Nurse!

Richie Incognito was admitted to a psychiatric care unit in Arizona late Thursday night ... TMZ Sportshas learned.

"The Little Couple" star Jen Arnold is a free woman ... free of the cancer that wracked her body.

We got Jen and hubby Bill Klein in NYC ... and they revealed two major spoilers for the upcoming season of their TLC reality show -- including the latest on her battle with stage 3 cancer.

Jamie Lee Curtis frantically called 911 Tuesday night -- after her friend suffered what appeared to be some kind of overdose in the backseat of the actress' car ... TMZ has learned.

Law enforcement sources tell us ... paramedics responded at around 9pm in Venice, CA after receiving Curtis' phone call ... and found her friend passed out in the backseat.

According to sources, Curtis' friend had suffered a violent reaction after mixing alcohol with some kind of prescription Rx.

We're told Curtis initially tried to drive her friend to the hospital -- hence why the friend was in the backseat -- but she decided to call 911 instead when the situation took a turn for the worse.

Seth Rogen testified before a Senate subcommittee Wednesday and pledged allegiance -- to "House of Cards."

Seth went to Capitol Hill to voice his support for legislation to increase funding for Alzheimer's research. Seth's mother-in-law suffers from the disease.

By congressional standards, Seth was hilarious ... and a little too hip for the room.

Safe to say Senator Tom Harkin, Chairman of the Senate Appropriations subcommittee, is not a big fan of "Knocked Up" ... but he was clearly amused.

Check out the video. Pretty funny.

Amanda Bynes has turned it around in a big way ... and one of the markers is that she is now remorseful about things she did and said when she was at her worst -- particularly her comment about Drake, "I want Drake to murder my vagina."

Sources directly connected with Amanda tell TMZ ... she is in the territory of being her old self again. They say the fact that the Drake comment "horrifies her" shows she again has a sense of the difference between right and wrong.

But there's more. We're told Amanda has stopped smoking weed, she's in the process of removing a number of inappropriate tattoos, and she's kind to people with whom she interacts.

Most impressive ... Amanda is now at FIDM -- the Fashion Institute of Design Merchandising in Orange County -- and she's become so self-confident she makes presentations to her entire class and freely interacts with her classmates.

TMZ broke the story ... Amanda was diagnosed with schizophrenia and bipolarity. It's apparent the meds and the therapy are working.

Johnny Bench tells TMZ Sports he fully SUPPORTS the new anti-collision rule in the MLB -- but that doesn't make him a wuss. In fact, Johnny says he's still tough as nails ... and he's willing to prove it.

Johnny was out in D.C. Tuesday when he dropped some serious collision knowledge -- comparing speeding base runners to MISSILES who can seriously injure a catcher.

But when we asked if he still considered catchers "tough" -- the 66-year-old Hall of Famer challenged our guy to a collision right there on the spot.

Seriously, we're lucky our guy walked away in one piece.

Lindsay Lohan just kicked a nanny's ass.

A nanny sued Lindsay -- claiming she was pushing a baby stroller in West Hollywood when LiLo recklessly drove her Maserati smack into her -- but she just folded like the cheap suit she takes to the dry cleaners.

TMZ broke the story ... Nubia Del Carmen Preza filed the lawsuit back in 2012 for personal injuries -- the baby was not hurt. But the case lingered and the nanny just threw in the towel ... that she uses to clean the kitchen.

Former University of Miami football star Jojo Nicolas is in critical condition after his car crashed into a semi-truck in Miami Beach early Tuesday morning ... TMZ Sports has learned.

Jojo -- a former defensive back who played from 2007 to 2011 -- was driving a grey Lexus that slammed into the back of a truck.

TMZ Sports obtained footage from the crash scene which shows the Lexus wedged underneath the truck. He was eventually removed from the car and transported to a nearby hospital.

Our sources tell us ... Jojo is currently in critical condition -- and as one source puts, "It doesn't look good."

Jojo last tweeted Monday night ... saying he was attending a party at a Miami Beach nightclub.

Law enforcement sources tell us alcohol "has not been ruled out" as a cause of the crash ... and we're told officials are aware of where Jojo was prior to the accident.

Story developing ...

Robin Thicke is one sick dad.

Robin cancelled his concert Saturday at Orlando's Universal Studios because of voice problems ... but still pulled himself together to hit up Disneyland with his son.

