Nurse!

It hasn't even been a week since Lindsey Vonn broke her arm and underwent emergency surgery ... and she's already got her ass back in the gym.

The Olympic skier hit the exercise bike over the weekend -- while trying to balance a weighted staff with the right arm she snapped during a ski crash on Thursday.

Vonn had a plate and screws put in her arm during surgery -- and now she's rocking a cool black sleeve and brace while it heals up.

#NoDaysOff

Nothing humorous about breaking your humerus ... just ask Lindsey Vonn who cracked her upper arm bone during a bad crash at Thursday's ski practice.

An ex-showrunner over at "Criminal Minds" has a situation on his hands that's less feet-kicking-legs and more teeth-biting-ass ... according to an alleged victim.

Construction worker Timothy Swing tells us he was working this week at the home of former "Criminal Minds" executive producer Edward Bernero when 1 of Ed's 3 Dobermans sank its teeth into his right butt cheek.

Tim says he got a tetanus shot at urgent care, and Edward offered him $3k to make the whole thing go away.

Here's the problem ... Tim says he was poised to rake in almost $13k from the 5 month gig before getting chomped on day 2 ... and Ed never made good on the payment.

Ed has a very different story. He says Tim called the dogs over and started playing with 1 before another jumped on him from behind and scratched him -- that's it. Ed says he felt bad and wanted to help with the bill, until Tim demanded $3k.

Meanwhile, Tim tells us Ed has reached out and offered him some cash ... in return for a promise not to sue.

NBC sent a "goon squad" to manhandle a "Today" show audience member because he's a known Trump supporter and they hated his t-shirt ... according to the guy's new lawsuit.

Mark Gallagher claims NBC security descended on him and roughed him up last month because he was pro-Trump ... according to the docs. He says he was doing nothing wrong at the time -- just chatting 2 ladies and wearing an anti-Clinton shirt.

Gallagher admits he had a motive for being in the "Today" audience ... he believes Bill Clinton is a rapist, and wanted to get some TV time for a shirt with Bill's face and the word "RAPE" on it. He says he was successful doing this the day before on "Good Morning America."

According to the suit ... Gallagher was assaulted by the goons before he even had a chance to take off his sweater and reveal his shirt. He claims he was struck in the back of the head with a security radio and sustained injuries to his neck, lower back, ribs, arms and ankle while being removed ... and has bruises to show for it.

Gallagher is suing NBC Universal for more than $53 million. We reached out to NBC for comment, so far no word back.

"Dancing with the Stars" front-runners Sharna Burgess and Indycar driver James Hinchcliffe got the highest score on last week's episode, but it might've been their swan song ... TMZ has learned.

Our 'DWTS' sources tell us Sharna went down hard during last Monday's dress rehearsal, tumbling on an already banged up knee. She danced with a brace on, but now doctors want her off of the joint for 3-6 weeks. There are only 3 weeks left.

Sharna's definitely out Monday night and possibly the rest of the season.

WARNING: THIS IS GROSS AS HELL

Halloween isn't until Monday but a pro wrestling star is giving you the scariest, most disgusting face you'll see all weekend TODAY ... and we gotta warn you ... it's pretty freakin' gnarly.

The face belongs to Austin Aries, a WWE/NXT star who got his face busted up during a match with Shinsuke Nakamura in Fresno this week when a super kick got a little too real.

According to our friends over at ProWrestlingSheet.com the match had to be stopped while medical professionals attended to Aries' grill ... and give him some stitches.

'NCIS' star Mark Harmon has a dog that attacked a crew member on set, but the dog has a pretty solid defense.

Sources connected with production tell TMZ, Harmon's dog is a 3-year-old pit bull mix that he rescued as a pup. His name is Dave.

Mark frequently brought Dave to the set, which was a dog-friendly environment. Other cast and crew members brought their dogs as well.

We're told a week ago one of the crew members was roughhousing with Dave ... something he did a lot, when the pooch became scared and attacked.

Our sources say the crew member needed 16 stitches to close the wounds, but returned to the set and is fine.

Toni Braxton won't let lupus derail her from tour ... she performed over the weekend with a heart monitor strapped to her chest.

Toni's "The Hits Tour" hit Savannah, Georgia Saturday night where she busted into song with with the monitor in plain view.

We're told doctors urged her to wear it 24/7 to detect chest pain, as well as oncoming heart attacks or strokes.

Toni was hospitalized twice this month ... the result of complications from the autoimmune disease.

