MTV

'Buckwild' star Anna Davis got the crap smacked out her this week in Kentucky ... by a MASSIVE pole covered in strobe lights -- and TMZ obtained the nerve-wracking video.

The smackdown happened at Whiskey Barrel Bar and Dance Thursday night in Richmond -- where Anna was hosting an event alongside the DJ ... and the rig above collapsed.

It's unclear why the structure fell -- but Anna says her neck, back and head have been "throbbing" since ... and she plans to see a doctor if the pain persists.

10:03 AM PDT -- JWoww just took to Twitter to explain herself and apologize -- sorta. She says she was caught off guard when she made her comments. But she still calls Christie "disgusting and judgmental" for his views on gay marriage. She apologized for her earlier choice of words .. but not for how she feels about the Gov.

Chris Christie is "retarded" ... so says Jwoww who (along with Snooki) is clearly still feuding with the Jersey governor after a nasty run in with the guy earlier this year.

The Jersey gals were leaving Boa Steakhouse on the Sunset Strip last night when we brought up CC -- and that's when the smacktalk began.

"He's a disgrace to New Jersey," Jwoww said ... adding, "Just like we were."

The two sides have been beefin' for a while (Chris doesn't like the show, the girls don't understand why) ... and it all came to a head back in May during an encounter on the Jersey Shore.

At the time, Snooki told Christie, "I just wanted to meet you, and just, hope you start to like us.”

Mike "The Situation" Sorrentino says his addiction to prescription painkillers began after suffering a neck injury on "Dancing with the Stars" back in 2010 ... and he's still battling to stay sober.

We broke the story ... Sitch checked into rehab back in March 2012 -- and after his people initially insisted the MTV star was just suffering from exhaustion, they eventually admitted he was hooked on opiates.

Now, 32-year-old Situation is talking about his battle with prescription drugs ... telling the AP his addiction was so bad, he could barely dress himself.

"All I had to do was get dressed for a family function and I couldn’t do that. The shirt was laid out, the belt, the pants, everything. The shower was on. I couldn’t even get out of bed."

Sitch says it was at that moment, he realized he had a problem -- "If I can’t [get dressed], how am I going to continue?”

The former "Jersey Shore" star says he's still taking medication for his injury -- but undergoes counseling to keep his addiction in check.

He's also a paid spokesman for the company that makes his pills -- and participates in a program that helps spread awareness about opiate prescription painkiller addictions.

Paris Hilton may be climbing in the DJ world ... but there's one honor she has yet to receive -- the Skrillex stamp of approval.

Skrillex -- one of the biggest DJs on the planet -- was rollin' through JFK this weekend when we asked if he thought PH had legitimate talent behind the turntables, since she just signed a big DJ contract with a famous nightclub in Ibiza.

But the 25-year-old electronic music phenom behind the megahit "Bangerang" told us he couldn't sign off on Paris' skills, 'cause he's never seen her play. Same goes for Pauly D.

It's not exactly a diss, but a nod from Skrillex could be huge for either one of 'em. Just sayin' ...

Jared Leto shouldn't have gotten so upset when MTV decided to give him his "Best Rock Video" VMA award BEFORE the big show ... because the awards "don't f**king mean s**t," so says Foo Fighters drummer Taylor Hawkins.

In case you missed it, Leto told the Huffington Post he felt dissed by the pre-award ... saying, "Rock deserves a place there."

But Hawkins thinks Leto just needs to get over it ... telling TMZ, "Who cares? Those awards are nice but they don't f**king mean s**t."

Now THAT'S rock 'n' roll.

There are two reasons to watch this video of rapper A$AP Rocky ...

1) He addresses the confrontation between himself and a security guard behind the scenes at the MTV VMAs.

2) He's SOOOOO HIGH!!!!!!

As for the VMAs conflict ... our friends at Bossip obtained video of Rocky chewing out a security guard ... but his girlfriend Chanel Iman stepped in and pulled Rocky away. It's unclear what Rocky was so upset about, but it's clear he was pissed.

Rocky tells TMZ he's not a troublemaker ... he's a peacemaker ... and blows off the altercation as no big deal.

Now, someone get that man some Funyuns, STAT!!!

Justin Timberlake has given his official STAMP OF APPROVAL to Miley Cyrus and her crotch-thrusting, bear-grinding twerkfest at the MTV VMAs ... saying, "It's not like she did it at the Grammys."

Justin appeared on 102.7 in NYC this morning and told Jim Douglas -- "I like Miley ... I like Miley a lot."

