Ariana Grande's "Focus" single was the talk of the Internet town when the song and video first premiered on Thursday night (Oct. 29), and one day later, the pop star debut the song live at an iHeartRadio event in Los Angeles. 

The "Problem" star got into the Halloween spirit but showing off some choreography among fake tombstones and skeleton backup dancers. The haunted-house vibe is starkly different from the official video for "Focus," but leave it to Ariana to keep her fans on their toes.

"Focus" precedes Grande's third studio album, Moonlight, due out in 2016. The singer will also appear on a remix of Justin Bieber's "What Do You Mean?" that will be included on his forthcoming album, Purpose.
