Miley's sister will always have a soft spot for her former fiance!

Brandi Cyrus talked to ET's Katie Krause about her new horror film, Old 37, but took a moment to address Liam Hemsworth's recent interview, where the Hunger Games star said he will always have feelings for Miley.

"They were together so long," says Brandi. "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 adds, saying that Miley wouldn't mind his comments, because, "She's not bothered by much, to be honest."

"That has to make you feel good when somebody that you know, haven’t talked to in a while, comes out and says that," notes Brandi. "It's very mature."

"I mean, look -- we were together five years, so I don't think those feelings will ever change," Liam, 25, told Men's Fitness in October. "And that’s good because that proves to me that it was real."

"You fall in love with who you fall in love with; you can never choose," he explained.

Meanwhile, Brandi's horror role is basically old hat for the actress, who reveals that her dad, Billy Ray Cyrus, used to make his children watch horror flicks!

"When I was a kid my dad forced us to watch scary movies," Brandi says. "I was forced to watch The Shining, and he was like, 'This is the best movie ever made, and you’re going to watch it.'"

However, the scare factor was the least of Brandi's problems while filming Old 37. The actress tells ET that she actually had to lie down on concrete covered in fake blood while filming the movie.

"Literally, I don’t think I’ve ever been so cold in my whole entire life," she says. "When my mom's like, 'I'm cold,' I'm like, 'YOU DON'T KNOW COLD.'"

"You’re drenched in wet fake blood --like it could not have been worse -- and then to top it off, you’re dead."

Brandi credits making it through the experience to that Cyrus family work grind.

"Both [Miley and Billy Ray's] work ethics on set are so awesome to watch," she explains. "Having seen that, I’m here and I’m freezing, but I’m making a movie, so, I’m going to be a trouper."