"I think she's young. She's letting everybody know she's growing up."

Now, a rep for the Teddy Bear Fund -- an org. dedicated to giving out stuffed animals at abuse shelters -- tells TMZ, "Miley made a poor choice to use a universally loved children's teddy bear in an offensive way."

"There is always good art and bad art -- unfortunately ... this was bad art," the rep adds.

"Hopefully she might consider reversing this situation by giving lots of teddy bears to children in need of comfort."

We tried to find a rep for a foam finger organization -- but apparently, that's not really a thing ... yet.

Joey Fatone tells TMZ ... Kevin Hart was probably right -- there's a decent chance he DID let one rip during the *NSYNC reunion at the MTV VMAs.

Fatone arrived back to L.A. yesterday -- where we immediately grilled him for LYING TO OUR FACES in the days before the show ... when he told us he wasn't in NYC for a surprise performance.

Of course, Fatone insisted he wasn't lying -- that he really was in NYC for a birthday party and not for the VMAs ... but c'mon man!!!!! (Your pal Chris already admitted the plan was in motion a couple of weeks ago. Busted!!!).

But back to the mystery fart ... Joey says if he did blast one during the VMAs (as Kevin joked in the moments following the performance) Fatone says there's a reason the comic would know ... and it all has to do with Kevin's height (5'4").

Check out the clip.

Miley Cyrus and Lady Gaga went cheek-to-cheek in a heated category at the VMAs: Most Likely to Give Censors a Heart Attack!

Congrats, Miley ... on grinding your way to the top -- of a teddy bear, and Robin Thicke! Twerk twerk twerk twerk twerk ...

Chris Kirkpatrick is tearin' up the hearts of girls in their 20's (and 30's (and 40's (and 50's))) across the country -- after announcing on the radio this morning that last night's *NSYNC reunion won't happen EVER AGAIN!!

Chris went on the Miami radio show "Johnny's House" early Monday morning to discuss last night's not-really-a-surprise SURPRISE performance ... and dropped all the details about how the whole thing came together.

Chris says he got a call from Justin Timberlake a few weeks ago out of the blue ... who asked if he was available to perform at the VMAs. Chris' response -- a resounding HELL YES (duh).

The guys headed down to Miami to rehearse and that's where Chris says Justin dropped two bombshells: He didn't tell MTV about his top secret plans and yes, dancing would be involved.

The interviewer then asked about rumors of a possible reunion tour -- but sadly CK shot them down saying the reunion was a one time thing to support JT.

Sorry Chris. And Joey. And Lance. And you too J.C.

Robin Thicke ain't exactly in the dog house with his wife after allowing Miley Cyrus to dry hump him in front of millions of people at the MTV VMAs ... in fact, she couldn't be cooler about it.

Sources close to Robin's wife Paula Patton tell us she was all good with Miley touching Robin's crotch and kissing his neck during MTV's Video Music Awards ... despite reports that she went ballistic following the performance.

We're told Paula knew the performance wasn't gonna be G-Rated because there were "tons of rehearsals" before the show ... and there were no surprises during the performance.

Plus, she already let him kick it with all those naked hot chicks in the "Blurred Lines" video ... so you know she's got the stomach to watch her hubby in a super-sexually charged situation with another woman.

Robin -- you're a lucky man.

Didn't get a good view of Lady Gaga's incredibly hot thong outfit at the MTV VMAs last night? Well you're in luck ... here's a 30-second unobstructed view of Gaga's glorious ass while she flirted with Joseph Gordon-Levitt.

We have no idea what JGL is saying, but we'd be grinning too if we were standing next to Gaga's pretty-much-naked body. She even does a flirty twirl for the actor before giving him a hug and going back to her seat.

You're welcome.

Taylor Swift doesn't just write breakup songs about her ex-boyfriends ... she talks SMACK about them during award shows ... and last night, she got caught. On camera.

It happened when One Direction took the stage to present a Moon Man at the MTV VMAs for Best Pop Video.

FYI -- Taylor used to date Harry Styles (they broke up in January) ... but apparently, she's still harboring some resentment -- 'cause as the band rambled on, the camera cut to Swift ... who leaned over to Selena Gomez and mouthed the words, "SHUT. THE. F**K. UP."

There are people out there who swear Taylor wasn't cussing -- that she was saying the words, "Sorry for my arm."

Those people are stupid.

Lady Gaga and Miley Cyrus gyrated, thrusted and she-humped the hell out of the backup dancers at the MTV VMAs last night.

Question is ...
