So there was a thread about Ariana's next single, but I think I've found something that pretty much confirms "Break Free" is indeed Ariana's next single from her sophomore album.
http://twitter.com/ArianaGrande/favorites scroll dow a bit and see what tweets she has favorited. Two fans replied to Ariana's #BreakFree tweet with tweets: "Is this the title" and "Release the SINGLE" and she favorited those tweets.
Plus she shot a music video and hinted it to be alien inspired (check her Instagram), and Zedd (rumored BF producer, already confirmed as one of Ariana's current producers) replied to her #BreakFree tweet with an alien emoji.
According to
http://josepvinaixa.com, the single is set to be released in July.
Another summer anthem.
