Catfight! Nick Jonas vs. Justin Bieber

When Justin Bieber was accused of egging his neighbors' home in Calabasas, CA, on Jan. 9th, the media attacked him including one famous twitter user. Just one day after the incident (which reportedly ended in $20,000 worth of damage), Nick Jonas posted, "Wait... egging is still a thing?" Burn! It's not the first time the two singing sensations have had drama. In July 2013, Nick's brother Joe said, "We never had an interest in doing things like peeing in buckets," just days after a video of Justin doing just that surfaced online. Fighting words!
