Nurse!

Raz-B -- the former B2K singer -- was hospitalized in China yesterday after someone smashed him in the mouth with a glass bottle ... turning his face into a bloody mess.

The 28-year-old R&B star was performing at a nightclub in Zhejiang (birthplace of Qian Xuesen -- the "Father of Chinese Rocketry" ... yay science!).

Raz's rep tells TMZ ... during the performance, he noticed a fistfight in the crowd and went to go break it up -- when someone swung a bottle right into his moneymaker, causing several cuts ... including a deep gash on his lip.

We're told the Chinese police immediately stepped in ... grabbing the attacker AND Raz -- and dragging them both to jail.

Cops quickly released Raz after determining he did nothing wrong. Raz's rep says cops made the bottle thrower fork over roughly $5,000 to pay for Raz's medical expenses.

After the drama at the police station, Raz was finally taken to a hospital, where he underwent a 1-hour surgical procedure to repair the "hole" in his lip. The wound also required 4 stitches.

Raz issued a statement to TMZ saying, "F**k this s**t hurts. I have a f**king hole in my lip. Thank god I made it to the hospital."

John Mellencamp's 2 teenage sons have been charged with felony battery in Bloomington, Indiana after allegedly beating the crap out of a 19-year-old man who was sitting on his own front porch.

According to police, the Mellencamps -- 18-year-old Speck and 19-year-old Hud -- rolled up to the victim's home on July 29, accompanied by a 3rd man ... Ty Smith (son of Indiana University baseball coach Tracy Smith.)

Cops say the trio calmly approached the victim ... and unloaded a ferocious beatdown -- with all 3 men kicking, punching and stomping on the unsuspecting porch-dweller.

Eventually, cops say, the victim's roomates heard the attack -- and raced to the scene to break up the fight ... but the damage was already done.

Cops say the victim suffered facial fractures and cuts that required stitches.

According to the Herald Times, the Mellencamps told cops the attack was a response to an incident that took place at a party earlier that night.

Cops say Speck claims he had been trying to break up a fight between two girls who were arguing over him ... when he was pushed and hit by another man. It's unclear if the "pusher" and the victim are the same person.

FYI -- According to the Herald Times, Hud is a trained boxer.

Officials say the Mellencamps and Smith were all charged with felony battery -- and the Mellencamps have already made arrangements to turn themselves in to police.

This is America, and your medical insurance is a joke -- so says one personal trainer in Hollywood, who's now suing Rod Stewart and his son Sean ... after Sean allegedly attempted to use his med insurance to cover his physical therapy bills.

Randy Rene -- aka The Body Architect -- filed the small claims lawsuit against Sean for $5,440 for services rendered from March to May last year.

Sources close to the Stewarts tell TMZ, Sean hired Randy to help rehabilitate himself following a car accident in which he injured his lower back and shoulder.

When all was said and done, we're told Randy asked Sean for the money, but Sean told Randy to go through his medical insurance instead.

Randy insisted that wouldn't work, and now he's dragging the Stewarts to court. As for why Rod is involved, our best guess is Rod's name is on the insurance and Randy figures suing Rod too is the easiest way to get paid.

It's not the first time Sean was sued by a personal trainer -- back in 2008, some guy named Xavier sued Sean for 4 months of unpaid sessions.

Another HUGE blow for the New England Patriots (and female football fans worldwide) -- 'cause Tom Brady suffered a brutal knee injury during a team scrimmage today ... and it looks bad. Real bad.

Brady -- who was wearing a red "keep your damn hands off me" jersey at the time -- had dropped back to pass when the pocket collapsed on him.... and it appears a lineman fell on his knee.

Brady dropped like a sack of potatoes ... clutching his left knee -- the same knee he destroyed on opening day back in 2008.

Brady was eventually helped off the field and is currently undergoing evaluation.

Paging Tim Tebow ...

3:20 PM PT An MRI on Brady's knee was negative ... according to ESPN.

With "Bachelor" star Gia Allemand still in critical condition ... the reality star's mother and sister shared an emotional embrace outside the Louisiana hospital where Gia's being treated.

Allemand has been hospitalized since Monday, when she was admitted after suffering what her reps are calling a "serious emergency medical event."

So far, the details surrounding the medical emergency are unclear ... but we do know she was alone when the initial incident occurred and she was taken to the hospital by her mother.

TMZ spoke with her mother yesterday -- who wouldn't reveal much ... only telling us, "Gia is very sick." She also asked for her fans to pray for Gia's health.

Soulja Boy copped to acting like a real ass when he got kicked off of a flight -- a la Alec Baldwin -- which reminded us ... our newsroom is also experiencing major ass issues.

It's a whole thing.

ANOTHER legal headache for Chris Brown -- Frank Ocean's cousin has sued the singer, claiming Brown's bodyguard PULVERIZED him during the brawl between the two singers earlier this year ... and Brown egged his thug on.

As we reported, a massive fight broke out between Brown, Ocean, and their entourages over a parking spot outside an L.A. recording studio back in January.

It's unclear who started it, but it got violent, and Frank's cousin Sha'Keir Duarte now says he was one of the worst victims ... thanks to Brown's hired muscle, a bodyguard named "Hood."

Duarte claims Hood punched and kicked the crap out of him, including at least twelve kicks to the body and several to the head, while he lay on the ground.

Duarte claims Brown spurred his bodyguard on -- yelling, "Get that n****r!" -- and even mocked Duarte when it was all over, saying, "You just got your ass beat and it's all on camera."

Duarte says he was permanently disabled following the attack, and now he's suing for unspecified damages.

We reached out to Brown's camp for comment. So far, no word back.

