Tulisa 'worried' about 'War Child' success

N-Dubz singer Tulisa has revealed that she is worried illegal downloads may limit the success of new charity song 'I Got Soul' with Young Soul Rebels.

The singer, who joined up with artists including Pixie Lott, Tinchy Stryder and Frankmusik for the War Child track, claimed that young music fans are more likely to access music illegally.

"We are aiming for a younger audience and they tend to download illegally. I don't see what else we can do, apart from kill off Limewire," she told the Daily Star.

Earlier this year, Tulisa admitted that she felt privileged to record the charity track, which aims to raise awareness for children living in war zones.

Young Soul Rebels released 'I Got Soul' today.
