Is It Hannah? Or Miley? Or Is Neither On Stage?

It was ever so brief, but the use of a body double by Miley Cyrus on her best-selling "Hannah Montana/Miley Cyrus 'Best of Both Worlds' " tour is creating plenty of buzz.

A video posted on YouTube shows the 15-year-old entertainer as "Hannah" dancing onstage with a group of dancers and the Jonas Brothers, also on the tour. During the song, someone ushers her offstage via a trap door. Immediately, another girl, dressed like the character "Hannah" in the same pink trench coat, with blond hair covering her face dances around, runs up the stage set, and then quickly leaves.

While the double is holding a microphone for less than a minute, the girl motions like she is singing. A rep for Miley said the switch was only for costume purposes.

"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," according to statement Friday from the public relations firm PMK.

"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."

Actresses Help Promote V-Day Mission

Jessica Alba and Rosario Dawson were among the celebrities who celebrated the 10th anniversary of V-Day, a global effort to end violence against women and girls.

Alba, who made her stage debut performing Eve Ensler's "The Vagina Monologues," offered a poem at a private luncheon Thursday sponsored by Glamour magazine. Ensler founded V-Day, which now reaches 119 countries and has raised $50 million to increase awareness about violence against women.

"It literally started from one woman's voice ... and it's exponentially grown," said Dawson, 28. "It's about embracing being a female and reclaiming that."

V-Day will celebrate its anniversary with a two-day event at New Orleans' Superdome in April.