Usher's son is out of the hospital and sporting a huge bandage on his arm ... after nearly drowning last week -- and the kid's already jumping back into some hardcore playing.

5-year-old Usher Raymond V was spotted with his grandma leaving an indoor play center called Mighty Jumps in Atlanta Monday -- a party space filled with moon bounces and flying children -- exactly one week after he had to be rescued when his arm got stuck in a pool drain.

Lil Ush was looking good ... and brought his baby bro along for the fun too.

Doctors for Amanda Bynes got a 30-day extension on her psychiatric hold ironically because she's doing better -- and surprisingly it involves a cascade of tears ... TMZ has learned.

We previously reported the Rx cocktail doctors have concocted to treat what appears to be her schizophrenia seems to be working. We're told in the last few days, Amanda has had a breakthrough.

Specifically, she's showing emotion -- something many schizophrenics don't show at all. We're told Amanda was crying on Wednesday and Thursday night, saying she was scared about the Friday court date -- which she did not attend. Patients who cry are viewed as improving, because sadness is typically not in the playbook.

And we're told Amanda spent Thursday night confiding in one of the nurses about her future, saying she's fine and did not need confinement in a hospital. We're told the doctors believe her ability to form clear thoughts is progress.

It seems a little inconsistent that she's doing better yet doctors sounded the alarm that they needed to keep her for an additional 30 days because she was "gravely disabled." We're told doctors insist they were honest about her condition and feel they can help her with more time.

Es no bueno ... Courteney Cox's Cancun vacation was cut short, when she fell and broke her wrist Saturday -- leaving her no choice but to hightail it back to the states. Ay Caramba.

Our sources tell us ... Courteney was chillin' with friends south of the border when it happened. We're told she somehow slipped and when she tried to break her fall, her wrist snapped. Doctors came to her hotel room and confirmed it was pretty bad.

So much so, the medicos put a cast on the busted limb -- but Courteney wasn't taking any chances and booked a private jet to take her stateside ASAP ... to get treated by her own physicians. It's unclear if surgery will be necessary.

Lo siento.

Chris Brown's seizure Friday was triggered by a giant pain in his ass -- aka the media and lawyers.

TMZ broke the story ... the L.A. City Fire Dept. rushed to a recording studio just after 1 AM after someone called 911 and said CB suffered a seizure​. When EMT's arrived CB refused treatment.

Chris' rep says the seizure was triggered by "intense fatigue and extreme emotional stress, both due to the continued onslaught of unfounded legal matters and the nonstop negativity."

The good news ... the rep says the seizure was nonepileptic -- it's called a NES.

The gold truck Katy Perry commissioned to promote the release of her new album -- Prism -- was just hit by a drunk driver ... TMZ has learned.

The collision occurred 15 minutes ago near a truck stop in Pennsylvania. We're told the driver of a semi-truck slammed into Katy's whip, causing substantial damage to the cab. We're told the semi driver is in the process of being arrested for drunk driving.

Now the good news. The precious cargo is fine ... because Katy wasn't in the truck at the time of the crash. As for the others who were inside, we're told they're ok.

4:55 PM PT -- Law enforcement tells TMZ ... the accident occurred in a Walmart parking lot.

We're told the driver of Katy's truck was inside the Walmart when the collision happened.

The L.A. City Fire Dept. rushed to a Hollywood recording studio early Friday morning, after getting a 911 call that Chris Brown had a seizure ... TMZ has learned.

The call came from Record Plant recording studios in Hollywood at 1:09 AM. When EMTs arrived ... we're told Chris refused treatment and also refused to be transported to the hospital.

We do not know if it was indeed a seizure, but we've learned Chris did suffer from seizures as a child.

Story developing...

The judge in the Amanda Bynes case just granted a temporary conservatorship to her parents.

The judge based his decision in no small part on the findings of an investigator he appointed to evaluate Amanda's mental health.

As we first reported ... Amanda was not in court, because doctors at the psychiatric hospital got a 1-month extension on her psych hold ... because she's "gravely disabled" with mental illness.

Amanda's lawyer told the judge ... she's spoken with the actress several times and Amanda opposes the conservatorship, believing it's not necessary.

The conservatorship not only covers Amanda's personal well-being, it gives her mom the ability to manage her finances. Amanda's $4 million savings have been rapidly depleted, though it's unclear what she's been spending money on. The judge cautioned the parents not to make any significant deals without consulting with Amanda's lawyer.

The judge said he'd like to have some face-to-face time with Amanda, so he can make a firsthand evaluation.

Amanda Bynes has just been placed on an extended, 30-day psychiatric hold ... and the people responsible for making that happen were not her parents -- they were her doctors ... TMZ has learned.

Sources tell us ... doctors at the psychiatric hospital where Amanda has been held for the last 2 weeks determined she was not well enough to leave the hospital to attend today's hearing -- where her parents are trying to win a temporary conservatorship.

We're told doctors went to a judge who traveled to the hospital to conduct an emergency hearing. The judge granted the doctors' request, and extended Amanda's psych hold for 30 days.

According to the law, doctors can only get such an order if the patient is "gravely disabled as a result of a mental disorder."

Amanda's parents will still pursue the temporary conservatorship, we've learned, because it will stay in effect until Sept. 30th. And the conservatorship would allow her parents to control Amanda's finances.

Usher's ex-wife is clearly trying to prove a point ... she's a caring mother who deserves custody of their sons -- after the eldest nearly drowned this week -- and this photo tells the story.

Tameka Raymond posted the photo today, the first pic of 5-year-old Usher Raymond V since the horrific accident on Monday ... and it paints a picture of motherly love and protection. Tameka's arms are wrapped around her son, and he's surrounded by get-well-soon balloons.

It's a subtle dig at Usher ... who is noticeably absent.