She still sounds amazing.

BTW ... Birdman was front and center at Saturday night's concert.

'Honey Boo Boo' star Kaitlyn Cardwell is healthy and recovering after surgery to remove an extra thumb.

Kaitlyn -- Mama June's 4-year-old granddaughter -- was born while the show was still on-air ... and her extra digit became a big topic of conversation. Kaitlyn's mom, Anna, tells us she made the decision to have the thumb removed to thwart medical issues and bullying.

Kaitlyn will wear a cast for 6 weeks ... but it's definitely worth it.

It could have an adverse effect on her cheese ball intake ... just ask Honey Boo Boo.

TMZ Sports has obtained the 911 call made after Paul Millsap's Rolls-Royce collided with a motorcycle this week -- with the witness describing a fiery scene as people tried to help the injured biker.

We broke the story ... the Atlanta Hawks superstar was driving his Rolls on Monday around 6:30 PM when a biker slammed into the front of the vehicle.

A woman called 911 and told the operator, "Oh my gosh, there's fire. It just happened. There's somebody lying on the ground."

"I heard a crash ... and I saw something fly out. I thought it was a piece of a vehicle. It was a person. And the person landed on the sidewalk."

The biker was transported to the hospital with serious injuries. Millsap was not injured.

Cops reportedly blamed the biker for the collision and cited him for failure to maintain his lane.

Toni Braxton can't catch a break -- she's back in the hospital due to complications from lupus, just as she was getting back on the road.

Tommy Ford -- who famously played Tommy on the '90s sitcom "Martin" -- is on life support at an Atlanta hospital after an aneurysm ruptured in his abdomen ... his wife tells TMZ.

Ford has been hospitalized since Sunday and his health has declined ever since.

He is currently on life support and is not expected to make it through the day. Ford's wife, Gina, says the family is still praying for him.

Earlier, Ford's pal, Anthony Anderson, tweeted Ford had died -- but at the time, he was still alive. We're told Anthony had received inaccurate information, and merely tweeted in support of his friend. He's since deleted the tweet.

Tommy starred in all 5 seasons of "Martin" as Martin Lawrence's level-headed best friend, who often played straight man to Martin's crazy antics.

He also appeared on "New York Undercover," "The Jamie Foxx Show" and "The Parkers."

Ford also wrote children's books that promoted drug-free and violence-free lifestyles.

Tim Tebow comforted and prayed over a fan who suffered a seizure after the star's Arizona Fall League game on Tuesday ... and TMZ Sports has footage from the scene.

Tebow -- still in uniform -- was signing post-game autographs for fans when a man named Brandon began to suffer a seizure and collapsed onto the concrete.

Tebow waited with the man for 15 minutes while paramedics rushed over -- with Tim offering words of encouragement until help arrived. In the video, you can hear Tebow say, "Hang in there buddy."

Witnesses at the scene tell us Tebow also prayed over the man -- and even joked around with the guy to keep him in good spirits.

When Tebow was confident the situation was under control he squeezed the man's hand and promised he would be in touch.

The mother of "RuPaul's Drag Race" season 8 winner was injured when a stray bullet pierced her windshield and bloodied her face as she waited in her car in Atlanta.

Bob The Drag Queen confirmed his mom, Martha Anna Caldwell, was taken to a hospital with non-life threatening injuries, saying, "It's a miracle that she's not only alive, but able to go home after a few stitches."

Cops tell us the shooting happened Sunday night when a gunman hopped out of a car and started shooting at another man. Caldwell sat in her car about a block away when one of the rounds struck the windshield ... causing glass and projectile fragments to strike her face.

Bob's pissed about the shooting and railed on what he calls Georgia's "lax gun laws." He pleaded, "This could have been you, or worse this could have been your mother."

The mom from "My Big Fat Greek Wedding" racked up a big fat nursing bill while recovering from a car crash, but never paid up ... so she's been hauled into court.

Lainie Kazan is on the receiving end of a small claims court lawsuit, filed by Dynamic Nursing Services, which claims she stiffed them.

You'll recall ... Lainie was in a bad crash back in April that left her in a neck brace. Dynamic Nursing says it helped nurse her back to health ... then got left hanging to the tune of $2,762.

Lainie has a court date later this month. We reached out to her ... so far no word back.

The army vet who got his arm broken in two by Larry the Cable Guy says it didn't hurt much ... which is remarkable/totally unbelievable.

In case you didn't see ... here's the video.
