Catfight! Brandi Cyrus vs. Taylor Swift

When Taylor Swift was given the huge honor of Artist of the Year at the 2013 AMAs, the whole crowd erupted into applause and got their feet to congratulate the singer minus one notable person. Miley Cyrus' sister Brandi stayed seated while everyone (including her father Billy Ray!) stood up. But Taylor has no bad blood against the Cyrus family! In fact, she started her acceptance speech by complimenting Miley. "i'm out of breath, I was going hard during "Wrecking Ball," she laughed. Way to keep it classy, Taylor!
