Nurse!

The Edge still can't find what he's looking for ... in this case, the rest of the stage.

U2 opened up its "Innocence + Experience" world tour Thursday in Vancouver. As the band played its iconic hit, "I Still Haven't Found What I'm Looking For" ... Edge went flying offstage.

After the show he posted he was fine, writing, "Didn't see the edge, I'm ok!! #U2ieTour." Looks like his arm is badly scraped.

The band is already operating at less than 100% -- Bono suffered a terrible bike accident in NYC last November that required two surgeries.

The wife of former UFC fighter Corey Hill tells TMZ Sports ... her husband is still alive and fighting for his life ... despite statements from family, friends and the UFC saying he passed away this morning.

Hill's close friends and family members had told the media earlier today that Hill died after a bout with pneumonia.

But Lauran Hill says Corey is "resting and still alive" and they're praying he makes a full recovery.

"My husband is a strong fighter. Please everyone pray for him."

Big Ang hit the Big Apple Wednesday night … a month and some change since having a nasty cancerous tumor removed from her throat.

Despite the intense surgery ... it's hard to see any scar, so it looks like the docs did good by the ‘Mob Wives’ star.

Ang gave our camera guy the low down on her road to cancer-freedom. It also looks like she's trying a new diet -- Ang posted a pic of herself hanging at Wild, a gluten-free Italian joint.

Big Ang ain't afraid of change.

Suge Knight has given doctors a piece of his mind ... refusing to have a bullet fragment removed that’s been lodged in his head for the past 19 years ... a bullet intended for Tupac Shakur.

Rewind to 1996 … Knight infamously drove the car carrying Tupac the night of the rap legend’s drive-by murder off the Las Vegas strip.

One of the bullets missed Tupac but grazed Suge's head; a fragment lodged in his skull, and was never removed.

Here's the problem. Suge's in bad shape as he lingers in a jail cell, and doctors want to perform an MRI so they can figure out why he keeps passing out. But the bullet fragment causes interference with the machine, so doctors want to remove it.

Suge’s attorney, Matthew Fletcher, tells us Knight thinks he'll die if doctors start screwing with his head and try to remove the fragment, especially given his fragile state.

Aside from medical concerns, you gotta admit ... how cool is it to have a Tupac bullet in your head?

Captain Jack Sparrow got carried away with the smuggling -- Johnny Depp's 2 Yorkshire Terrier pups have a death sentence hanging over their heads because Depp allegedly snuck them into Australia.

Australian officials say Johnny and Amber Heard failed to declare Boo and Pistol when they arrived on a private jet last month. Under Australian law the dogs are supposed to be quarantined for a minimum of 10 days ... just to make sure they're not carrying any foreign diseases into the fragile ecosystem.

If Johnny, or more accurately ... Boo and Pistol don't hightail it out of Oz by Saturday -- the country's Agriculture minister says they will be put down.

A rep for Johnny -- who's down there shooting the 5th 'Pirates' flick -- told the AP the dogs are under a "home quarantine" ... but wasn't more specific than that.

Mariah Carey's tour is already rocky and it's only been a week ... she's just cancelled Wednesday night's Vegas show.

Our Mariah sources say the singer has bronchitis and her doctors have advised her not to use her voice.

We're told so far only Wednesday night's show is cancelled and she has a couple of days off until the next scheduled performance. But it's uncertain she'll be able to perform.

The cancellation came at the last minute. People have flown in for the show and we're told many have arrived at the venue, where they saw the sign that says "Tonight's performance has been cancelled and will not be rescheduled."

She's one of the most decorated Olympic athletes in United States history .. but Amy Van Dyken says the biggest accomplishment of her life is STANDING again ... after severing her spinal cord last year.

Her story is incredible -- Van Dyken was seriously injured in a brutal ATV wreck back in 2014 ... but she's been fighting like hell to regain full use of her legs -- and this week, made some serious progress.

In fact, Amy appeared on "TMZ Hollywood Sports" on Wednesday and told us that battling back to stand on her own was "absolutely" the biggest accomplishment of her life ... even greater than winning her 6 gold medals.

You gotta watch the video -- Amy says she's laser focused on walking on her own one day ... and given the progress she's made so far, you'd have to be crazy to doubt her.

Presidential candidate Dr. Ben Carson does not lack wisdom, but incisors are a different story.

The Republican hopeful -- who made a name for himself in 1987 as the first neurosurgeon to separate twins conjoined at the head -- was stumping at Tommy's Country Ham House in Greenville, South Carolina where he chowed down on scrambled eggs, grits and ham biscuits when he noticed a bonus on his plate ... his front tooth had fallen out.

The good doc stared into his plate, thought for a second then discretely placed the errant chomper into his shirt pocket.

Carson then stood up and delivered an impassioned speech ... with a hint of whistle.

Olympic swimmer Amy Van Dyken just reached another milestone on her miraculous road to recovery -- she's now able to stand and support her own weight.

Van Dyken posted a video of her latest accomplishment and said, "I'm starting to get this standing thing down! #amysarmy #werk #IllBeWalkingSoon #GettingFittedForBracesNextWeek"

Van Dyken -- who won four Olympic gold medals in 1996 and two more in 2000 -- severed her spine in an ATV crash in June 2014. Since then she has posted video of her progress ... taking her first steps with the help of an exoskeleton ... and a few months later, pedaling a bike on her own.

