These Mariah Carey super fans got a whole lot more than they bargained for Tuesday night..

Jimmy Fallon invited a bunch of “lambs” onto his Late Night show to hear Carey’s new song, Art of Letting Go, then surprised them with a live performance by the great Mariah herself—and Popdust has video.

Not surprisingly, the fans totally lost their shit….

Screams, tears and much joy ensues….

Who doesn't love a little Mimi?

We've long been big fans of "Bound 2," the conspicuously sunny and non-industrial-sounding closer to Kanye West's latest masterwork Yeezus, and the one song on the album we wouldn't be absolutely terrified to play in mixed company. Of course, the song is still far too weird to work as a single--there's no actual beat to speak of, there are unexpected mid-song diversions that cut back just as jarringly as they cut in, and the whole thing ends on an extended reference to the '90s sitcom Martin.

But the core of a crowd-pleasing jam is more or less there, and was brought out last night during Kanye's live performance debut of the song on Late Night with Jimmy Fallon. The Roots were there, of course, as was Charlie Wilson, and a bunch of kids up way past their bedtime (but not really). We loved it, of course, and here are seven reasons why:

1. Intro! Unlike the album version, which launches you directly into the "Booouuuuund to fall iiiin loooooove..." sample, this live version starts with a nice piano intro, with Wilson singing his "I know you're tired of loving..." hook from the song's out-of-nowhere bridge, before the song kicks in proper. It makes Uncle Charlie's later interruptions seem more coherent, more an inextricable part of the song, rather than an accidental tape splice or what have you.

2. "SHABBA-DABBA-DEE-DWEET-TWEET!!" Normally in "Bound 2," Wilson's contributions are kept to the aforementioned bridges, but in a a live setting, he's gotta stand around for the whole song anyway, so he may as well throw in some interjections here and there. Perhaps this jabbering is a live trademark of Uncle Charlie's, but it sounds kind of random and hilarious to us, especially when he repeats it enough times to make it clear that it's not totally improvised.

3. Return of the 12-12-12 kilt! Quickly becoming a live staple of Yeezy's, the leather kilt that made for one of the ten most confounding parts of Kanye's banzai performance at the Concern for Hurricane Sandy Relief at MSG last year made another appearance on Fallon last night, along with a denim jacket that 'Ye kept almost-but-not-quite taking off, like he really wanted to show off how fit his shoulders were looking these days. Sure.

4. Ray J burrrrrrrrnnnnn. Because apparently you can't do a Fallon debut performance without changing song lyrics to take shots at celebrity rivals, Yeezy tinkered with his opening line to "Bound 2" ("All them other niggas lame and you know it now") to take out his wife's ex ("Brandy's little sister lame and he know it now"). Unnecessary, of course, but it's good to see that fatherhood hasn't matured Kanye too much.

5. Gibb & Gibb & Gibb.

Nice call, Questlove. We're sure the boss approves.

6. The band pausing every time for the "Uh huh, honey" sample. Still gets us every time. Why not get Brenda Lee herself to do it live next time, though? Maybe even let her do a couple bars of "Sweet Nothins" while she's at it. She's not even 70 yet, incredibly enough.

7. Outro! We never thought "Jerome's in the house, watch yo' mouth" would make for such an incredibly unifying and cathartic ending sentiment, but with the kids and the band and an almost-almost-shirtless Kanye and everything, it's a pretty righteous finish. Can't wait to see Kanye and company take this show on the road.

In her first-ever U.S. televised performance, Sky Ferreira made her debut on Late Night With Jimmy Fallon Monday night.  Backed by the instrumentation of The Roots, the bleached blond performed cult hit “Everything is Embarrassing” with as much intensity and strength as we’ve come to expect from the singer.

Check it out:

With its quiet melody and nod to early 80s pop, “Everything Is Embarrassing” made several 2012 hit lists including New York Magazine’s song of the year. Ferreira also recently released the video for track “Lost in My Bedroom” off of her LP Ghost. In it you see an artfully disheveled Ferreira in a home-movie styled video.  We love the fact that it came with a warning label indicating people with epilepsy shouldn’t watch.

