George Zimmerman was on the hunt today -- for a shotgun ... TMZ has learned.

Zimmerman went to Kel-Tec in Cocoa, Florida ... a gun manufacturing company. We're told he was asking questions about the legality of buying a shotgun -- specifically, the Kel-Tec KSG.

The gun in question is a tactical shotgun, often used for home defense. It holds 12 rounds of 12 gauge shells.

And this is interesting ... Kel-Tec manufactures the PF-9 gun -- the pistol Zimmerman used to kill Trayvon Martin.

We're told the owner's son took Zimmerman on a tour of the grounds, including the area where the firearms are assembled. The photo of Zimmerman and an employee (above) was taken inside the assembly plant.

It's unclear if he actually bought the shotgun while he was there.

Less than a week after celebrating her 55th birthday ... Madonna ventured out in Rome Wednesday wearing a shiny gold grill piece.

2005 called ...

Lindsay Lohan is fiercely defending her decision to hang with a friend who has an even more checkered past with drugs than her, and actually thinks it's a positive step for her recovery -- problem is ... she's delusional.

Sources close to Lindsay tell TMZ ... she doesn't understand why her shopping trip with Vikram Chatwal would raise concerns she's hanging with a bad crowd, and putting herself in danger of a relapse.

As we previously reported ... Chatwal was busted for drug possession in April, but avoided jail by agreeing to 12 months of in-patient rehab.

We're told Lindsay thinks Vikram is good company because, like her, he's been through several rehab stints ... and is currently in recovery.

Here's the flaw in that argument ... multiple drug counselors -- from reputable clinics -- tell us Lindsay's playing with fire by hanging with old friends connected to her partying ways.

Most counselors told us ... it's "not recommended" for recovering addicts to hang with another addict -- especially if it's been a short stretch since they got out of rehab.

Lindsay's been out for 22 days, and while it's unclear when Vikram was last in treatment ...his drug bust was just 4 months ago. Not to mention, neither volunteered for rehab, but had to be forced by a judge.

Sean Combs is a corporate tyrant who had the audacity to force an unpaid intern to ... gasp ... GET COFFEE ... this according a new lawsuit obtained by TMZ.

The ungrateful person behind the suit is Rashida Salaam -- who claims she took a gig as an unpaid intern for Bad Boy Entertainment from January 2012 to May 2012 and couldn't BELIEVE the kinds of work they had her do for free:

-- answering telephones
-- getting lunch and coffee for paid employees
-- making deliveries
-- gift-wrapping presents
-- decorating the office during holidays

Just torture ...

Salaam probably has a real case, thanks to recent changes in the law regarding unpaid internships (no more free labor for course credit) ... but we're guessing she's probably hurting her chance at landing a full-time gig with the company by filing the suit.

"Homeland" star Damian Lewis hit the beach with his family in Ibiza, Spain this week ... which inspired a couple of bad terrorist-themed jokes at the office. Here's what we came up with ...

-- Abu Nazir would be proud ... 'cause that body's tha bomb, yo!
-- Waterboard? More like water excited!
-- The Shore on Terror
-- HomeSand
-- Al-Tide-a
-- Homeland Sea-curitry
-- Seahaad
-- Code: Pale anyone?
-- Sui-tide Bomber
-- U.S. Marina Corps

We could go on, but they're only gonna get worse ...

Brace yourselves, this might be the most hilariously embarrassing video we've ever seen -- sent by "Criminal Minds" star Thomas Gibson to a random stranger on the Internet ... after he got catfished hook, line, and sinker.

Here's the full story: a woman contacted Gibson on Twitter roughly two years ago, using a photo of a scantily clad woman, and told Gibson she was a huge fan. Gibson took the bait.

The woman -- who refused to tell us her age or name -- is from North Dakota. She says she carried on a 2-year relationship with Gibson (who's married) exchanging multiple explicit photos and video with him, using images she stole from various pornographic websites (including LoveGisele.com).

The result ... Gibson was smitten. Seriously, you have to watch the video, which he shot around Christmas last year in Utah. It's like the hot tub scene from "Austin Powers."

The woman says she actually developed feelings for Gibson too, and everything was going well until a few months ago, when she got a letter from Gibson's lawyers demanding she cut off contact ... because Gibson had discovered her pics were fake.

Shocker ... she says she hasn't heard from Gibson since. Too bad because the hot tub looked fantastic.

Robert Pattinson violently SHOVED a guy he apparently thought was a snap-happy photog while exiting a club Friday night ... but turns out it was a security guard.

In the chaotic video -- taken outside the Troubador -- a boozed-up looking Robert is seen trying to leave the venue while swarmed by paps. You can tell it's tough to navigate.

As Robert makes his way to his car through the mayhem, he suddenly throws his hand to another guy's face ... forcefully PUSHING him backwards. Suddenly paps are heard asking, "Why'd you hit him?"

