Jamie Lynn Spears' baby daddy got arrested for drug possession after police say they found him out cold behind the wheel of a vehicle. 

Cops in Mississippi busted Casey Aldridge last week, and according to the arrest report, obtained by TMZ, he had several different prescriptions pills on him.

Officers were responding to a call for a suspicious vehicle parked alongside a road in Natchez, MS. Police say they found Casey passed out in the driver's seat and transported him to a local hospital.

Once he came to, he got the bad news ... you're getting arrested.

We're told Casey was booked for possession of Oxycodone, lorazepam, Xanax and drug paraphernalia. 

Casey and Britney Spears' younger sister have one daughter together ... 10-year-old Maddie.

Jamie Lynn was 16 when she got pregnant back in 2007, and Casey was 18. They got engaged but eventually broke off their engagement. 

JLS is now married to Jamie Watson, and they had a little girl, Ivey Joan, last year. 

Khloe Kardashian has thrown in the towel, breaking up with Tristan Thompson after she found out her baby daddy allegedly cheated on her with Kylie Jenner's best friend ... TMZ has learned.

We're told Tristan flew into Los Angeles to spend Valentine's Day Thursday with Khloe and their daughter, True. On Sunday night he was at a house party, where we're told he snuggled up with Kylie's BFF, Jordyn Woods. 

Witnesses tell us Tristan and Jordyn were all over each other ... making out. We're told Khloe found out and immediately broke things off with the NBA player ... a source tells us "she has had enough." 

We're told there's little chance for reconciliation ... Khloe and Tristan are done. 

You'll recall back in October 2017, Tristan was at a hookah lounge in Washington D.C. where he motorboated a woman and got handsy with another. The video surfaced days before Khloe gave birth, and just before she delivered he was seen on video going into an NYC hotel with yet another woman.

Khloe hasn't been back to Cleveland much this season, though the 2 still remained together. She was on hand when Tristan's team ended an extended losing streak. 

We don't know Kylie's reaction to the latest development, but she and Jordyn have been inseparable.

J Alexander is blasting Burberry for showcasing a hoodie with a noose around the neck ... saying the people who gave it the green light are the ones who should be hanged! 

We got the famed "American's Next Top Model" coach Tuesday at LAX, and he didn't hold back in his criticism of Burberry's design from London Fashion Week. 

As you might know ... Burberry apologized after getting tons of backlash for showcasing the noose hoodie, calling it a mistake and insensitive. Even the model who was forced to wear the hoodie is speaking out, saying "suicide is not fashion." 

But, on the heels of racist blunders from Gucci and Prada, Miss J ain't havin' it!

You gotta see his call for Burberry to be brought to fashion justice. Basically, he thinks the brand deserves a taste of its own medicine -- but he says in his own VERY colorful way.

Just watch. 

Andy King's blown away by his newfound fame -- courtesy of his infamous scene in Netflix's "Fyre" documentary -- but admits he almost missed out, because he wanted it on the editing room floor.

The event planner who offered oral sex in exchange for a load of Evian water for the doomed Fyre Festival ... told us he begged producers to axe that part of the story. While he was on TMZ Live today he revealed why the director put the kibosh on that.

Andy's now glad he did, because TV and movie offers have been rolling in since the doc aired, and he's riding the wave of being a social media hero while he can.

As we told you ... Andy's already teased a TV project he's working on, but it sounds like there's a lot more in store for him. There could be even more excitement, too ... if Ja Rule comes calling.

Andy didn't leap at Ja's second attempt at a Fyre-like fest -- but he doesn't rule it out, either.

21 Savage's face kinda says it all -- 2 days after ICE finally released him, he had to pose for this mug shot in his felony theft case. Sooo ... zero reason to smile.

As we first reported, the rapper turned himself in to cops last Friday in southern Georgia. He was booked for theft by deception for allegedly skipping out on a 2016 concert.

The case came up again after his ICE arrest, because the concert promoter, Karen Smith, decided to go after him for the $17k she says he made off with when he bailed on the show.

Smith says 21 demanded he be allowed to carry a gun onstage -- which she caved to -- but says he bounced when he got annoyed about the opening act, who was a local rapper.

A warrant for 21 Savage's arrest had been sitting for at least 2 years, and he surrendered last week at the Liberty County Sheriff's Department. 

Considering he'd just been released from an ICE facility on bond, it's no surprise he didn't look pleased in the mug. He was booked and released within half an hour.

Lady Gaga and her fiance have called off their engagement ... ending their two-year relationship ... TMZ has confirmed. 

The singer and Christian Carino started dating back in February 2017 around the time she performed at the Super Bowl halftime show and just months after she called off her engagement to Taylor Kinney. Her relationship heated up fast with Christian ... wasting no time kanoodling with him in the Hamptons.

