DUI

The guy who smashed into Jennifer Lopez's brand new Rolls-Royce was bombed -- nearly twice the legal limit -- and now could face time behind bars ... according to prosecutors.

The L.A. County D.A.'s office is charging Robert John Reitz with two misdemeanor counts of DUI for the September rear-ender on Pacific Coast Highway -- and they say his blood alcohol content was an astonishing .15.

You'll recall JLo and her pal Leah Remini were cruising in Jennifer's Rolls at the time of the accident. They posted a pic of themselves looking fabulous ... just seconds before Reitz hit them and fled the scene.

Reitz faces 6 months in jail and a $1,000 fine if convicted.

10:50 AM PT -- Phelps must abstain from booze, and can't abusively use drugs. He'll have to submit to drug and alcohol testing ...at the discretion of his probation officer ... and attend self-help group meetings.

He will be allowed to travel out of state for training sessions.

Michael Phelps showed up to a Baltimore court Friday morning where he pled guilty to driving under the influence.

Phelps was given a one-year suspended sentence and 18 months probation ... meaning if he screws up in the next 18 months, he goes behind bars for a year.

The Olympic hero arrived with his mom, sister and girlfriend -- Miss California 2010 Nicole Johnson.

We broke the story... Phelps was busted on September 30 at 1:40 AM for DUI. His B.A.C. was nearly twice the legal limit.

He checked himself into rehab following the arrest.

Keyshia Cole faces jail time over a DUI she got a decade ago ... and no one would have been the wiser had she not flown into a jealous rage in Birdman's condo.

Cole was in a L.A. County court this week ... trying to explain to a judge that a very old arrest warrant was a gigantic mistake. The warrant was issued in 2004, because Keyshia failed to submit proof to the judge that she completed her alcohol ed class after a 2002 DUI conviction.

Keyshia's lawyer tried explaining the singer completed the course, but the judge was unmoved. There was no paperwork to prove it, so the judge indicated he'd throw her in jail for 30 days.

But the judge also showed some mercy, telling Keyshia's lawyer he would let her skate if they could submit proof she finished the classes. A hearing is set for February.

Now here's the bitch. Authorities had no idea there was a warrant and probably wouldn't know, but when Keyshia was arrested in September for assaulting a woman in Birdman's condo, cops did a warrant check and ... bingo.

Boyfriends cause such trouble.

Billy Unger from the Disney show "Lab Rats" ... plead no contest to a lesser charge in his DUI case -- keeping him out of jail as long as he toes the line.

As TMZ first reported -- Unger was nailed for speeding in Malibu back in June, but the then 18-yr-old also blew a .08 ... which is the legal limit if you're 21. Under Cali law minors behind the wheel can't have a drop of alcohol in their system.

Prosecutors offered Unger a plea deal -- dropping DUI and speeding charges ... and he plead no contest to wet reckless. It's a lesser charge usually offered to first time DUI offenders like Billy who were at the legal limit.

Unger got a fine, 2 years probation, and has to complete alcohol education programs.

Most people spend a fortune on wedding photogs, but Xzibit got his for free, courtesy of the police who took his mug shot after he got arrested for DUI immediately after his reception.

Xzibit tied the knot Saturday night near Laguna Beach, CA. He and his bride, Krista Joiner, partied hard at the St. Regis Monarch Beach. After getting pelted with rice early Sunday ... he left, presumably with her.

But the coitus got interrupted in Laguna, when cops pulled Xzibit over for speeding. He reeked of booze so cops cuffed him and took him to the station.

It's fitting ... Xzibit was associated with the group, The Alkaholiks.

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.

The lawyer repping child molester Stephen Collins in his divorce is going to be jumping from courtroom to courtroom, because TMZ has learned he was busted for DUI Friday night.

Mark Vincent Kaplan -- who became famous repping Kevin Federline in his contentious divorce from Britney Spears -- was popped on the Sunset Strip just before midnight.

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.

We're told Buddy flunked multiple field sobriety tests. He was cuffed, taken to the cop shop and booked.

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.

Choice -- who made it to the top eight on "The Voice" last season -- was arrested shortly before 2 A.M. Sunday in South Carolina ... after a state trooper pulled him over.

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 has to enter an alcohol education program, and attend a weekly AA class for 10 weeks.

As TMZ first reported ... Erin was busted last December for felony hit-and-run and drunk driving. She plowed into 3 cars before cops stopped her.

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.

Michael Phelps says he's going to rehab ... this, after his 2nd DUI arrest in 10 years.

Phelps says the days following the Sept. 30th arrest have been "extremely difficult" ... and he acknowledges it's not the 1st time he screwed up.

"I am extremely disappointed with myself. I'm going to take some time away to attend a program that will provide the help I need to better understand myself."

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."

TMZ Sports broke the story ... Phelps was busted in Baltimore after an 8 hour gambling binge at a local casino last week. Back in 2004, he was arrested for DUI in Maryland.

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.
