Ariana Grande Debuts New Single, 'Put Your Hearts Up'

It's no secret that we're obsessed with Ariana Grande at HuffPost High School -- and clearly, we're not alone. The Victorious star's much-anticipated first single, "Put Your Hearts Up," debuted on Friday, and her many fans took to Twitter to express their excitement. #BuyPutYourHeartsUp quickly became the number-one trending topic worldwide, and if that wasn't enough reason to celebrate, the singer also reached one million Twitter followers on Saturday.

Ariana said of the new single: “It’s a song that I hope inspires people to put their hearts up and that even the smallest acts of kindness can make the word a better place."

It's also been an exciting week for Ariana's costar Victoria Justice, who released a new music video for the acoustic version of "You're The Reason," featuring Victoria playing the piano on the beach.
