The United States conflict with Iran has had Americans freaked the f**k out lately -- and, accordingly, they've been looking far and wide to burrow themselves underground.

TMZ spoke with some of the best bunker retailers in the biz, and wouldn't you know it ... they say their sales and window shoppers have gone through the roof over the past week or so as missiles and nuke threats have been flying back and forth in the Middle East.

Let's start with Rising S -- which hawks pretty pricey shelters, ranging from $45k to a whopping $1 million. They tell us bunkers have been selling like hotcakes since Trump took out Gen. Soleimani. RS says they've sold 17 bomb shelters since then. A recent uptick of 150%.

Rae Sremmurd's mother says her son who's been accused of murdering his father and her ex-husband suffers from a mental illness requiring medication ... which she claims he's been off of as of late.

Bernadette Walker tells us her 19-year-old son, Michael Sullivan, deals with Schizoaffective disorder ... which lends to schizophrenia, as well as symptoms including hallucinations, delusions and mood disorders, such as mania and depression.

She says Michael was living with her in Atlanta until this past November, when she says he stopped taking his meds, leading to outbursts of anger that became more frequent. Bernadette tells us Michael eventually went to live with his dad, Floyd, in Mississippi.

Some of Travis Barker's former rides are hitting the auction block ... and you can bump his tunes in a vintage Caddy or Chevy ... if you're ready to break the bank!!!

Sources close to the Blink-182 drummer tell us he's decided it's out with the old and in with some new whips, so he's partnering with Barrett-Jackson to auction off 3 cars -- a 1941 Cadillac 62 Series Convertible, plus a 1960 Cadillac Coupe Deville and a 1972 Chevrolet K5 Blazer.

Our sources believe the convertible could fetch up to $100,000 ... and the souped-up Chevy could hit a whopping $200K. Ya better have some deep, deep pockets!!!

Travis is an avid car collector, but we're told he's moving his professional life into a new space -- the warehouse he recently bought in SoCal will house his car collection, clothing brands and new record label, DTA Records -- and he wants to sell these rides to make room for new ones.

Travis is a HUGE fan of Caddys ... he's got at least 2 Cadillac tattoos, including an emblem on his chest and a Cadillac script down his rib cage which took 12 hours to create.

The Astros' and Red Sox's cheating scandals are much ado about nothing ... so says Pete Rose, who tells TMZ Sports sign stealing ain't that big of a deal at all.

The MLB legend says back when he was playing ... he NEVER got an advantage by stealing signs -- saying he was always worried the guy reading the catcher would be wrong.

"He might not have the signs -- he might tell you wrong," Rose says. "Now, if you're looking for a low-and-away breaking ball, and the guy throws an up-and-in fastball, you just got one off the kisser."

Of course, the Astros' and the Red Sox's alleged schemes were reportedly much more accurate than a dude standing on 2nd base relaying catchers' signals ... but Rose still says he doesn't care.

In fact, Pete tells us if players were that concerned about it all ... they should just take matters into their own hands and start beaming guys they think are cheating!!!

"I'm f**king serious, bro. You know how serious I take fighting."

That's Logan Paul telling TMZ Sports a potential boxing match with Antonio Brown is VERY realistic ... claiming he's already in talks with AB's camp.

"I think we might be closer than anyone expects," Paul says.

As we previously reported, Logan called out Brown in December -- saying the NFL star would be the perfect opponent to further his pro-boxing career.

Brown responded on social media -- telling Paul, "Square up." Brown has since told Complex he's down to scrap and wants to train with Floyd Mayweather.

So, when we saw Logan in L.A. promoting his brother Jake Paul's upcoming Jan. 30 boxing match against AnEsonGib on DAZN, we had to ask if all the AB fight promotion was real ... or just a gag.

Logan says he's not messing around -- he's deadly serious about getting a deal done and thinks Brown is highly motivated, too.

Paul says transitioning into fighting helped rehab his image after the incident in the Suicide Forest in Tokyo a few years ago ... and a high-profile match could do the same thing for AB.

"In many ways the KSI fight gave me a purpose. I think this would do this for Antonio Brown -- give him a nice pay day, give him a chance to redeem himself."

Paul thinks the fight could be HUGE -- a la Mayweather vs. McGregor.

Sasha Obama decided against rushing a sorority at the University of Michigan ... despite being the it girl on campus.

We've called around Ann Arbor ... the first round of rushing began Tuesday, and multiple sorority members tell us Barack Obama's youngest daughter wants no part of it.

For those unfamiliar ... rushing is the process of exploring all of a university's sororities, and interested students at Michigan must register before a deadline. We're told Sasha did not register.

TMZ broke the story ... at the beginning of last semester, UM sororities were champing at the bit to recruit Sasha in the spring, and she was dubbed a "rush crush."

