In one of the night's upsets, Tris, played by Shailene Woodley in "Divergent, won favorite character of the year, coming from behind in last-minute voting to surpass Lawrence's Katniss. They each received more than 9 million votes.

O'Brien, 50 years old and noticeably older than most award winners and audience members, kicked off the show by trying to break the record for the most celebrity cameos in his intro, notching up 50. Among them were Taylor Swift, who gave him a manicure, and Internet sensation Grumpy Cat, who slept in the front row of the audience.
