Cyrus, who wrote "Malibu" for her boyfriend, choked up while singing the last verse of the song.

“I never would’ve believed you if three years ago you told me I’d be here writing this song,” she said in an interview with Billboard earlier this month. “They’re going to talk about me if I come out of a restaurant with Liam. So why not put the power back in my relationship and say, ‘This is how I feel’?” 

Cyrus later changed into a white ruffled ensemble to watch the rest of the awards show with her family.
