 The New York Daily News has new details about her VMA performance with illusionist Criss Angel.

Angel will guide Spears in and out of a series of mirrors, making it seem as though she vanishes and then reappears several times, a source told the Daily News yesterday.

Other dancers in the complicated number are being called upon to harness up for simulated flight, the source said.
