Aside from Selena Gomez's peroxide blonde hair, and the fact that Taylor Swift made an appearance... one memorable moment was when Lea Michele screwed up Nick Jonas' name as he took to the stage to perform.
Oh boy.
Introducing Nick to sing his single "Find Out", Lea accidentally called Nick, "Chris."
We think she can be forgiven though, as she was hosting with Chris Hardwick, and what people think happened is that the teleprompter said his name instead.
It's best just to laugh this one off for the silly mistake it was.
