It's happening ... it's really, really happening ... *NSYNC is reuniting on the VMA stage -- this according to the band's official Twitter.

It's kind of ironic ... Twitter didn't even exist when *NSYNC was famous -- but that didn't stop the boy band from all-but-confirming their HIGHLY anticipated MTV performance in 140 characters or less, writing, "mic check, mic check one ... two ... is this thing on?!"

Miley Cyrus hit the streets of NYC yesterday ... on some sort of fruitless search.

BTW ... we think she looks hot ... ripe for the pickin'.

Chris Brown is the victim of a racist ass District Attorney -- so claims Chris Brown.

The ever-deflecting singer went on a twitter rant last night, ragging on authorities for calling him out for submitting bogus community service reports in the Rihanna beating case. The judge ordered Brown last week to do 1,000 hours of additional, legitimate community service.

Apparently Brown has been steaming over the ruling, and exploded last night, saying, "Nigga done 6 months community service wit police and the DA racist ass crying to the judge that I didn't do it. F**k the SYSTEM!"

Fun Fact -- the actual L.A. County D.A. is an African-American woman.

Brown thinks punishing men for beating women at a point is ridiculous, saying, "How about y'all take care of all the homeless kids and families on skid row." And then there's this defiance: "Family first! The LAW ... last."

And for final bad measure, Brown referred to his last mobile edition to his art collection -- "I paint pics of monsters because its a reflection of u bitchass niggas and this bitchass system!"

Beating women can be such a bitch.

Debbie Rowe is furious that someone sold pictures of her daughter, Paris Jackson, at a boarding school where she's been for more than a month ... and she plans to sue the people who sold her daughter out ... TMZ has learned.

Sources connected with Rowe tell TMZ ... Paris' mom is extremely upset that someone at the boarding school -- located outside California -- has not only sold pictures but information about the girl.

The pictures -- one of which was plastered on Twitter (above) -- were taken a month ago during a graduation ceremony, shortly after Paris arrived. By the way, the plan was for Paris to attend the school on the QT ... she used a pseudonym.

Rowe is beyond angry, telling friends, "These people, including some websites, are screwing with my daughter's ability to get better." TMZ broke the story, Paris attempted suicide in June after taking pills and slitting her arm with a meat cleaver.

We're told Rowe wants TMZ to post her promise to sue, because she wants people at the school and everyone else to stop selling out her daughter for cash.

Kanye West left an innocent photog in crutches after a brutal assault at LAX last month -- when Kanye attempted to wrestle away the pap's camera -- so says the photog himself, and now he's filed a lawsuit against the rapper.

Daniel Ramos appeared with his lawyer Gloria Allred at a news conference Wednesday, where Gloria announced the lawsuit for assault, battery, and interference with Daniel's civil rights (in this case free speech).

Daniel -- who called himself a "filmmaker" -- says he spent two weeks on crutches after the attack, and has been walking with a cane for some time. He says he's still in pain.

Gloria argued the attack sets a dangerous precedent for celebrity-on-photog violence, especially now that various celebs are actually celebrating unprovoked attacks on photogs.

At one point, Gloria went after Kirstie Alley, Cher, and even Kylie Jenner for applauding Kanye's attack on Twitter.

Gloria says she's also asking the court to issue a restraining order against Kanye.

There once was a man from Missouri ... who almost died in a freak car explosion -- but now, Dick Van Dyke is actually joking about his near death experience in the form of a limerick.

The 87-year-old funnyman -- who calls himself the barefoot prince of Malibu on Twitter -- posted the poem on Twitter yesterday ... writing:

"I once drove a car that could fly
I had never driven so high
But, I recently found
Even back on the ground
U still can be left high and dry"

He also posted a photo of the burned out remains of his ride along with the caption, "Used Jag for sale REAL CHEAP!!"

"Criminal Minds" star Thomas Gibson wasn't pulling a fast one on his wife by conducting an online relationship with a shameless catfisher -- sources tell TMZ, the actor and his wife have been separated for years.

