Drugs & Alcohol

David Cassidy seems to have fallen off the wagon -- and almost off the stage -- in what appears to be a drunken performance this weekend.

The former teen idol was playing a gig in Agoura (near L.A.) Saturday night, where he looked incredibly intoxicated throughout the show ... ultimately leading to a hard fall over a monitor.

David slurs through various songs and and takes long pauses, often forgetting lyrics. He said on stage that Sunday night is his final concert ever due to health reasons ... and he's retiring.

David has been to rehab several times and has struggled with alcoholism.

We've reached out to Cassidy's rep ... so far, no word back.

Vince Young straight threw in the towel during his '16 drunk driving arrest -- refusing to complete field sobriety tests after getting frustrated with the cop ... and ultimately saying, "Are we going to jail or not?"

TMZ Sports obtained the arrest video from January 24, 2016 which shows Young being pulled over in Austin, Texas, after the officer says he was driving erratically in his white truck.

Young starts off being nice and cooperative ... but gets increasingly frustrated with the DWI investigation process.

He refuses to get out of his car until the officer orders him out.

He gets sick of the eye test and tells the officer he won't comply.

At one point he says, "What's the problem? Are we going to jail or not?"

The officer finally gets fed up when Young refuses a breath test and arrests the ex-NFL star.

Plies was arrested for DUI by some pretty stonefaced cops, because it's borderline remarkable they didn't lose it as they gazed into the horrified eyes of one Kevin McCallister.

TMZ obtained the dash cam footage of the Florida rapper's January arrest ... the main attraction is definitely the "Home Alone" tee.

You hear the officer tell Plies he was driving the wrong way down a one-way street. Plies was cooperative ... calmly answering questions about a gun in the car.

Lauryn Hill didn't skip a beat as she was closing out her Nashville show ... even though a dude was getting booted right in front of the stage.

Hill was mid-song at Ryman Auditorium Thursday when a disturbance went down in the crowd. It's hard to tell exactly what happens in the video, but witnesses tell us a drunk guy was harassing a woman ... who was eventually lifted to the safety of the stage by security.

Cops say they got a call for a scuffle between two people and arrested a man for public intoxication, resisting arrest, criminal trespass and disorderly conduct ... but it's unclear if it's from the same incident as the video.

Charles Oakley says he DID drink alcohol before things exploded at Madison Square Garden Wednesday night ... but insists he was not drinking INSIDE the arena.

The Knicks legend sat down with FOX 5 in NYC and told the reporter before the interview that he believed the team was trying to portray him as a guy who was drunk and out of control at the time of the incident.

The reporter followed up on the claim when the camera was rolling ... and Oakley admitted to having "a couple drinks" before the game.

Steve Francis is the new Lindsay Lohan -- 'cause he was just ordered to wear an alcohol-monitoring ankle bracelet after violating the terms of his bond.

The trouble all stems from the ex-NBA star's drunk driving arrest back in November -- when cops say he was driving around Houston while hammered and in possession of weed.

At the time, Francis was released on bond -- and was ordered to NOT drink a drop of alcohol. He was also ordered to put a breathalyzer device in his car.

But, officials say he blew off his blowing obligations and didn't use the device -- a violation of the terms of his bond.

He appeared in court Thursday, where the judge dropped the hammer by ordering him to wear a SCRAM bracelet -- which constantly monitors alcohol consumption. It also has a GPS tracking device (he's not allowed to leave Texas).

If Francis doesn't get his new accessory by tomorrow, the judge says she will issue a warrant for his arrest.

The best Super Bowl party went down in Holmby Hills -- where Diddy threw a rager at his mansion ... complete with huge stars, huge TVs and TONS of booze!

Chris Brown, Kourtney Kardashian, Chris Rock, Russell Simmons, Miguel and many, many more rolled up to Diddy's mansion for the shindig and turned all the way up!

Diddy was toasting everyone with his Ciroc vodka and DeLeon tequila -- Shots! Shots! Shots!

The rap mogul was rockin' a fur coat and a pimp cane -- but it wasn't just for looks -- he recently underwent knee surgery.

The Houston Police Department is expecting the worst outside the Super Bowl and is ready to combat a wave of Prez Trump protesters making noise about disrupting the game.

Our law enforcement sources say officers, in uniform and undercover, will monitor crowds outside NRG Stadium. We're told several online groups have popped up in recent days organizing protests -- some anti-Trump, some for Black Lives Matter, Standing Rock and refugees.