Robin also canceled his Friday show in Atlanta. It's unclear specifically what ails him but whatever it is ... it must not be contagious because he spent most of the day Sunday waiting in long lines.

Disneyland ... where the lines are 95% of the fun.

"Biggest Loser" trainer Dolvett Quince still isn't happy with winner Rachel Frederickson's weight -- after she dropped from 260 to a scary 105 pounds -- but he tells TMZ, he's determined to get her healthy.

Rachel won Season 15 earlier this month ... but her dramatic weight loss shocked viewers, who claimed Rachel had lost TOO much weight, bordering on anorexic-looking.

And it appears Quince agrees -- he tells us, "We're going to get her healthy. She's going to be alright ... She's getting healthier every day."

Quince says he's still working with Rachel -- pro bono -- and has a plan to help her get better.

Ahmed Ahmed -- a well-known comic who stars in TBS's "Sullivan & Son" will NOT be charged with domestic violence ... TMZ has learned.

Ahmed was arrested last month after cops responded to a 911 domestic violence call at his house. Cops say his girlfriend had visible marks so Ahmed was cuffed and booked on felony domestic violence.

The case eventually made its way to the L.A. City Attorney for misdemeanor prosecution, but we've learned the City Attorney will formally reject the case today based on insufficient evidence.

As for the problems in the case ... we're told there is a witness who says the GF did NOT have visible marks on her body. Also, both the girlfriend and Ahmed called 911 which muddies the waters.

Stoners may frown on smoking a joint covered in ink ... but one Tyga fan says it's possible he may break that rule -- after the rapper jotted his John Hancock on the guys weed-filled zig zag.

Tyga was celebrating the opening of his new store Last Kings Saturday in Los Angeles ... and while snapping pics with fans, one guy asked Tyga to sign his ganja stick.

Afterward ... the guy doesn't quite say he'd never smoke it.

We called doctors across the country attempting to get an expert opinion on what kinda damage smoking ink can have on your lungs.

Jake "The Snake" Roberts has a cancerous tumor behind his knee ... and the wrestler says it's slowly growing into his muscle -- so he needs emergency surgery to remove the growth.

Roberts tells TMZ ... he noticed a tumor behind his knee the size of a half dollar last month so he had it tested ... and on Friday doctors told him the test came back positive for cancer.

Jake says he's scheduled to go under the knife Tuesday morning ... and after a few weeks off -- he'll make his return to Jersey Championship Wrestling on March 14th -- cancer, or not.

Jake adds, "If the devil can't defeat me, cancer doesn't stand a chance in hell! Pray for sick children who face this horrible disease 'cause The Snake will be just fine."

As for his upcoming induction into the WWE Hall of Fame ... the wrestler says nothing will stop him from getting to New Orleans for the ceremony.

The rattlesnake that killed "Snake Salvation" Pastor Jamie Coots a week ago made an encore appearance Saturday night at the same church with Jamie's son at the helm ... and this time no animals or people were hurt.

Cody Coots prayed over a bevy of snakes -- one of which was the rattler that killed Jamie. The video is insane ... it looks like a revival service with a live band and snakes and worshipers all flailing in the air.

As we told you ... Cody made it clear to us ... if the rattler bit him he would refuse treatment ... just like his dad.

But snakes weren't the only trick up Cody's sleeve. He also played with fire ... literally.

Bite me once shame on you ... the new pastor in the "Snake Salvation" church will NOT accept medical treatment today if he's bitten by the rattlesnake that killed his father exactly one week ago.

Cody Coots tells TMZ ... he will indeed handle the deadly snake during the afternoon Kentucky service. What's more, he says there will be NO anti-venom meds on hand in case the snake attacks again.

And ... if he's bitten and paramedics rush to the church, he'll send them away ... just like his dad Jamie Coots did.

Adam Lind -- who appeared on MTV's "Teen Mom 2" -- was pulled from the mangled wreckage of his Corvette Friday ... just moments before it exploded in flames.

Law enforcement tells us ... Lind was driving his 2001Corvette Z06 really, really fast in Sioux Falls, SD when he collided with a Lincoln Town Car. Cops say the Lincoln was driven by an 87-year-old woman, who had a 94-year-old passenger.

Some VERY good Samaritans saw the crash and ran to the mangled vehicles, pulling everyone out seconds before the Corvette lit up like a torch.

We're told Lind and the elderly couple were taken to a local hospital and treated for non-life-threatening injuries.
