Ethan Miller/Getty ImagesJustin Bieber is such a tease.
During the wee hours of the morning, the 19-year-old pop star tweeted "yeah i just did that," then linked to an Instagram video (see below) and wrote, "me singing first line of #heartbreaker."
Sure enough, he gave Beliebers a taste of his upcoming single by crooning a bit of the track.
"Oh girl, I got a secret place that we can go/'cause girl I really want to be alone/And baby, nobody else gotta know," Bieber can be heard crooning in the quick clip.
Earlier this week, the backing track of the song could be heard in a newly released ad for his fragrance, The Key. The promo comes on the heels of a video teaser for the scent, which hit department stores this month.
No word yet when "Heartbreaker" will drop, but Bieber did tweet on July 14 that it will be "soon....very soon."
