Miley Cyrus once donned a wig in an attempt to go undercover like her onscreen alter ego HANNAH MONTANA - but her plan was foiled when she set her hair on fire.
The Disney star shot to fame on her hit Disney TV series, in which she plays Hannah Montana, a pop star who wears a wig onstage to conceal her true identity as school student Miley Stewart.
Cyrus attempted a similar stunt to go unnoticed by her fans - but her efforts failed when she used a straightening iron on the hairpiece.
She tells British talk show This Morning, "I had the idea (to go out in disguise) so I got a wig and it was really short, a tomboy cut, and I decided to straighten it. I'm sitting down and all of a sudden I start smelling smoke. I thought, 'What is that?'
"The wig is literally catching on fire because I didn't know it was a cheap wig. And I thought, 'This isn't going to work for me.' So it doesn't work in real life but it works on the show!"
