During her wildly popular concerts, Cyrus performs as both herself and her Disney Channel character Hannah Montana.
"To help speed the transition from Hannah to Miley, there is a production element during the performance of 'We Got the Party' incorporating a body double for Miley," a representative said in a statement issued to the Times.
"After Hannah has completed the featured verse on the duet with the Jonas Brothers, a body double appears approximately one to two minutes prior to the end of the song in order to allow Miley to remove the Hannah wig and costume and transform into Miley for her solo set. Other than during this very brief transitional moment in the show, Miley performs live during the entirety of both the Hannah and Miley segments of the concert."
