OK! magazine is reporting that Hannah Montana/Miley Cyrus uses a body double during her concerts.

The fake Miley can be seen in the video above at about the 2:17 mark when the real singer is ushered through a side door during the song "We Got the Party" as the fake dashes out to cover her for a costume change. The fake Miley finishes the rest of the song lip-syncing and dancing on risers.

This clip also indicates that Miley is lip-syncing, as her vocals continue throughout the cast change.

"The whole time this was happening Miley's vocals were still playing. The new imposter had her back turned while she danced, trying to hide that fact that she was not Miley Cyrus," said one fan. "At this instant I became very suspicious. ... I paid good money to see the concert. I was disappointed and I felt like I was played for a fool."

The singer's reps say Miley does this to turn from Hannah back into herself via a quick costume change. No comment on what kind of idiots need to be fooled into thinking Hannah Montana and Miley Cyrus are two different people though.
