Just like the first two movies, "" will feature a host of celebrity cameos, including who will appear as an alien. Weighing in on Bieber's appearance in the action comedy film, director Barry Sonnenfeld explained why the pop sensation is perfect to play an extraterrestrial being.
Speaking to Vulture, Sonnenfeld said, "This will get me into trouble, but my theory behind Justin Bieber is that he's from Canada." The filmmaker then explained a larger theory about aliens in Canada which sent spies to the United States. However, when those aliens tried to transmit the data back to their home planets, "3 percent of it got scrambled in the transmission" so they got the wrong coordinates and ended up living in Canada instead.