Miles Teller did not rescue a pregnant woman caught in a Miami riptide -- it was the pregnant woman who gave Miles a heads up ... jaws was lurking in the water.

Model Keleigh Sperry, who was spending a fun-filled day in the sun with the "Whiplash" star, says the pregnant woman came up to them "freaking out" that a shark was in the water. And the woman had a toddler on her back to boot.

Nonetheless, you can see from the pic Miles helped the very pregnant lady out of the water and harm's way.

He's awesome, and the shark didn't bite anyone.

Forget superpowers, Miles Teller's hero game is on fleek ... this weekend the "Fantastic Four" star and his GF swooped in and rescued a pregnant woman caught in a potentially deadly riptide in Miami.

It's pretty amazing ... Teller and GF Keleigh Sperry's romantic beach day was interrupted when an extremely pregnant woman began screaming for help just offshore ... without hesitation the two darted into action and tag-teamed a rescue effort that saved the woman's life.

Once on shore, the two made double sure the woman was alright and then parted ways.

Looks like playing Reed Richards definitely rubbed off on him ... as for the romantic beach day, if saving lives doesn't get you in the mood ... nothin' will.

Pat Houston is now sharing the controls with Bobby Brown on what to do with Bobbi Kristina ... and it appears a rift may be brewing, because a Houston family member strongly indicates she does not want to use heroic measure to save Bobbi.

As TMZ reported ... a judge made Bobby and Pat co-guardians a few days ago, which gives them joint responsibility for Bobbi Kristina's care. As we first reported, Bobbi Kristina is suffering from irreversible brain damage and the prospects of getting better are slim to none, barring a miracle.

Pat says she and Bobby are working as a family to make the right decisions, but there seems to be a clear division. Cissy told "Entertainment Tonight," "She's not gone yet, but you know, whatever the Lord decides, I'm ready for her ... I have nothing to do with that. That's His job."

Bobby, on the other hand, has made it clear he will do whatever it takes to keep his daughter alive, including using heroic measures if she begins to slip away. Some member of the Houston family have strongly indicated they are not inclined to use such measures.

If Bobbi Kristina's condition begins to deteriorate and if Pat and Bobby can't reach an agreement, it will probably be left in the hands of a judge to decide the fate of Whitney Houston's daughter.

The 2 families have been largely at odds since Bobbi Kristina entered the hospital.

A little boy was hurt when he was manhandled by Pluto at Disneyland ... and his mom says theme park officials tried to keep the incident on the QT.

It happened Thursday in Toontown, when 8-year-old Ethan walked up to Pluto to give him a hug. The Plutonic cast member obliged, but when you watch the video in slow mo it appears he hyperextends Ethan's back. The boy begins to cry almost immediately, saying he's in pain.

Ethan and his mom Laurie were told to go to the first aid station, but they didn't want to walk the distance because Ethan was hurting. A nurse came over, examined Ethan and told Laurie he was fine.

Ethan said he felt sick and wanted to go home, so Laurie asked for a wheelchair so her son didn't have to walk to the car. Laurie says the employees refused her request and said she could take Ethan in a stroller. Laurie believes the park didn't want to highlight the injury with a wheelchair.

The boy tried but couldn't tolerate the stroller -- so Laurie demanded medical attention and paramedics took Ethan to the hospital for x-rays. Doctors believe Ethan has severe muscle strain.

Laurie tells us, a Disney rep showed up at the hospital, apologized for the way things were handled, offered to pay the hospital bill, and brought them El Pollo Loco for dinner.

Laurie says she was also told Pluto was disciplined for roughing up Ethan.

Whitney Houston's family and Bobby Brown will now be forced to work together -- Bobby and Pat Houston have been appointed co-guardians of Bobbi Kristina.

The court ruling means Whitney's sister-in-law and Bobby will now share responsibility for 22-year-old Bobbi Kristina's medical care. Bobby filed a petition last month to become her legal guardian.

The court also appointed an attorney -- Bedelia Hargrove -- as conservator, and she will control all financial and legal matters for Bobbi Kristina ... who is now breathing on her own. Whitney's family points out she's suffered "global and irreversible brain damage."

We got video of Pat and Cissy Houston leaving the DeKalb Co. courthouse after Thursday's hearing, and Pat told us, "It was a good day."

Manny Pacquiao says his shoulder surgery was a rousing success -- and just posted his first post-op selfie to prove it.

Pacman went under the knife in L.A. Wednesday night to repair a torn rotator cuff in his right shoulder -- an injury that he didn't properly disclose to officials before the big Mayweather fight.

Of course, Manny thanked God for the procedure ... and his wife ... and his world famous doctor ... saying, "Thank you to my Dr. Neal Ellatrache and his group for taking care of me. God is great!"

One thing we noticed in the pic ... not a single mark on his face.

Shaq might be on the 15-day DL after taking a (hilarious) spill on the set of "Inside the NBA" last night ... that's according to co-host Kenny Smith who says the big man's big fall has left him a little gimpy.

Kenny was at LAX this morning when we HAD to ask him about everything regarding the tumble heard 'round the galaxy ... most notably how the Diesel is moving following the gravitational smackdown.

Bad news for Shaq ... seems he was a little banged up after all.

Get well Diesel.
