Justin Bieber filming 'All That Matters' music video: second Music Mondays single will get official visual in coming weeks [PHOTO]

Justin Bieber isn't just continuing his Believe Tour in South America, the "PYD" singer is also busy shooting a music video. Seven weeks into his Music Mondays series, one of the tracks is finally getting the official video treatment. What song will be getting a sizzling Bieberlicious video treatment? The answer is none other than song number two: "All That Matters."

Bieber announced that "All That Matters" would be receiving a music video on his official Twitter account earlier this week. While Bieber didn't initially announce which Music Mondays single would be receiving the clip, eventually he confirmed the news. "video shoot #journals #AllThatMatters," he wrote simply yesterday (Nov. 17).

Bieber then confirmed the news further in multiple day posts on Twitter and Instagram, wherein he posed with a happy bunch of Beliebers outside the video shoot.

Not only is Bieber shooting a video for "All That Matters," but he's actively pushing it as the first Music Mondays single, asking fans to request the song on radio and continue to purchase it.

The push for "All That Matters" as opposed to "Heartbreaker" is an interesting decision for Bieber and his camp. While "Heartbreaker" was the most highly anticipated track from the project, with months and months worth of relentless teasers from Bieber, "All That Matters" was released almost as quickly as its title was announced.

"All That Matters" has, however, been the second most successful Music Mondays single (first, of course, is "Heartbreaker"). In a recent analysis from Billboard.com, it was revealed that "All That Matters" sold 127,000 copies in its debut week, and it reached No. 24 on the Hot 100, after dropping off after one week. In comparison, "Heartbreaker" debuted at No. 13 and stuck around on the chart for two weeks.

There is no official release date for the "All That Matters" music video, and other details about the clip are scarce.
