Justin Bieber Starts Countdown To 'Heartbreaker'

Song will kick off his 10-week Music Mondays series, culminating in his new 'Believe' documentary.

Forget the 12 days of Christmas. What about the 10 weeks of Bieber? Starting on October 7, Justin Bieber will kick off a series he's calling Music Mondays with the long-awaited single, "Heartbreaker."

The plan calls for a new song to be released at midnight on Sunday in the lead-up to Bieber's upcoming movie. "Sunday Midnight #heartbreaker #MusicMondays #10weeks," Bieber tweeted

on Wednesday.

Back in July, Bieber posted the first line
 of the song on Instagram. "Ooh, 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," he sings on the R&B-influenced track that has a sexy groove. The tease for "Heartbreaker" has been going on for months, including the release of the cover art back in June, which consisted of a crumbling purple heart

He reposted the cover on Wednesday with the message, "Are you ready?" Manager Scooter Braun seconded that emotion, adding later that night, "So it begins ... #Sunday #midnight #10weeks #musicmondays -- expect the unexpected."

Not much is known about the follow-up to 2011's "Never Say Never" movie, but Braun has promised
 that a sequel is coming later this year. "[Justin] gives u some new music in October until December and then a special movie on Christmas," Braun said of the in-the-works documentary on his Believe album. That is, assuming director Jon Chu can finish it in time.
