Nurse!

"Street Outlaws" star Daddy Dave was thumbs up during his hospital stay ... even though he can't remember why he ended up there.

Dave's wife Cassi tells us Dave is healing up pretty well after the accident ... and was released from the hospital early Monday. He'll go back home to Oklahoma to recover.

We're told he's been having problems with his short-term memory after suffering a concussion from the horrific crash. He's been told numerous times what happened, but he keeps forgetting.

As we reported, the accident occurred Saturday.

Dave's lucky ... and his family keeps reminding him of that.

The bassist for Slipknot was rushed to the hospital by ambulance in the middle of the band's performance.

Alessandro "V Man" Venturella got onstage with the band Sunday night in Hartford, Connecticut but after a few songs the band abruptly stopped and went backstage. They returned minus V Man, and lead singer Corey Taylor told the audience, "I'm sorry to say that our bass player, Alex, had ... something happened."

We've learned Alex was rushed to the hospital for convulsions. It's unclear what his condition is this morning. The band continued its performance.

Slipknot's original bassist, Paul Gray, died in 2010 from an OD.

2:20 PM PST -- Daddy Dave's wife took to his Facebook to let fans know that despite a concussion, bruised lung and some bumps and bruises, Dave is recovering in his own room.

The video is horrific ... a drag race comes to a quick, violent end when Daddy Dave from "Street Outlaws" loses control of his vehicle and it slams into a wall and barrel rolls.

It happened at the Amarillo Dragway in Texas Saturday night. Dave was driving a nitrous-fed Chevy II and struck the wall seconds after the race started.

Janet Jackson has put her life on hold to take care of her dad while he recovers from 3 heart attacks, and she's the only member of the brood who made the trek to Brazil.

We're told Janet arrived in Brazil Tuesday to tend to her father, cancelling rehearsals for her upcoming tour. We're told Janet limited the access to ICU, where Joe was hooked up for nearly a week.

The good news ... Joe's now out of ICU and on the mend. He's eating solid foods and the goal is for him to regain enough strength so he can get on a plane and return to the U.S. for further treatment.

We're told La Toya and Jermaine were talking about flying over, but when Joe's condition improved they decided to wait until he came home.

If all goes well, Joe could return home as early as Monday.

Shawn was leaving a bar in Grand Bend, Ontario last week when Mickey allegedly hurled a brick from a second story balcony in Shawn's direction, hitting him in the head.

Canadian cops arrested Rapaport for assault with a weapon and busted Rapaport's son Justin as well ... for obstructing a peace officer.

Evans says he suffered a concussion and plans on suing.

L.A. Dodgers 3rd baseman Justin Turner shoulda oxy-cuted the massive pimple on his leg -- because it got infected ... and things got so bad, he was taken to the EMERGENCY ROOM!!!

It's pretty gross ... Dodgers manager Don Mattingly said Turner noticed something was wrong on his inner thigh on Sunday -- and was given medicine, but it didn't heal.

In fact, things got even worse -- so, he was taken to an emergency room where he was treated for an infection ... stemming from the pimple ... and missed the Dodgers game on Tuesday night.

Justin later said the pimple was an ingrown hair that "blew up" and got infected.

Liam Neeson had fans worried when he was spotted over the weekend looking frail and gaunt ... but his rep says the "Taken" star is in good health.

The rep says the 63-year-old actor is "healthy as ever," despite his ghostly appearance in the pic. The rep adds Neeson changed his diet and started doing more exercise about a year ago and credits that for the weight loss.

Plus, the rep says ... it's just an unflattering pic.

Apparently one of Neeson's "particular skills" ... is not always taking a great photo.

Still think wrestling is fake??

WWE superstar John Cena -- star of one of the biggest movies in the country right now -- broke his nose during Monday Night Raw last night ... after Seth Rollins bashed him in the face with a flying knee.

Despite blood dripping from his honker, the "Trainwreck" star continued with the match

WWE doc Steve Daquino says Cena suffered a nasal fraction -- and explained, "He’s got quite a bit of displacement, so we sent him over to the local emergency room so he can be evaluated by the ears, nose and throat doctor who’s on call tonight and see what can be done to properly repair it."

Damn.

By the way, Cena ended up WINNING the match.

Joe Jackson is doing well after a series of medical emergencies ... so well he's cracking jokes in his hospital bed.

A Jackson family rep tells TMZ ... Joe's speech is not impaired and his vision is restored. As we reported, a artery burst behind his eye, causing temporary blindness and possibly triggering a stroke.

Joe says he's aware how close to death he was and is grateful to be alive.

As TMZ first reported, in addition to the stroke ... Jackson suffered three heart attacks while he was hospitalized and his heart actually stopped for 10 seconds. He had a pacemaker implanted.

Joe Jackson suffered 3 heart attacks and just underwent surgery ... TMZ has learned.

The 87-year-old was admitted to a Sao Paulo hospital Sunday after signs of a stroke. Joe lost his vision, and a publicist says it was the result of an artery bursting behind his eye, which triggered the stroke.

Family sources tell TMZ, once in the hospital he suffered 3 heart attacks.

Joe's publicist tells TMZ, in the hospital Joe's heart stopped beating for 10 seconds but he was revived. Joe just had a pacemaker inserted and doctors are now waiting to see if it stabilizes him.

Joe was in Brazil to celebrate his birthday.

Whitney Houston and Bobby Brown's daughter Bobbi Kristina has died at the age of 22.

She passed away outside Atlanta in the hospice care facility where she's been since June 24 ... when her family decided to take her off all meds. As we first reported, a specialist had told them there was no chance of recovery.

The family says Bobbi Kristina was surrounded by family and, "She is finally at peace in the arms of God."

Bobbi Kristina was found submerged in her bathtub on January 31, and police believe she was underwater for anywhere between 2 and 5 minutes. Paramedics were able to resuscitate her, but she was in a medically induced coma and placed on life support.

Ultimately, Pat Houston and Bobby -- co-guardians for Bobbi Kristina -- had to make the decision to withdraw medications. It was a rare moment of agreement for the Browns and Houstons ... who had battled about BK's condition throughout her hospitalization.

TMZ broke the story ... the D.A. has been gearing up for a murder case, and her boyfriend Nick Gordon would be their first person of interest. Police said there were bruises on Bobbi Kristina's face and body after Gordon and a friend, Max Lomas, found her in the tub.

Of course, Whitney died from a drug overdose in 2012 while sitting in a bathtub at the Beverly Hilton Hotel.

Jackson family sources confirm to TMZ, Joe was admitted to the Albert Einstein Hospital in São Paulo after reportedly waking up Sunday feeling dizzy, with no vision.

Joe, who has diabetes, was in the city for his 87th birthday party that was being thrown for him.

These pics were taken hours before the reported stroke.

Nick Cannon is NOT as Ncredible as he thought -- he landed in the hospital on Wednesday after "grinding" on job after job after job.

Cannon posted a pic of himself in a hospital bed, hooked up to a bunch of monitors. He wasn't specific about what's ailing him ... but hinted it was somehow related to exhaustion.

The "America's Got Talent" host said, "I really think I'm a superhero" ... and compared himself to Batman.

Nick's last hospital scare … was in 2012 for kidney failure.

Let's hope the Dark Knight rises from this one soon.
