Did Khloe and Kylie fight on the red carpet?

When Kendall and Kylie Jenner presented alongside Khloe Kardashian at the 2014 AMAs, everything seemed fine. Secretly, however, two of the sisters were having a major fight! A source claims it all started on the red carpet when "Khloe mocked Kylie's lips and told her to 'relax the mega pout." Even as they took the stage, Kylie still wasn't over the insult! "Kylie stormed off, saying she didn't want to share a stage with Khloe," the source continues. Yikes!
