Listen to Justin Bieber New Song 'Heartbreaker'

Justin Bieber released his first new song in a long time, Heartbreaker, Us Weekly reported.

"Heartbreaker," is said to be about Selena Gomez. Bieber and Gomez have parted ways earlier this year.

The song is part of the singer's Music Monday stunt. It is where Bieber will release a new song every Monday for 10 weeks.

"These songs are different," the Great Wall of China-climbing phenom tweeted. "These are my #journals."

The song "Heartbreaker" is semi-autobiographical, Bieber claimed. "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."