It's unclear when exactly the 50-year-old agent proposed ... but during a speech at Elle's 25th annual Women in Hollywood Celebration in October 2018, LG revealed the engagement when she thanked "my fiance, Christian."

There were signs the relationship was on the rocks ... fans noticed Christian was nowhere in sight when she hit up the Grammys. He was also absent from Gaga's Instagram feed on Valentine's Day.

People was first to report the news.

Mark Geragos reportedly is close to becoming Jussie Smollett's new criminal defense lawyer, and all signs were pointing to it Monday night. 

Geragos appeared on CNN and made a ferocious case supporting Jussie and throwing major shade on the Chicago Police Department. Geragos suggested the leaks coming from the police were a thinly veiled attempt to skewer the actor.

We realized what was up the second Geragos appeared on Anderson Cooper's show and made repeated contacts with Geragos trying to find out if he was representing him -- it was the only way to read his comments. Geragos did not get back to us. 

There are now reports he is close to representing the actor who is now in the crosshairs of the police department.

TMZ broke the story, a grand jury is about to convene to hear evidence as to whether Smollett should be indicted on the felony charge of filing a false police report.

Smollett has vehemently maintained the attack was real.

12:25 PM PT -- We just caught Meghan on her way back into The Mark Hotel after lunch at Cafe Boulud with friends. The day of celebration for the royal and her bump continues!

Meghan Markle's celebrating the upcoming birth of her first child with Prince Harry ... and she's doing it on U.S. soil, baby!! Take that, UK.

We just got a shot of Meghan outside The Mark Hotel Tuesday afternoon in NYC. She held her baby shower there and, as you'd expect, she was flanked by tons of security as she got into a waiting SUV.

As you can see ... Meghan's doing the expectant mommy thing, cradling her baby bump with every step. The Duchess of Sussex is about 7 months pregnant, and she and Harry have been hinting the baby is due in April. 

Meghan's flying solo, sans Harry, for this trip. The baby shower could be the last time she sees her friends -- at least stateside -- before she gives birth.

10:21 AM PT -- A rep for the Fashion Nova brand tells us, "Fashion Nova is an ultra-fast fashion brand that is capable of executing design within hours and believes in fairness in pricing. We strive to offer our customers affordable leading trends. We respect the fashion community and work with a variety of vendors, designers, influencers and celebrities to keep our style offering fresh and relevant."

The statement continues, "Kim Kardashian-West is one of the top fashion icons in the world that our customers draw inspiration from. However, we have not worked with Kim Kardashian-West directly on any of her projects but have been driven by her influential style."

Kim Kardashian West is going after fashion companies like Fashion Nova for jacking original designs and promoting them as their own, or even worse -- making it seem like she's in cahoots.

KKW says it's "devastating" to see brands "rip off designs that have taken the blood, sweat and tears of true designers who have put their all into their own original ideas." Kim doesn't name Fashion Nova  ... but it's pretty obvious they're the target.

She's specifically referencing the black, one-of-a-kind vintage Mugler dress she wore at the Hollywood Beauty Awards Sunday night -- which instantly went viral.

The next day, a knock-off version of that dress popped up on FN's website, but only for waitlist. Kim claims this is because the dress obviously hasn't been made to sell yet, and it's simply a ploy to attract customers by tricking them into thinking Kim has a relationship with the company.

Kim adds ... "I’ve watched these companies profit off my husband’s work for years and now that it’s also affecting designers who have been so generous to give me access to their beautiful works, I can no longer sit silent."

She's also warning folks not to believe what they see online, emphasizing she's built relationships with amazing designers to pull off her famous looks, but -- "I don’t have any relationships with these sites. I’m not leaking my looks to anyone, and I don’t support what these companies are doing."

As you may know ... celebs like Cardi B and Amber Rose have collabs with Fashion Nova. Kim's making it clear -- she doesn't.

12:47 PM PT -- TLC is also mourning the loss of Sean, stating, "TLC expresses its deepest sympathies to Sean's friends and family at this difficult time."

They also released a clip of Sean from last summer -- when the show caught up with him a couple years after his episode aired in 2016 -- at the time he was coping with the loss of his mother.Sean Milliken -- who starred on TLC's "My 600-lb Life" -- is dead ... TMZ has confirmed.

His father, Matt, announced the sad news on Facebook ... saying Sean passed away Sunday in a hospital due to complications from an infection. He added, "Sunday he was having problems with his breathing, they were able to resuscitate him and a short time later his heart stopped." 

Sean, who reached a weight as high as 900 pounds, was on the show for only one episode in 2016. He became bedridden during his senior year of high school -- when he was already at least 400 lbs -- after suffering a debilitating leg injury.

The same year he appeared on the reality show, he told People he was planning on moving to Houston to see if he could qualify for weight loss surgery. He reportedly lived on his own in Texas prior to his death, but it's unclear if he ever went under the knife.

Sean was 29. RIP
