It's been a while since Justin Bieber dropped his "Heartbreaker" sampler on his Instagram last July, but now Beliebers will finally get to hear the song in full when it gets released on October 6 at midnight. The much-awaited debut is part of a new project by the 19-year-old pop superstar where he will release a new song every Sunday at midnight for 10 weeks in a series tagged as "Music Mondays."

"Sunday Midnight #heartbreaker #MusicMondays #10weeks," the "Beauty and a Beat" singer announced on Wednesday, October 2 on Twitter. He also re-posted on Instagram the purple heart "Heartbreaker" single artwork he first unveiled back in June.

Bieber's Twitter profile also carried news of the series plus a loving message to his Beliebers that read, "#MusicMondays is about to begin - SO MUCH LOVE FOR THE FANS...you are always there for me and I will always be there for you. MUCH LOVE. Thanks." His manager Scooter Braun likewise got in on the action, tweeting, "So it begins.... #sunday #midnight #10weeks #musicmondays -expect the unexpected."

"Music Mondays" is expected to be the lead-up to Bieber's "Believe 3D" movie, the Jon M. Chu-directed feature slated as his follow-up to the high-grossing "Justin Bieber: Never Say Never". The 10-week release series most likely will also usher in a new album from the artist come 2014, his fourth studio album after the chart-topping "Believe".
