Miley then returned to the stage for an impassioned performance of Wrecking Ball, which won her the Best Video award.
Her pal Katy Perry scooped the award for Best Female and performed her new track Unconditionally, while and absent Justin Bieber was named Best Male for the second year in a row. He accepted his award via a video link from South America, where he is currently on tour.
Other performance highlights came from Kings Of Leon, The Killers, Icona Pop, Robin Thicke, Snoop Dogg, Katy Perry and Bruno Mars.