All signs were pointing to Sasha rushing and pledging Alpha Chi Omega (AXO) -- she stayed at AXO's house once before enrolling, and her close friends from high school are members there -- but now she's following her mother's and sister's footsteps by not rushing.

Michelle Obama didn't join a sorority at Princeton, and Malia isn't living the Greek life at Harvard, where sororities are not recognized by the Ivy League school.

Looks like Sasha is looking for a similar college experience.

Justin Bieber will reveal in his documentary why so many people thought he was battling deep depression ... fact is, he was, but it was the result of contracting Lyme disease.

Sources who have seen the documentary -- which drops January 27 -- tell us Justin and others in his life discuss the scary symptoms he endured in 2019. He says during much of the year his condition went undiagnosed. Doctors struggled to figure out what was wrong with him, but couldn't put their finger on it until late last year.

You may recall this photo of Justin crying taken back in October. It's made clear in the documentary ... Justin was indeed batting extreme depression because he was suffering and no one knew what was wrong with him.

We're told no one knows how Justin contracted the disease, but it comes from a tick bite. Symptoms include rashes, headaches, fever and fatigue.

Nicki Minaj's wax figure unveiling in Berlin has drawn the ire of the Internet, but here's the thing -- she gave it her stamp of approval ... more than 4 years ago.

Turns out, the "new" Nicki wax figure at Madame Tussauds Berlin isn't new at all ... it's the same one unveiled in August 2015 at Madame Tussauds Las Vegas. We're told Minaj's wax likeness was moved to Germany because the museum loans statues out frequently to mix up the attractions at its various locations.

Also, for all the haters claiming Nicki's being disrespected because the figure doesn't look anything like her ... she disagrees. Our sources say, her team actually worked with the museum on the project in 2015, and she signed off on it before it went public.

The "Jeopardy!" boys facing off for G.O.A.T. status already have tons of cash to their names -- and with even more up for grabs ... we noticed they have very different spending habits.

TMZ did some digging, and it turns out Ken Jennings, Brad Rutter and James Holzhauer have chosen to splurge (or not splurge) on unique causes -- and you'd be surprised at who's done what with their dough. BTW, this new 3-day tourney's got a million-dollar cash prize.

That said ... let's get into the numbers a bit.

Starting with Ken, the guy's racked up a grand total of about $3.5 million in "Jeopardy!" winnings over the years between his regular 74-game streak in '04 and other tournaments he's competed in since. Looks like KJ's an investor type -- he's got quite the portfolio.

Ken's got a crib with an estimated value of $2.1 million in Seattle. He's also pledged 10% of his OG $2.52 mil haul to the Mormon church and has announced a couple other donations. Other monies are tied up in stocks and bonds.

James seems a bit more charitable, at least publicly. He's pulled in around $2.7 mil from "Jeopardy!" and a good amount has gone to charities like Project 150, Communities in Schools of Nevada, Vegas-Clark County Library District Foundation and the Lustgarten Foundation.

DaBaby is flying free and clear for an alleged brawl at DFW Airport ... because prosecutors will NOT file charges against him.

The melee went down last month when the rapper and a friend were accused of attacking a food stand employee. We're told DaBaby's lawyer, Michael Heiskell, presented video evidence to the Tarrant County D.A. showing his client didn't commit the assault ... and as a result prosecutors are falling back.

We obtained footage from the fight, showing the final moments of the scuffle ... which became an issue again following DaBaby's arrest in Miami last week. He allegedly beat up a concert promoter for shorting him $10,000 on his fee,

Lisa Vanderpump just couldn't resist taking a swipe at Bravo for skipping out on the tab for a "Vanderpump Rules" party ... but fortunately, the newest cast member has deep pockets.

Check out this video from Monday night's bash at Hyde on Sunset, where the cast was celebrating the 8th season of "Vanderpump Rules" ... Lisa grabs the mic and puts the network on blast for refusing to foot the huge bill. Shots fired!!!

Our sources say Randall Emmett, who is joining the show this year -- along with his company Emmett Furla Films and 310 Nutrition -- stepped in and dropped about $50,000 to throw his new cast members a lavish party complete with tons of food and an open bar.

Randall's engaged to "Vanderpump Rules" star Lala Kent, and he just produced "The Irishman."

Too Short even showed up for a short set thanks to David Weintraub Entertainment. ... we're told the two are super close.

Seems Randall's already endearing himself to the cast -- money and famous friends will do the trick. Lisa certainly likes him, a lot more than she likes those cheapskates at Bravo.

The rappers are already lining up to work with Antonio Brown after the NFL superstar released his first-ever music video ... with O.T. Genasis saying he wants to get in the studio with AB!!!

