Demi Lovato performed her hit single "Cool for the Summer" with Australian rapper Iggy Azalea.
Justin Bieber performed both his latest single, "What Do You Mean" and "Where Are U Now." The artist appeared to get emotional at the end of his performance after thanking the audience.
Recap of the night's biggest moments: Perhaps the most talked about moment came when Kanye West went onstage to accept his video vanguard award. The 38-year-old rapper then criticized MTV for exploiting artists and said he would be running for president in 2020.
Swift's face after perfectly summed up viewers response to West's speech:
Cyrus' fashion certainly caught the attention of viewers, too. The former Disney Channel star, known for her outlandish and at times revealing fashion choices, made several wardrobe changes throughout the night.
The most tense moment of the VMAs came when Minaj called out Cyrus for recently taking aim at the "Anaconda" singer in the press.
When accepting her award for best hip hop video, Minaj turned to Cyrus and said, "Back to this bitch that had a lot to say about me the other day in the press. Miley, what's good?"
The night ended with a surprise performance by Cyrus herself. The artist made an unexpected announcement that her new album was available online.
