The 26-year old wrestler fainted in the ring Friday while wrestling Brie Bella in London, and dehydration was to blame.

According to reports AJ -- real name April Mendez -- was tended to at ringside after the scary fall ... and walked to the back on her own power.

We're told WWE medical staff continues to monitor her ... just to be on the safe side -- and also because she's really hot.
