Watch Justin Bieber Get Down In Mysterious Dance Rehearsal Vid

Amid his legal troubles, Bieber took time out on Sunday to practice dance moves.

These days, Justin Bieber spends more time rolling his eyes and sighing through four-hour depositions
 than he does rocking the stage, but on Sunday he got back to work on his day job: music.

In a video from a dance studio, Bieber and an unidentified male practice a slow-motion pop lock routine to "Hold Tight,"
 one of the songs from his recent #MusicMondays series. Moving their bodies in perfect unison, at one point the pair reach out their arms and grab an invisible dance partner around the waist to bring her in closer.

Considering his recent public drama, it's clear Bieber was looking for some privacy during the rehearsal, since the window into the studio is covered over with brown butcher paper.

It's unclear what Justin is practicing his steps for, since as of Monday (March 10), there were no tour dates or public appearances on his schedule and it was unknown when he would release the fruits of his recorded labors with T-Pain

Bieber's most recent collection, the online-only Journals was a sales disappointment and at press time his tour film "Believe" had grossed just over $6 million, or $70 million less than 2011's "Never Say Never."

Back in December, Bieber said that he was considering "retirement"
 from the music biz, a claim his camp later said was made in jest. According to a recent Rolling Stone cover story on the singer's streak of rebellious behavior and legal problems, though, a source close to his camp said, "his schedule has been cleared for the foreseeable future so that he can work through his phase."
