Ariana Grande is generally known as a sweet and slightly reserved pop star. But tonight, in the spirit of Halloween mischief, she’s come to *Dracula voice* suck your blood! The “Break Free” singer posted a cute pic of herself all dolled up in vampire duds (is that red eye or some fierce contact lenses?!) and fangs on Instagram tonight (October 25).

So maybe it’s a few days before the actual holiday, but Ari seems eager to get a jumpstart on her Trick or Treating! Kidding, kidding we all know she’s probably going to be hanging out with her new boo (get it?!) Big Sean. Maybe they’ll go to a party with Kanye and Kim? Now I’m just brainstorming cute couple costumes for all of them.

This seemed to be just a sneak peek of a more complex costume though, as Ari wrote: “Fitted my vampire teeth yesterday. I’m being a very specific kind of vampire lol… you’ll see.” Not quite menacing, but definitely intriguing. Stay tuned until All Hallows Eve to see what Ari has up her sleeve. One more question, will her signature cat ears be involved, because that looks like them in the pic!

Have you checked out Kiesza yet? Cuz you’re going to want to. The Candaian experimental pop singer-and-dancer has been turning Brooklyn into her own personal dance studio since she stepped on the scene of Wythe Avenue earlier this year for the acclaimed “Hideaway” video.

Her sophomore album Sound Of A Woman officially came out earlier this week (October 21), but the singer didn’t rest on her laurels at all, following it up with this new video for “No Enemiesz.” As always, she can’t stop moving, and her moves are just as head-turning as her earlier clips.

But Kiesza also seems unable to stop shedding layers as she dances throughout the loft apartment, stripping down right till the end of the track. There’s a reason this girl was a VMA nominee for best choreography—she knows how to move. Watch for yourself below:

Kim Kardashian turned 34 on Tuesday (October 21) earlier this week, and though she probably won’t top last year’s surprise engagement to Kanye West, she still managed to pull off an enviable party in Las Vegas last night (October 24).

She teased the event a week before on Instagram, revealing that she’d be celebrating at The Venetian hotel’s Tao in Las Vegas:

Then, she snapped a pic of everyone before boarding the plane to get to Vegas:

Last night at the actual party, she had plenty of people to pose with and thank for being part of her tumultuous, fashionable life.

But family first, as always:

Of course she still managed to get some time alone with her husband Kanye:

And pose with her ver-present glam squad

No matter what happens, Kim doesn’t forget her “OG Crew”—and she never apologizes for cleavage:his own personal “happy birthday” to Kim on Twitter as well, and yes, it did include the word “dopest.” Happy birthday Kim! Next year, invite me to come celebrate with you.

“The Walking Dead” is a monstrous franchise, and one of its hydra-like heads is Greg Nicotero. The makeup and visual effects guru is an essential asset of the AMC television show, creating the distinct look and feel of the undead walkers… And he’s branched out into producing and directing, including the incredible season five premiere.

But “Walking Dead” isn’t just on TV and in comics… Nicotero is also bringing the dead to life every day until November 1 at Universal Studios Orlando’s Halloween Horror Nights. The terrifying nighttime attraction features key scenes from the fourth season of the show, as well as some original scares throughout the “maze.”

With Halloween Horror Nights well under way, MTV News got on the phone with Nicotero, as well as Director of Entertainment – Creative Development for NBC/Universal Themeparks Michael Aiello – to talk about what went into bringing the show to literal life… As well as some hints at the “Walking Dead” spinoff, and a possible movie:

MTV News: “The Walking Dead” has been part of Halloween Horror Nights for a couple years now, but Greg, what was it like being involved this time? What touches did you bring from the show?

Greg Nicotero: Well, you know Mike Aiello and I have collaborated pretty well in the last uh, this the what, third year?

Michael Aiello: Third year!

Nicotero: We liked the idea of taking the greatest hits of season four, so while we’re shooting the show we have these highlights… You know, we have the ...

Okay Swifties, you might want to sit down while you read this post because it gets really super personal, romantic and swoon-worthy. We got Taylor’s partner-in-songwriting-crime Jack Antonoff to interview her for us yesterday (October 24) in her now-home of New York City about 1989—and the results are much more intimate and emotional given the close relationship the two already have.

I mean, they’re close enough to act like total goofballs together:

Are you ready for a majorly touching tidbit to be revealed? Good, because it involves Antonoff’s long-time girlfriend and Swiftie pal Lena Dunham, who has already dubbed one of the tracks off 1989 as her “someday wedding song,” but that’s probably because Taylor wrote it about Lena and Jack’s relationship.

“You guys are like the benchmark of actual, real true love,” Taylor tells Jack, who manages to take it all in stride. Watch the two discuss the song below, which Jack wrote the music for and Taylor describes as the sound of “real love.”

While Antonoff was working with Tay Tay on one of the songs off 1989, he didn’t realize that he was closer to the heart of the song than just as a musical collaborator.

For “You Are In Love,” Taylor used the relationship that Jack and Lena Dunham share as her inspiration to get all lovey dovey. But apparently, Lena didn’t even know it was about ...

