That would be one way to explain the footage seen here, of Dr. Dre and Justin Bieber palling around in the studio together. And then another, perhaps more accurate way to explain it would be that it's an ad for JustBeats, a Justin Bieber–approved sub-line of the Beats by Dre headphone line. We still think Explanation No. 1 has some credence, though. Doesn't it look like Bieber is doing much more than Dre in the clip? He's banging out beats and shilling, and Dre is mostly just wandering around bopping his head. Also, if Bieber were secretly producing Detox, that would explain the endless delays: Bieber is a busy, busy man, with all manner of Disney-approved pancake dates and Willow Smith–featuring world tours to take care of, and if he hasn't had time to chop it up in the lab with Dre until recently, that's understandable. Vulture will investigate further and report back our findings promptly. In the meantime, we leave you with one concrete fact unearthed by the video: Justin Bieber's favorite color is purple.
