After teasing his new single for months, Justin Bieber finally released the anticipated "Heartbreaker" on Sunday at midnight. The debuted track is his first new single since "Believe: Acoustic" in January and it is a part of his "Music Mondays" series, which he promised his fans to release a new song every Monday for 10 weeks.

The 19-year-old pop star and his former girlfriend, "Come And Get It" singer Selena Gomez, parted ways earlier this year. However, they have been seen together on several occasions since the breakup, and their on-and-off romantic relationship was very visible to the public.

When Justin Bieber fans listened to the new track "Heartbreaker," they knew that the singer was clearly referring his single to his romance and split from Selena Gomez. Also, Bieber is definitely not being so subtle with the song and writes on his Twitter, "It's a song for people going through heartbreak - like I was when I wrote it. It means so much to me to be able to share what I was, and still am, going through, with my fans. I'm very proud of this song and I hope it gives my fans some insight into my heart. -JB"

This time, Justin Bieber is being personal in his music, and refers to his semi-autobiographical song as his "music journals." "These songs are different. These are my #journals," he tweets.

The singer announced the single "Heartbreaker" as an R&B ballad, and it is going to be the lead single from his upcoming album.
