Ariana Grande's Wicked Performance Sparks Lip-Sync Debate.

The first official clip of Ariana Grande performing as Glinda in the upcoming movie musical adaptation of Wicked has sparked debate about whether she is lip-synching to her own track or a recording of Broadway's original Glinda, Kristen Chenoweth. Lip-synching is standard practice for movie musicals, but the video's YouTube comments reflect some disagreement. However, the film is still over a year away, and there is no indication that Grande won't sing her parts. Director John M. Chu has promised more teasers to come.
