Brandi Cyrus Opens Up About Family Rumors: 'People Love to Hate a Cyrus'

Brandi Cyrus is sticking up for her sister Miley Cyrus.

ET caught up with the 28-year-old actress to talk about her new horror film, Old 37, and during the interview, we played a fact or fiction game with her to help clear up some of the outlandish headlines involving her famous family.

Before the game began, we asked Brandi our biggest burning question: "What is the biggest misconception of the Cyrus family?"

"For some reason, people love to hate a Cyrus," Brandi said, laughing. "I don't know what it is, but I remember when I was a kid, and my dad [Billy Ray Cyrus] was at the height of his success, all people wanted to do was make fun of me for it," she explained. "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," she continued. "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."

ET kicked off the game by asking her whether or not her sister, Miley, is on a mission to date Kristen Stewart, after Miley called the Twilight actress "hot" on Instagram.

"Oh my gosh. I mean Kristen Stewart's hot, don't get me wrong, but fiction," she quickly answered.

"Are you serious? Meanwhile we're all having a pajama party, eating popcorn in our unicorn onesies," Brandi said.

Another untrue headline? Miley reportedly hooking up with 43-year-old comedian Dane Cook. "That's so fiction, but we are great friends with him."

Brandi's 15-year-old sister, Noah, has also made headlines recently for hanging out with Keeping Up With the Kardashians star Kylie Jenner. When asked if Noah was encouraged by her dad to go "clubbing and partying" with Kylie, as some reports claim, Brandi quickly shot the rumor down.

"OK, this is hilarious. Literally for weeks we laughed about this being a thing," she said. "So Noah and I would be sitting around like 10 o'clock on a Friday night in our PJs, and Noah would be like, 'Bran, take me to the clubs. They can't keep me out of the clubs.' And we'd tweet stuff like, '@TishCyrus can't keep me out of the clubs.'"

"It was a running joke for the longest time because it's just… I mean, people only knew," she added. "Noah just sits at home in her PJs."

Glad that's all cleared up!

ET also chatted with Brandi about her thoughts on Liam Hemsworth's recent interview with Men's Fitness, where he revealed he will always have feelings for his ex-fiancée, Miley. The two started dating after they met on the set of their romantic film, The Last Song, in 2010, and were together until they called off their engagement in Sept. 2013.

"They were together so long," Brandi explains. "For me, exes, they're like family... They're always gonna be like family."

"That's really cool that he said that, you know?" she added. "She's not bothered by much, to be honest."
