Britney Spears' manager has defended the pop star for lip-syncing on stage, insisting all the best female singers use a backing track in concert.
Spears is currently preparing for a two-year residency in Las Vegas but many fans fear they will be short-changed unless she ditches her miming and sings live.
Her manager Larry Rudolph has now spoken out to address the criticism, insisting the Toxic singer will go live in Sin City - with the aid of a backing track.
He tells Billboard.com, "It's hard for the public to understand what goes on when you get on stage and you're dancing full out during a song. No matter what anyone says, there's not a single artist who goes out there and does full choreography and is singing without a vocal track underneath them... It's physically impossible... There might be some numbers where she's full out dancing with a (vocal) track underneath her, but there won't be any lip-syncing across the board."
Rudolph also addressed reports that Britney is attending singing lessons ahead of her residency, adding, "The vocal coaching is really just to strengthen her voice and get her to a point where she can go out there every night and do a full show."
