Justin Bieber is teasing fans with a short preview of his upcoming single "Heartbreaker." 

On Monday, the pop star linked his 40 million Twitter followers to a new commercial for his recently-launched fragrance called The Key, which featured the preview.  Earlier in the day, the Biebs tweeted:

Currently on the second U.S. leg of his "Believe" tour, the singer has tweeted that he's expecting to drop "Heartbreaker" "very soon."  He's even suggested that the track is about his former girlfriend Selena Gomez, using the word "heartbreaker" to caption a photo of Selena on Instagram earlier this month. 

"Heartbreaker" will be the first new music from the star since he released "Believe Acoustic" in January.
