The 2015 Billboard Music Awards are in the books.
Yes, Taylor Swift dominated the podium, taking home nearly every award for which she was nominated.
But the superstar did not actually perform at the event, aside from opening the ceremony with her wildly anticipated Bad Blood video.
Who did take to the stage? Such huge names as Mariah Carey, Kanye West, Nicki Minaj and Kelly Clarkson.
One was memorable for being off-key; another for getting censored; another for wearing very little clothing; and another for being totally awesome.
