Alicia Keys is looking for a new back-up singer in cyberspace. The hitmaker is asking wannabes to "audition" to be a part of her touring group via her MySpace website.

But hopefuls, aged between 21 and 30, have to act quick - the internet audition ends on Monday. Keys wants singers to submit a 30-second video featuring themselves singing a cappella.

She asks that all candidates are "physically fit and able to dance."
