Nurse!

This is NOT your grandfather's cane -- unless your grandfather is super pervy or Axl Rose.

Rose has been hobbling around England this week using a walking stick, but little did we know what's under his hand is the most badass, rock 'n' roll senior citizen accessory ever.

The stick's sterling silver handle features a naked couple doing, um ... what naked couples do.

Axl's slowly recovering from his broken foot, but once he's fully healed -- he's gotta keep this thing handy.

Limping's never been so pimpin'!

Scary moment for Floyd Mayweather Sr. ... who was hospitalized in Vegas early this morning ... but appears to be okay now, TMZ Sports has learned.

We've confirmed ... emergency personnel responded to a call around 7:30 AM to a coffee shop. The 63-year-old was loaded into an ambulance and transported to a nearby hospital for treatment.

A rep for the Mayweather camp tells us Floyd Sr. was simply dehydrated and is doing much better now. We're told he's not expected to be held overnight.

Floyd Sr. was a pretty good boxer in his own right -- and fought Sugar Ray Leonard in 1978 (he lost though). He eventually became one of the biggest trainers in boxing.

WARNING: If you love your five digits, this photo will be a little hard to look at.

NFL player Charles Tillman might've just won "gross-out moment of the week" (although it's only Thursday) sharing a picture of his pinky finger on social media sure to make you rethink breakfast.

Dude's been in the NFL for like 12 years so there's no telling how he injured the finger -- but we do know one thing ... they ain't supposed to bend that way.

Australian rules football legend Richie Vandenberg got hit in the face with a glass at a NY bar early Thursday morning ... but despite his injuries, he refused medical attention, TMZ Sports has learned.

Here's what we know ... 39-year-old Vandenberg -- who captained the Hawthorn Football Club from '05 to '07 -- was partying at the Catch bar in NYC with a lady friend when someone came up to her and asked her to dance.

We're told she refused... and Richie came over to help get her point across, when the dude smashed Richie in the face.

Police were called and the suspect -- a 32-year-old man -- was arrested. Cops say Richie suffered a laceration to the forehead but didn't want to go to the hospital.

Australian rules football players are tough.

BTW, Vandenberg was a stud during his time with the squad ... and was hailed as turning Hawthorn into one of the most dominant clubs in the AFL.

A Dallas high school employee claims Deion Sanders' teenage son brutally attacked him on school grounds ... beating him so badly, he needed spinal surgery ... this according to court docs obtained by TMZ Sports.

Richard Simmons apparently was not released from the hospital as his people said, because it appears he was beating a hasty retreat Monday night from Cedars-Sinai Medical Center.

We're pretty sure it's Richard in the back seat -- sporting a beard -- with his longtime housekeeper/friend riding shotgun.

TMZ broke the story ... the housekeeper called 911 Friday just before midnight, saying Simmons was incoherent. Paramedics took him to Cedars, but his people claimed the fitness guru was released the following day.

Richard Simmons' people claimed he was in the hospital for less than 24 hours, but that doesn't seem to be the case, because his housekeeper made several trips to Cedars-Sinai ... days after he was admitted.

The housekeeper (above) made 2 trips to Cedars Monday. TMZ broke the story ... the housekeeper called 911 just before midnight Friday after Richard became incoherent. He was taken to Cedars, but the housekeeper and his other confidantes claimed he was out by Saturday afternoon.

A post on Simmons' Facebook account stated he suffered from dehydration, but 3 days in it looks like he never checked out of the hospital.

MMA fighter Kimbo Slice was hospitalized in Florida earlier Monday ... and multiple sources tell TMZ Sports the situation does not look good.

Law enforcement sources tell us ... Slice was admitted to a hospital near his home in Coral Springs, FL.

Police are currently at his home gathering information from family members.

Kimbo -- real name Kevin Ferguson -- last fought at Bellator 149 back in February and defeated Dada 5000 -- but the victory was overturned when Slice tested positive for a banned steroid.

Back in 2003, Slice became an Internet sensation for his backyard fighting videos -- destroying several opponents in unsanctioned street fights. He later signed a deal to fight in the UFC.

TMZ Sports has obtained footage from outside the Aqib Talib shooting incident -- in which you can hear at least 4 gunshots fired.

A Disney roller coaster ride became unhinged and a visitor, who was on the sidelines minding her own business, got knocked out by a bolt out of the sky ... literally.

Tatjana Goodall claims in a new lawsuit she was sitting on a park bench enjoying a cool drink when an errant bolt that had just flown off the California Screamin' roller coaster nailed her in the head, knocking her off the bench and rendering her unconscious.

Goodall claims she began vomiting, but the nurse at Disney California Adventure assured her the only worrisome sign would be if it was projectile vomiting, and she had the regular kind.

Goodall says she was diagnosed with traumatic brain injury, and she says there's permanent damage.

According to the lawsuit, the ride was shut down immediately after the incident.

SoulCycle's crappy instructors and faulty bikes are to blame for a catastrophic ankle injury ... so claims a very disgruntled customer.

Carmen Farias claims in a new lawsuit she showed up to spin class in 2014 and, since she was a newbie, she expected someone would show her how to use the bikes. Farias says she started riding but quickly tired and the instructor barked, "We don't take breaks."

Farias says she was so embarrassed she soldiered on, as her feet were locked to the pedals. She says she became so fatigued she fell off the bike with her feet still strapped in ... but the momentum of the fly wheel kept the pedals turning, and each rotation caused ankle dislocation.

She blames the bikes and lack of instruction for what she claims are catastrophic ankle injuries.

4:00 PM PT -- Mokrani doesn't know what the hell Chris is talking about ... he tells us he was NOT working security at the club.

8:55 AM PT - Chris Brown posted on social media and said Mokrani was a security guard who assaulted him and tried to kick him out, so his team "handled the situation accordingly."

Chris Brown exploded in anger and stomped on a man's head during a concert ... and the victim is now gunning for some justice.

Malek Mokrani attended a Brown concert in Cannes on May 18 ... it's clear a fight erupted and something clearly upset Chris, because you see his shoe turn into a weapon.

It's unclear if Mokrani was involved in the fight or just collateral damage.

He tells us he went to the hospital with neck and head pain and plans on filing a police report.

We reached out to Brown's rep. So far no word back.

Laila Ali is thanking the fans for the love and support after her father was hospitalized this week ... but did not provide any health updates.

Andrew Kornfeld, the man who called 911 when Prince died, firmly believes he could have saved the singer with the backpack full of opioids he had at Paisley Park that morning.

The ME's report revelation that Prince died from a self-administered dose of Fentanyl ... seems to acquit Kornfeld and his father, Dr. Howard Kornfeld, of any involvement in the death. Andrew was delivering an opioid called Buprenorphine to treat Prince's addiction to Percocet. He insists Prince never took the drug.

Now Kornfeld is singing the praises of the synthetic opiate, saying it should be more accessible to addiction patients everywhere. Kornfeld tells CNN, he believes part of Prince's problem was that Buprenorphine is very difficult to get in Minnesota.

Muhammad Ali has been hospitalized for a respiratory issue ... and he's currently in fair condition, this according to the boxer's spokesperson.