Sources close to the couple tell us, Gibson and his estranged wife Christine Gibson still live together for the sake of their children, but they've been separated for 2-and-a-half years ... six months before Thomas started messing around with one of his Twitter fans.

As we reported, Gibson and the woman -- who catfished him by posing as a porn star -- carried on a heated relationship for two years before Gibson discovered the entire thing was a sham ... he even sent her a sexy hot tub video (it's hilarious).

Bottom line: Gibson might be a sucker ... but he's no cheater.

Randy Jackson is pissed that his niece, Paris Jackson, is confined in what he believes is a psychiatric hospital and thinks something really stinks ... but Paris' mom thinks he's delusional.

Randy just tweeted, "I just hate the fact that you [Paris] will probably still be there on my brother's birthday." Randy adds, "She is not psychotic. There is no reason for her to be in a psychiatric hospital this long away from her family."

But we've learned Debbie Rowe, Paris' mom, is livid at Randy and is telling friends that he doesn't know what he's talking about. We're told Rowe said, "As usual, he's grossly misinformed. He doesn't know what he's talking about. He has no idea where she is. She's not in a psychiatric hospital."

Rowe is saying Randy is just bitter because no one wants him to testify in Michael Jackson's wrongful death trial because he's irrelevant.

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.

Kendrick Lamar called mainstream rap on the carpet this week ... and it's clearly pissed off Diddy and his cohorts. Meanwhile more professional athletes are coming out of the closet. So we gotta ask ...

After a lifetime of shying from social media, Prince has FINALLY joined the Twitterverse ... and instantly became "that guy" who posts photos of his food.

Dammit Prince.

The singer fired off his first tweet last night under the handle, "@3rdeyegirl -- and it read, "PRINCE'S 1ST TWEET... TESTING 1,2..."

His 2nd tweet read -- "PRINCE'S 2ND TWEET."

Followed by Tweet #3 -- a photo of his over-peppered salad, with the caption, "DID EYE ADD 2 MUCH PEPPER?"

Yes, Prince ... you did.

The Purple One polished off his first string of insightful tweets with an inaugural "selfie," a close-up shot that's barely discernible as his hair.

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.

You tag Phil Jackson in a rap song, he'll tag you right back -- just ask Kendrick Lamar ... who got a free lesson in ego management from the Zen Master after droppin' his name in a new song.

67-year-old Jackson was definitely listening when 26-year-old Lamar called him out in Big Sean's new song, "Control" -- a song that includes the lyrics:

"Who the f**k y’all thought it’s supposed to be?
If Phil Jackson came back, still no coachin’ me
I’m uncoachable, I’m unsociable."

Jackson -- who's no stranger to dealing with egomaniacs (or people named Lamar) ... shot back on Twitter moments ago ... with a message aimed right at Kendrick:

“@kendricklamar it’s okay to be cocky and sure, but we all need somebody to lean on. Let’s just call it mentoring."

Monday was theme day for Chris Brown, first showing up at an L.A. jail -- where orange is standard issue -- to turn himself in for his hit-and-run case, and later that day partying at AV nightclub sporting an orange hoodie and zooming off in an orange Lambo.

Chris apparently had a long night, because at 6:34 AM Tuesday, the ghost of Rihanna surfaced as he tweeted: "Being famous is amazing when it's for your music and talent. I'm tired of being famous for a mistake I made when I was 18. I'm cool & over it."

Forget babies, food and cat photos -- these stars were so proud of their bronzed backsides they took to the interweb to shared their beachin' butts!

Can you guess which sexy stars are the proud owners of these perfect posteriors?

Following Geraldo Rivera's lead, Ice-T just posted a topless selfie on Twitter to prove he's still pretty jacked ... for a 55-year-old.

Along with the pic, the "Law & Order: SVU" star included the caption, "This morning: MFs popin sh*t ... 55yrs old. 'Don't sleep on the old cats.'"

Unlike Geraldo, T had the decency to wear pants. But, dude, what up with the blur?
