Most and all is not different if you research (beyond YOURE CONSTANT GOOGLING) you will find that she did lip sync. I don't care whether Miley lip syncthe issue is that she lip sync during one performance and performed it during another. Under the lip sync article SO MANY OTHER ARTISTS are exposed as to  be lip syncing (WITHOUT SOURCES) so it hold that she lip sync during the parade.

Miley did not lip sync in the Macy Parade in 2009 in any case because SHE WAS NOTO PERFORMING.
