Private security firms have been inundated with calls since the cold-blooded murder of UnitedHealthcare CEO Brian Thompson ... but the high-profile case won't necessarily change how companies protect execs long-term, TMZ is told.

In the days since Thompson was shot dead on the streets of NYC ... multiple private security firms have been flooded with service inquiries and price quotes.

Babcock caught up with the former national champion following the Wolverines 13-10 win over his alma mater on Saturday. While Clarett hoped the team would compete for the Big Ten championship this weekend, he's not going to cry over spilled milk.

"I'm not the person to cry over one moment when you have a bunch of other things in front of you. We still have the playoffs coming up. Chances are we'll play here either December 21 or 22, and we have a handful of games."

LL Cool J only needs a mirror to see the "greatest rapper of all time" -- a claim that's not getting any pushback from Slick Rick.

If LL says he's the G.O.A.T. -- it's because he coined the term!!!

TMZ Hip Hop caught up with the legendary rapper at LAX on Thursday ... MC Ricky D got his start a few years after LL on Def Jam Records and for all intents and purposes, holds his own place in hip hop history.

Whitney Cummings says rejecting Sabrina Carpenter from "The Conners" was the best thing that could have happened to the pop star.

We got Whitney on Thursday at LAX and our photog asked the former 'Conners' showrunner about the time Sabrina tried to get on the show.

OnlyFans model Sophie Rain's net worth could get even bigger ... if she's willing to cash in on the X-rated offers she's received following her viral payday.

Flavor Flav's all about fighting the power, standing up to NBC security ... but, it seems they were just doing their jobs -- 'cause we're told he wasn't expected at the tree-lighting, and security booted him.

Here's the deal ... Flav took to X to air some grievances about NBC kicking him out of the Backstreet Boys dressing room at the the Rockefeller Center tree lighting ceremony Wednesday night -- despite all his work with them during the Olympics.

However, sources tell TMZ security had a very good reason to kick him out of the event ... 'cause he wasn't on the list of expected attendees.

Taylor Lorenz -- a controversial journalist formerly of the Washington Post -- is clarifying some of her comments about the murder of UnitedHealthcare CEO Brian Thompson ... and she says his brutal killing isn't the real tragedy here.

Taylor joined us on "TMZ Live" Thursday and we asked her what she meant by two social media posts that have gotten a lot of attention in the wake of Thompson's killing ... including one that lots of folks interpreted as her calling for more violence against healthcare executives.

She says she wasn't calling for murder when she shared a photo of the Blue Cross Blue Shield CEO Kim Keck above a post about BCBS announcing it wouldn't cover anesthesia for the entirety of some surgeries.

A former bodyguard for Brian Thompson, the UnitedHealthcare CEO who was shot and killed in NYC, is in complete disbelief the exec didn't have security when he was murdered.

Philip Klein, whose Texas-based security firm Klein Investigations previously provided bodyguards for Thompson in the 2000s, tells TMZ ... he is "shocked and baffled" to see the high-profile CEO didn't have a "detail" (at least 10 security guards) with him while out and about in Manhattan -- given the malevolence the insurance industry often faces.

He also says Thompson should've been wearing a vest in addition to having guards by his side, but adds ... he likely didn't have it on due to personal preference.

Daz Dillinger doesn't feel he's going out on a limb declaring the West Coast had the best rhythm and flow over hip hop this year ... Kendrick Lamar reached another stratosphere, Snoop Dogg was all over the globe and Tha Dogg Pound reunited!!!

Lil Durk is facing a legal slugfest, with the feds claiming he's the mastermind behind a murder-for-hire plot ... and his attorneys are convinced it's a classic example of prosecutors grasping at straws with some street-savvy rap lyrics because they don't have a real case against the rap star.

The Chicago rapper's attorneys -- Drew Findling and Marissa Goldberg, of The Findling Law Firm, P.C., along with Jonathan Brayman, and Christy O'Connor -- tell TMZ Hip Hop ... "When you see an artist’s rap lyrics quoted as 'evidence' against them, it is a glaring indication that there is no real evidence against that person."

According to the feds, Durk detailed the steps that led up to the August 2022 murder of rival Quando Rondo's cousin Saviay'a Robinson on Babyface Ray's song "Wonderful Wayne & Jackie Boy" when he rapped ... "Told me they got an addy (gooo) / Got location (gooo) Green light (go, go, go, go, go) / Look on the news and see your son, You screamin’, 'No, no' (p***y!!!)"

Tyler Perry is all about one leading lady -- calling it a dream come true to work with Oprah!

We caught up with Tyler Wednesday, and he couldn’t stop gushing about directing Oprah for the first time in his new Netflix film, "The Six Triple Eight" ... making it clear that teaming up with the cultural icon is nothing short of incredible.

BigXthaPlug had zero tolerance for a couple of fightin' fans disrupting his show in Los Angeles last night -- and had security swiftly throw both of the dudes out, so fans could enjoy the show!!!

TMZ Hip Hop obtained footage of BigX on his sold-out Take Care Tour at The Regent in DTLA … performing the fan-favorite track “Law & Order” -- you know, the one that borrows its bounce from the series Ice-T helped build.

The Dallas-born rap star didn’t even get to his “woo-wop” rhymes when he spotted a couple guys scrapping and immediately stopped the show for some law & order on his terms!!!

Barron Trump isn't soaking up the spotlight while attending New York University, and he's using video games to socialize with his peers ... this according to current students.

TMZ spoke with several students at the prestigious Manhattan university, who tell us Barron spends little time on campus ... quickly moving in and out of buildings while surrounded by Secret Service agents and transported in an SUV.

Basically, playing hacky sack in the quad ain't his thing.