Afterwards, the vic -- who is actually part of the bar's security team -- is heard saying "He grabbed me on my face" as he picks his glasses up from the ground.

He also makes it clear Robert thought he was someone else -- a photog.

Jennifer Lopez must sure think Casper Smart is cute, because upstairs there's a vacancy -- he just ruined her big announcement that she's returning to "American Idol."

Smart was promoting his new show -- yes, anyone can -- when he was asked if his GF was coming back to the struggling show. He dug deep and said, "Yes."

Apparently Casper thought the cat was already out of the bag.

Looking like an androgynous Captain Morgan with blonde hair, a lipsticked Richard Simmons stepped out in L.A. Tuesday, inexplicably wearing this borderline insane red costume.

Kinda reminds us of the Starburst little lad guy.

The backlash against Kendrick Lamar is in FULL SWING ... with Diddy putting the rapper on blast on Instagram ... and he's even dragging Jay-Z into the attack.

Lamar has been under fire for the past 24 hours for the lyrics he spits out against other rappers on Big Sean's new track, "Control" ... in which KL refers to himself as the "King of New York."

Naturally, Diddy took issue with the lyric ... considering, well, you know ... he thinks HE'S the king of New York.

So Diddy fired back with an image on Instagram, showing himself and Jay-Z, another New York boss, laughing ... along with a caption that MOCKS Kendrick's lyrics.

"Big Time Rush" lead singer Kendall Schmidt has taken the phrase "man's best friend" to a whole new level -- by tattooing the face of his dog Sissy on his back ... and TMZ has the photographic proof.

Sources close to Sissy -- Kendall's adorable Boston Terrier -- tell TMZ ... the singer immortalized the pooch's mug onto the left side of his back a few weeks ago at Smith Street Tattoo in Brooklyn.

We're told the ink job took about an hour and was pretty painful -- but it won't be his last ... especially if he ever gets another dog.

Heidi Fleiss is a MARIJUANA BARON ... so say authorities in Nevada who charged the former Hollywood madam with pot possession after finding nearly 400 plants on her property, TMZ has learned.

According to law enforcement, officials pulled up to Heidi's home in Pahrump on August 7 looking for another woman ... when they stumbled upon a gigantic weed farm.

Eventually, officers made contact with Heidi ... who admitted to owning the plants and said she was growing the weed for a "cooperative in Las Vegas."

Problem is ... Heidi doesn't have a license to grow.

Cops say ... in total, they found 392 suspected marijuana plants -- which were all collected as evidence.

Fleiss was charged with several crimes -- including possession of marijuana with intent to sell, possession of drug paraphernalia and maintaining a home where drugs are sold/used.

However, cops say Fleiss was NOT arrested ... "due to the fact that she has approximately $200,000 worth of exotic birds in the residence plus she gave us consent to search without a warrant and was very cooperative throughout the investigation."

Soulja Boy has a lot in common with Alec Baldwin -- not that he's as talented, but he's definitely as disrespectful on American Airlines, because the renegade rapper got booted from an AA plane after causing a pre-flight scene.

Just like Alec, Soulja was on American Airlines Friday when the flight attendant took the mic and told everyone to sit the f**k down. Soulja, who was standing and walking the aisles, didn't follow the command.

Just like Alec, a flight attendant approached the rapper and repeated the order and explained the consequences if he didn't obey.

Just like Alec, the rapper blew her off.

And just like Alec, he was "removed" from the plane.

Unlike Alec, Soulja was actually contrite, telling TMZ, “It was a bad night and me and the flight staff didn’t see eye to eye. In hindsight, I’m extremely sorry for all inconvenience caused to the passengers and employees of the airline.”

Selma Blair is mixing fun bags with shopping bags -- the former "Anger Management" star was unabashedly breastfeeding in plain sight at one of the biggest shopping spots in L.A. like it was no big deal.

Blair was spotted at The Grove with her 2-year-old son ... pumping the kid full of breast milk on a trolley, surrounded by shoppers.

"Big Brother's" got nothin' on Tyga -- 'cause the rapper says he's no fan of "gay ass" stuff.

The comments came flying out of Tyga's mouth outside Supperclub in Hollywood this week ... when a TMZ photog tried to ask the "Make It Nasty" rapper about the two $10 million lawsuits he's facing from some ladies who say their nipples were exposed in a Tyga music video.

At first, Tyga addressed the question -- saying, "Look at my car. Do I look like I care about a lawsuit, bruh??"

Then, he unleashed the insults on our photog -- "What you got a camera for? That's gay as s**t."

He continued, "You got a CAMERA on a n**ga ... go in [the club] and get some bitches."

When our guy explained that he was doing his job, Tyga shot back -- "That's a gay ass job."