Mariah Carey is the latest superstar to be welcomed into Jimmy Fallon's late-night music room, bringing early holiday cheer via her legendary "All I Want for Christmas Is You" and a supporting cast of children's instruments, helmed by Fallon and The Roots. Following Carly Rae Jepsen and Christina Aguilera's similar performances with toy drums and school supplies, Mimi and her flock of men reimagined the 1994 track with tiny xylophones. Fallon's adorable Christmas sweater, the kazoo and Carey's vocals all help to redeem the song you love to belt after one too many eggnogs following last year's strange and displeasing Justing Bieber revamp. (We're still scratching our heads on that one.)

But the best thing? The regal Mimi—sitting legs crossed, sans instrument—draped in red fabrics, waving her finger around like this is the original installment of Divas Live.

Can you believe the original came out almost 20 years ago?

Nelly was on Late Night with Jimmy Fallon last night, not looking to address his haters by turning their disrespectful messages into comedy, but rather to promote his latest Joe Jonas-assisted endeavor, The Next. Of course we briefly forgot about his upcoming dive into televised judging in lieu of his recent Chris Brown collaboration "Marry Go Round," a brief taste of what to expect of the forthcoming M.O., and our secret wish to be transported back to the time when "Ride Wit Me" was all you heard on any radio station. But it is summer, so we've accepted the fact that everyone wants to talk about bad reality television or the best home cooling methods, yet it's difficult to watch Nelly chatting on a couch with out having the expectation of a performance. Where's Kelly Rowland hiding? Ashanti? Tim McGraw?!

Luckily that wily rascal Jimmy Fallon is always on the same page as we are (reason No. 867 why we love him). After the teeniest bit of pleading—don't you think for a second that Fallon's assistants don't stock his set with all the necessities for an impromptu performance—Nelly made his way to the stage, having replaced the signature cheek band-aid with thick clear rims the players of Team USA will no doubt be rocking in two week's time. Because today's children should live through sweltering months without a hip-hop anthem providing instructions on how to take all that sweat and discomfort and channel it into sexual energy, we were treated to a vintage performance of 2002's "Hot in Herre."

It's already clear that The Roots make everyone sound good, but this is hot... shit—sorry, we got our classics mixed up for a second. Can "Throwbacks with Nelly" be a weekly feature on Fallon's program? It's only fair if he insists on doing this reality show. Plus, his catalog is deeper than one might think. Watch below.

Before we venture too far into the details of Frank Ocean's promotional schedule, a word on just that. There have been approximately 6,312,598 words--this is an official total that you are very free to cite--written in the two days since Ocean posted his liner notes about falling in love with a man. Some of them have implied that Ocean's post was a publicity stunt. The thing is, though, Frank Ocean didn't need a publicity stunt. Channel Orange was already one of the most anticipated albums of the year, in circles both critical and commercial. "Novacane" and "Swim Good" both charted respectably, which is remarkable for an album (Nostalgia, Ultra) that started out as a self-released mixtape and never got an official release. "Thinking About You," more sanctioned a release, charted as well. In the past year alone--before his album was even out--Ocean had written for Beyonce, appeared multiple times on Watch the Throne when nobody else did and gotten heavily promoted during the BET Awards just days before the announcement. He'd just dropped a 10-minute prog&B track, "Pyramids," which was heavily praised. Basically everything he did, in fact, was heavily praised, even by those opposed to Odd Future. You'd have to be astonishingly jaded to read Ocean's post, note its vulnerability and deem it cynical even if it were plausible, but in this case, it isn't even that.

Anyway. On to the news, starting with:

"LATE NIGHT WITH JIMMY FALLON"

Ocean will appear Monday on Late Night with Jimmy Fallon. It'll be his network television debut, though Fallon did host Odd Future in 2011. No word on what he'll perform, but presumably he'll be backed by The Roots. And if we can make backseat suggestions, one track that'd sound fantastic with them might be...

"SWEET LIFE"

Today, Ocean also posted one of the Channel Orange tracks, "Sweet Life," on his site. For those following along with the avalanches of verbiage written about Frank Ocean and/or Odd Future in the past couple days, this is the track that says "My TV ain't HD / that's too real". It's not clear whether it'll be a single.