As we previously reported, the All-Pro receiver just dropped his rap single "Whole Lotta Money" ... which is about ... well, you know.

TMZ Sports spoke with the "Big Shot" rapper at LAX to get a critique on the track ... and while he doesn't hate it, O.T. says there's some major room for improvement.

"It's not bad," O.T. tells us. "He needs a little bit of tweakin' on his verses at least."

O.T. added ... "It's dope, the cadence is dope."

How dope is it??? Dope enough for the guy behind the insanely huge hit, "CoCo" to actually willingly hit the studio with AB as long as he keeps working on his craft.

We asked O.T. to give us a rating out of 10 ... to which he says "4.5" BUT "with a possibility of an 8."

O.T. gets real for a second and says it's gonna be tough for AB to be taken seriously because people will view him as a football player, but admits there's one athlete who was able to pull off a straight-up banger.

And, just like AB ... the song is about money.

"Ink Master" star Oliver Peck is packing up his tools and saying goodbye to the show in the fallout after his blackface scandal ... TMZ has learned.

Peck says his exit is a mutual decision, telling us ... "After filming 13 great seasons of Ink Master, the producers and I have decided it’s best to part ways." He also acknowledged the blackface pics, saying, "The offensive photos of me which recently surfaced from many years ago can only be a distraction to the amazing show I have loved being a part of and its many talented artists."

He ended on a conciliatory note, saying ... "I want to thank the show’s cast, crew, contestants and awesome fans. It’s been a blast and an honor and I wish my friends and colleagues the very best in whatever the future holds." He's been on as a judge since 2012.

Peck's now ex-employers at Paramount Network also denounced the scandal, saying ... "We, like many others, were appalled when we saw the photos of Oliver. We were glad to see his apology and accept that he is taking full responsibility for the damaging impact of his actions."

Master P says his HS hoops star son, Hercy, is already getting looks from big-time Division 1 schools ... but tells TMZ Sports he wants the biggest name in college hoops to hit him up.

Duke head coach Mike Krzyzewski!!!

Of course, Hercy's Minnehaha Academy just beat up on Zaire Wade and Bronny James' Sierra Canyon squad 78-58 in front of 17,000 fans on Saturday ... and the Junior contributed 9 points and 12 assists.

The game was nationally televised ... and after the exposure, P expects his son to get looks from huge programs -- and it's already happening!!!

"Arizona ... it's so many," Miller says. "Hopefully this summer they'll be on the radar."

P is clearly stoked for his son's progress as a sophomore in high school ... and hopes the biggest schools in the nation come knocking on his door.

Not only is Hercy a hooper, P tells us he's an A student as well!!

Miller also shouts out Hercy's teammate and top 10 recruit, Jalen Suggs, who just committed to Gonzaga ... saying the dude is already an NBA talent.

Fun fact ... Hercy and Suggs played together on the same AAU team in 5th grade ... and you know who the coach was???

Master P.

The woman who was the inspiration for Jennifer Lopez's character in "Hustlers" is suing the production company, claiming they used her likeness and her story without permission, and they defamed her in the process.

Samantha Barbash claims in her suit, producers approached her to get her consent for the movie and she turned a thumbs down on them. Despite the rejection, the flick was produced with J Lo playing a character obviously based on her. We broke a story back in Sept. that Barbash was pissed that she received a lowball offer from producers.

Barbash says the character in the movie is portrayed as "using and manufacturing illegal substances in her home where she lived with her child." She says it's untrue and offensive.

She's suing for $40 million -- $20 mil in compensatory damages and $20 mil in punitives. She also wants an order requiring producers to turn over all copies of the movie.

Barbash, who is being represented by Bruno Gioffre, is not suing J Lo personally but is suing her production company -- Nuyorican Productions.

Jamal Lewis says he's giving the slight edge to his 2000 Ravens team in a hypothetical matchup against this year's Baltimore squad -- and it's all 'cause of Ray Lewis!

We got the ex-Ravens RB out at LAX on Monday and we just had to ask ... who would win in a tilt -- his 2000 Baltimore Super Bowl team, or this season's squad?

Of course, the '00 Ravens are considered one of the greatest of all-time ... with their defense STACKED with legends.

But, this year's Ravens team is also considered one of the best ever -- mostly because of Lamar Jackson's insane running ability.

So, who would win? Lewis says he's pretty sure it'd be a stalemate ... but then appeared to give his old team the advantage.

"We did have Ray Lewis," Jamal said with a laugh, "So, we might be able to stop Lamar."

Of course, the hypothetical matchup will only be a thing if the Ravens can finish off this year. They get the Tennessee Titans on Saturday and will likely have to play the KC Chiefs for a spot in the Super Bowl the following week.
