Flash mobs usually pay homage to musicians who are no longer with us -- or at least ones who aren't right there -- but the Janet Jackson mob this weekend had a very special guest ... Janet herself!
But it wasn't a coincidence -- it was all to promote Janet's greatest hits album, which comes out Tuesday.
In webcam video obtained from a computer Nick Prugo used -- a comp cops believe was stolen -- the guy can be seen toking something from a pipe and seriously gettin' his belly-baring groove on to Ester Dean's "Drop It Low."
Pretty soon, the only thing up in smoke could be his freedom.
A group of well-choreographed Michael Jackson fans -- about 500 to be exact -- gathered in Leicester, U.K. to wish Michael Jackson a happy 51st birthday by re-enacting his famous "Thriller" video.
According to the group, they think they've set some sort of world record.
This is what happens when you're livin' on the edge -- sometimes you fall off of it!
61-year-old Aerosmith frontman Steven Tyler tried to entertain crowds with a crazy, spinning chicken dance last night in South Dakota -- and ended up flying off the stage.
He was airlifted to a nearby hospital after the fall -- he suffered minor head, neck and shoulder injuries.
Anderson Cooper was outed as a Lady GaGa fan last night -- and the eternally short-shorted Richard Simmons didn't miss a beat challenging him to a "Just Dance" dance-off.
Cooper didn't take the bait, but the 100% authentic awkwardness is just as entertaining ... if not more.
You ever seen a seven foot, 300 lb man bust a move in his bathroom?!
Shaquille O'Neal just posted a video on his Facebook page featuring the Diesel breakin' out some serious moves in front of his customized Superman shower.
It's not like he's got the playoffs to worry about...
The boys of the New Zealand soccer team don't get down on themselves when they lose, they just get down! After losing to Belgium in the first round of the Olympics 0-1, the Oly-Whites (as they're called back home) broke out the Haka -- a traditional Maori war dance teams from NZ usually perform before a match to scare the holy hell out of the other team.
No word on why they decided to bust a move after the loss, but as long as that guy keeps his shirt off -- who really cares?!
Natalie Portman proved she could shake it like a stripper in "Closer." But did her pole dancing skills come in handy when Soulja Boy showed up to TRL to teach her some dance moves? Pop and lock, Padme!
Fearless Natalie didn't back down from the challenge, as Soulja gave her a crash course in crunk.

Blake Lewis isn't this season's "American Idol," but that's no reason not to make fun of him -- and Eric Schwartz aka Smooth-E is up to the idol lampooning tricks again!
Remember the Sanjaya Anthem and how Smooth-E captured the essence of little Sanjy? In this new video, E hilariously transforms into the beat-boxing loser. This video has it all, from battling brides to hamster funerals ... even drinking priests.
Somebody needs to give this guy a show. Smooth-E, not Blake.
TMZ spies were out in force last night for Britney's comeback debut, and it was overheard during the wait for Brit to appear, that many were hoping she wouldn't actually sing -- but lip-sync!
Fans who paid a ridiculous amount of cash for tickets wanted their money's worth -- our spy, who paid $300, said he was ecstatic that Spears did what she does best -- dance -- but he was happier she didn't sing!
"Real fans of Britney know what they're getting, a hot performance, not a singer," said our informant. He also said that although there were definitely a few fans who weren't satisfied with the show, the majority of the crowd LOVED every minute ... all 15 of them!
