Are Shawn's fans mad at Cameron's fans?

An all out twitter war has erupted between Shawn Mendes' and Cameron Dallas' fans! It all started when Taylor Swift brought Shawn on stage and he tweeted, "So thankful!" But Cameron wasn't as excited for his pal. "What about the people that helped you get there?" he commented. After that, Shawn's fans went off on Cam, saying what a bad friend he was. But fans can rest easy. At the TCAs, Shawn and Cameron reunited afterwards and tweeted about how much fun they had together. Drama=over!
