12 Moments That Had You Saying "WTF?" This Year

Out of all the weird things that happened at this year's Billboard Awards, Kendall Jenner's onstage slipup was probably at the top of list. Not only did she commit the cardinal sin of mixing up One Direction and 5 Seconds of Summer, but then she went into a fit of giggles before telling an entire audience of people (and at-home viewers) that she's illiterate. "I'm the worst reader," is not something you want to hear from a person who just recently released a book. It's cool, though: Kendall bounced back from the onstage flub and went on to have one of the best years ever.
