1. Sparkles on sparkles on sparkles.
From her amazing black sequin dress to her ear piece, Ariana Grande had no shortage of glitz during her performance.
2. Her signature cat ears made an appearance (because who doesn't like a good cat ear?) MEOW!
3. We've never seen so many grown men cry during a performance. Hey, dudes can be Arianators too!
4. Childish Gambino joined Ariana on-stage to perform their hit song "Break Your Heart Right Back." Who's ready for his new mixtape to drop? **raises hand**
5. Twins for back-up dancers. Everything is better in twos!
6. It's no secret that Ariana can hit the high notes but seeing her do it live is on another level. Girl can sing!
