If Justin Bieber is an alien, there's a good chance that the Jonas Brothers are too. Like Bieber, this group seemingly appeared out of nowhere and landed - possibly literally - at the top of the charts. They've also grown an enormous fan base of teenage girls who are willing to attend their concerts, buy their merchandise and listen to their music, nonstop.
These amazingly-close brothers seem to have a power over their fans that is hard to replicate. Perhaps that power is not of this Earth. A Men in Black cameo could show the world that they're not exactly a typical boy band.