HPD has plenty of backup, having borrowed cops from around the country. As usual for the Super Bowl ... we're told SWAT will be posted nearby if protests turn into riots and get out of hand.

Lady Gaga is about to one-up the singer who turned lemons into lemonade by turning grapes into delicious wine.

Gaga plans to launch her own brand of wine called "Grigio Girls" ... named after a bonus track on her 2016 album, Joanne. Her company filed paperwork to produce wine, wine coolers, wine cocktails and wine punches with the name.

We're guessing Pinot Grigio will be the flagship product.

"Grigio Girls" is a song inspired by Gaga's friend, Sonja, who has cancer -- it's about how Gaga and her girlfriends would get together, pop open a bottle and cry for her. So ... their own brand of wine seems like a perfect tribute.

Lady Gaga's not totally new to the food and drink biz, though -- her parents own an Italian restaurant in NYC called Joanne Trattoria.

WWE legend Tammy Sytch says she has "tremendous guilt feelings" about the death of her good friend, Chyna ... admitting she failed to get her the help she needed when she saw Chyna struggling.

Sytch -- aka Sunny -- was on her way to court-ordered rehab this week when she told us Chyna's death has been on her mind for months. The two were very close and would FaceTime every night.

The Hall of Famer says she recognized Chyna was going down a bad path and tried to convince her to go to rehab -- but she refused, and died while Sytch was seeking treatment for herself.

Obviously, Chyna's death isn't Tammy's fault ... but Sytch says she wishes she could've gotten her friend to see the light. Chyna passed away in April after overdosing on Rx pills and booze.

As for Tammy ... her next stop is another stint in rehab to combat her ongoing alcohol issues -- and she says she's receiving the full support of the WWE.

Newly uncovered text messages allegedly sent by ex-Baylor coach Art Briles show how poorly he handled situations where his football players were involved with drugs, guns and even an incident where a player exposed himself to a woman at a spa.

Mischa Barton was not in her right mind after she says someone spiked her drink with GHB ... and video of the incident shows it was a dire situation.

The video -- shot Thursday before she voluntarily went to the hospital -- shows the 31-year-old former 'O.C.' star rambling, then losing her grip on her fence and falling to the ground.

Barton told People this was all a reaction to the so-called "date rape" drug -- which someone dropped in her drink while she was celebrating her birthday Wednesday night.

Indianapolis Colts running back Robert Turbin is officially off the hook in his marijuana case ... despite the fact he seemed to take responsibility for the incident on Twitter.

Turbin was pulled over Utah on July 8 for running a stop sign and during the stop, cops found "a rolled joint-type thing" in his car. He was cited for marijuana possession and ordered to appear in court.

He later tweeted, "My mistake. Won't happen again."

But now, TMZ Sports has learned prosecutors threw out the case on "evidentiary grounds" -- and a rep for the Logan City Justice Court tells us there was evidence that shows Turbin might not be guilty.

Bottom line ... case closed. Turbin's in the clear.

Ex-NBA player Charles Shackleford -- who played for the Nets, 76ers and Timberwolves in the '90s -- was found dead in his hometown of Kinston, North Carolina ... police confirm.

Shackleford was 50.

Cops tell TMZ Sports, "We can confirm Charles Shackleford was found deceased in Kinston this morning."

"The cause of death has not been determined. This incident is still under investigation. More information will be released as it becomes available."

Shackleford was a stud in college at N.C. State in the '80s -- but was more infamous for a post-game quote in which he attempted to describe his shooting talents.

"I can shoot with my left hand, I can shoot with my right hand, I'm amphibious."

Shackleford got into a bunch of legal trouble after his NBA career -- and was arrested in 2010 for selling drugs to an undercover police officer.

Migos' album release party at a NYC strip club was a win-win-win for the group, the club and all the strippers!

The shindig went down this week at ACES in Long Island City, NY. We're told the packed night brought in more than $100k in profit, and $20k of that was the stacks Migos dropped on the dancers and booze.

If you're wondering what a bad and boujee booze order looks like ... our strip club sources tell us the fellas pounded 3 bottles of Ace of Spades, 4 bottles of Ciroc, 2 bottles of Hennessy and 2 bottles of 1942 Don Julio.

Stitches is sending God Bless Yous to the cops who hauled him off to jail.

The rapper seems to think the police have it out for him just because of his "success." He starts off pretty pissed in this video, but does a 180 about his Wednesday night arrest for guns and drugs.

Kisses from Stitches? Miami PD must be thrilled.
