What Does Miley Cyrus Fear?

Suffers From: Acrophobia (fear of heights)

Miley Cyrus is not a timid gal. She's always trying new things with her style and most notably, her hair. So, does anything scare Cyrus? Apparently heights!

Talking about her flick 'So Undercover,' Cyrus told Digital Spy, "In the opening scene, I'm dangling off the side of a building in New Orleans which is 100% real. I am so scared of heights. Going up an escalator freaks me out!" Let's hope she and Nicki Minaj never go to a mall together!

While filming the scene, Cyrus said her dad was absolutely having an achy-breaky heart attack."My dad .... was like, 'No, you can't do this!' I was literally walking on the side of the building, which is one of the craziest things I've ever done," she said.
