Justin Bieber 'Heartbreaker:' Instagram Video from 'Baby' Singer Reveals Lyrics to First Line of New Single 2013, Release Date Seems Imminent [LISTEN]

It seems as though the release date of Justin Bieber's new single 2013 "Heartbreaker" is getting closer and closer. The teases for the song keep revealing bigger details. After releasing the promo for his new scent The Key earlier this week with the backing track to "Heartbreaker," Bieber took to his Instagram and sang the first few lines of his new, revealing single in the wee hours of the morning.

At 3:18 a.m. (July 19), Bieber slyly tweeted "yeah i just did that," with a link to his Instagram. The short video features the "Boyfriend" singer in a nearly pitch-black room singing the first few lines to "Heartbreaker" a capella.

"Oh girl, I got a secret place that we can go, / Cause girl I really want to be alone, / And baby, nobody else got to know, / Just meet me..." Bieber crooned in an up-and-down melody.

There's no doubt that these are the first few lines of "Heartbreaker," as Bieber explicitly said so in the Instagram video posting.
