DUI

If Snooki and new hubby Jionni LaValle left their wedding reception in a car with tin cans attached, it's a safe bet he didn't drive ... because we found he was on the heels of a drunk driving arrest.

Jionni spent the first weekday as a married man in court, where he copped a plea in his criminal case. He was arrested August 7 on Interstate 80 in Totowa, NJ at 3:30 AM after cops noticed him driving erratically.

Jionni pled guilty to DUI on Monday and had 2 other charges -- unsafe lane change and careless driving -- dismissed. His license was revoked for 3 months and he has to attend a drug and alcohol education class.

Snooki can relate ... she was arrested in 2010 for public drunkenness on the Jersey Shore.

Buddy Valastro put his drunk driving case to bed by making a surprise trip to the courthouse ... to plead guilty to driving while drunk.

As a result of the plea, the "Cake Boss" star's license will be suspended for three months, and he has to enter a drunk driving program. He also got a $300 fine.

Valastro says he told the judge he only had one drink before getting pulled over -- but added he'd learned his lesson ... "If you have even one drink you shouldn't drive."

He wasn't scheduled to be in court until February, but after today's hearing he tweeted he went in early because ... "I wanted to make this right."

As TMZ first reported, Valastro was arrested on November 13 after cops noticed the TLC star's 2014 yellow Corvette weaving on 10th Ave in Manhattan.

Kaplan flunked the field sobriety test and was taken to the West Hollywood Sheriff's substation and booked on DUI.

The cast of "Party Down South" has a love for booze in mass quantities ... and they've racked up another in a long list of DUIs.

PDS star Josh Murray was pulled over in Rankin County, Mississippi early Saturday. He flunked the field sobriety test and went to jail for DUI and driving with a suspended license.

It's the second time Josh has been popped for DUI. He faces jail time, and license suspension for 2 years.

PDS has a rich history of alcohol-related hijinks. Mattie Breaux was busted for DUI earlier this year, Ryan Richards bonged an entire bottle of Jägermeister, and Lyle Boudreaux allegedly stole a credit card so he could keep his binge on during Mardi Gras.

The good news ... at least nobody pissed themselves this time.

Buddy Valastro -- the star of "Cake Boss" -- was arrested early Thursday AM for driving while intoxicated ... TMZ has learned.

Law enforcement tells TMZ ... cops noticed the TLC star's 2014 yellow Corvette weaving on 10th Ave in Manhattan. They cops lit 'em up, pulled Buddy over and smelled a strong odor of alcohol.

Buddy will go before a judge who will set bail -- probably this morning.

"The Voice" contestant Delvin Choice is influenced by R&B legend Usher, and cops say he's also influenced by drugs or alcohol ... because Choice got busted for DUI.

Law enforcement tells TMZ ... it's Choice's first offense. He was taken to jail ... and freed after paying $1229.50 bail.

Choice's father -- who's a Baptist pastor -- told the media, "We all make mistakes in life. We learn from our mistakes."

It's all about choices.

Officials have finally released dash cam footage from the night Indianapolis Colts owner Jim Irsay was arrested for DUI ... and the guy was a complete mess.

The 55-year-old was popped just before midnight on March 16th ... and as you can see in the clip, he could barely keep his balance as he stumbled out of the car.

Cops say Irsay had multiple painkillers in his system, including oxycodone and hydrocodone.

Irsay eventually pled guilty to one misdemeanor count of operating a vehicle while intoxicated -- and was sentenced to 1 year probation.

The NFL also suspended Irsay for 6 games ... and fined him $500k.

Justin Bieber knows trouble and apparently likes it ... because he's back with Lil Twist.

Biebs and Twist made a turbulent exit from Playhouse in Hollywood Thursday night. There's good reason why Bieber was behind the wheel ... Twist has already racked up a DUI arrest while driving one of Justin's cars.

Justin's people almost strong-armed the singer into cutting ties with Twist after a series of incidents ... including Twist speeding on an L.A. Freeway which ended with someone getting killed -- when a photog was struck by a passing motorist.

Cute pigtails ain't gonna get Tami Erin outta this one ... the actress who played "Pippi Longstocking" has been ordered back to school as part of her DUI sentence.

Erin will be on probation for 3 years, and has to perform 240 hours of community service. Sorry, Erin ... making another sex tape will not count toward that number.

Phelps added, "Swimming is a major part of my life, but right now I need to focus my attention on me as an individual, and do the necessary work to learn from this experience and make better decisions in the future."

Phelps did not say whether he will be receiving treatment for gambling as well -- but it's no secret the guy has a penchant for playing cards.

Amanda Bynes was out of control at her fashion school ... showing up high and offering fellow students money to do her homework ... and we're told it got so bad she was kicked out.

Student Rachel Loritz tells TMZ ... Amanda often ditched classes ... but even when she showed up, she was clearly high, and not good at hiding it ... she almost always wore sunglasses and laughed out loud at inappropriate times.

We're told the pendulum would often swing and she would then get in "horrendous arguments."

Rachel says ... Amanda paid fellow students to do her homework ... and some took her up on it. Rachel says she rejected Amanda's offer.

We're told Amanda was caught cheating off someone during a test ... and when she was called out she threw a fit.

"But he will become smarter from this. Luckily he did not hurt himself or someone else."