Lady Gaga decided to take a trip down the jazzy lane this year, and put out an album that went in a totally different direction from ARTPOP with her Tony Bennett collaboration Cheek To Cheek.

The album is jazz standards done by Gaga and Bennett in duets, and you’d think that some of her pop-loving fans might not want to make the transition into jazz, right? Nope. Wrong—monstrously wrong. Instead, the Little Monsters have been losing their minds over the album, and specifically during tonight’s (October 24) special PBS performance of the album.

Gaga herself was obviously stoked about the event, and live-tweeted along with the taped performance:

But she wasn’t the only one—countless fans reflected on how excited they were about the unlikely fact that they were falling in love with jazz.

Even Tony Bennett got into the live-tweeting! He was watching along with his wife Susan and this adorable bundle of fluff named Happy. Uhhh Tony, can I come over and watch with you??

After all that tweeting, the site even went down for a few minutes—something the monsters gladly took responsibility for.

Wanna get in on all that jazz? Get your copy of Cheek to Cheek here, or, if you missed the special you can watch a brief clip of them watching the title track below.

When two male students came dressed up as women to their Washington high school earlier this month—one, as Nicki Minaj, and the other, as Miss America—they were told they had two options: Change outfits, or go home.

They were surprised, since they were following the protocol of the White Pass Jr. Sr. High School Spirit Week, which, on this day, called for students to “dress like a celebrity,” according to KING5 News in Washington. That didn’t stop the principal—whom the boys said told them they needed to change—from trying to lay down the law.

“I asked him why,” Mudge said. “He said, ‘No reason.’”

So given that choice, Chandler Krueger and Mason Mudge decided to leave.

In an inspiring show of solidarity, fellow students came to school the following day dressed in outfits generally associated with the opposite sex.

“I think it’s really awesome that all the kids support me and support the decisions that I made,” Mudge said. “I walked into school this morning and everyone was wearing dress[es] and pink and all that.”

Superintendent Chuck Wyborney seems to agree that the way the two high schoolers were treated was unjust. “If it happens again, we’ll handle it differently,” he said.

What do you think? Was the principal out of line? Would you have protested his decision too? Let us know in the comments.

I bet you weren’t expecting this to start your weekend: A new video from Justin Bieber.

The Biebs joins Khalil in the visuals for “Playtime,” off of Khalil’s A Long Story Short mixtape, which dropped back in August. The video is pretty low key, as the two friends are mostly hanging out, bouncing around outdoors, and are eventually surrounded by a crowd (which, all things considered, was relatively reasonably sized). JB also busts out some dance moves.

Unfortunately, the video caused some tears.

OK, they were tears of joy. Still.

We should probably start getting used to hearing new music from Justin. Last week, he remixed Meghan Trainor’s “All About That Bass” and told manager Scooter Braun that it’s “time to go back to work.”

Here we go.

Clearly, every day of the week should be a celebration of all that is Britney Spears, but the good people of Las Vegas have finally made this into a reality. The City of Lights has dedicated November 5 to Brit in recognition of her impact on the city since her residency began there in December of 2013. Britney was just as excited about the announcement of “Britney Day” as we are, tweeting about how honored she felt:

Yes, it is an honor, but we are also expecting on “Britney Day” that our beloved Britney Jean will be working it, bitch! Here’s a rundown of what the day will probably look like:

Clark County Commission Chairman Steve Sisolak will give Britney an an official proclamation, declaring it her day in a bunch of legal jargon.

Sisolak will also hook Britney up with a key to the city of Las Vegas! Which, if you think about it literally, presents endless possibilities…

Britney will completely take over The LINQ Promenade and hang out with her fans — especially fellow Britneys! The first 100 will get a free pair of tickets to her concert at the Planet Hollywood Resort & Casino that night.

But if your name isn’t Britney don’t worry, you can still purchase tickets to see “Britney: Piece Of Me” performed that night.

You can get even more details about the first ever “Britney Day” via her website. Until then, we’ll be rocking out to ...

Taylor Swift isn’t really afraid to lay it all bare via the singable diary entries that are her songs. Yup, when it comes to her business, she’s as open as, well, a business on a weekday.

Still, we Swifties will not be sated until we understand every facet of her bubbly kitten-crammed personality. We want to breathe ourselves into her beautiful soul, basically, and we will not rest until we do.

So MTV News hit up forensic document examiner and handwriting expert Dianne Peterson who took a look at all those handwritten 1989 lyrics Tay has been posting (assuming she penned them herself), and asked her to tell us what she could glean from all that ink.

I don’t know about you, but I feel closer to Taylor already, guys. But maybe that’s because I’m wearing a vintage nightgown, drinking a Diet Coke and squeezing a kitten while writing this.

But I digress… Read on:

1. She’s Honest

“Taylor has open O’s — this means she is an honest person.”

2. She’s A Good Listener

“The eyelets of her lower case ‘e’s and ‘a’s are open, which means she is a good listener.”

3. She’s Sassy

“The cross bar of her ‘t’s are pointed on one end, which means she can be sarcastic and may have a sharp tongue at times.”
