The 28-year-old half-sister of the singer has criticised those who make fun of her controversial younger sibling, 22, and admitted while she can be a bit of a nutter, she's very down to earth.

She said: "I don't know why people like to tear others down to make themselves feel better. I don't know what it is but, yes, Miley is a huge personality. She's a weirdo, but she's so normal."

Brandi - who also has siblings Noah, 15, Trace, 26, Braison, 21, and Christopher, 23 - revealed she was often teased about her family as a youngster though, as other kids used to make fun of her 'Achy Breaky Heart' singer dad Billy Ray Cyrus.

Asked about the biggest misconception about the family, she told ET Online: "For some reason, people love to hate a Cyrus. I don't know what it is, but I remember when I was a kid, and my dad was at the height of his success, all people wanted to do was make fun of me for it.

"I was like, 'Wait a minute. My dad is the biggest star on the planet and you want to make fun of me?'

"As I'm older now, I look back on that and that's just so insane."
