The Internet is going nuts today for a 5-year-old music video of Kylie and Kendall Jenner lip syncing to Taylor Swift's "Better Than Revenge." The video was uploaded to YouTube in November of 2010, back when the Jenner sisters were the totally unknown daughters of an Olympic gold medalist.

Now that Kylie and Kendall have become successful brands in their own right, the video has resurfaced and gone massively viral. Fans and haters alike are fascinated to see what the teenage sex symbols looked like when they were just 13 and 15. Needless to say, it's making many of their admirers uncomfortable.
