Reports say 22-year-old Natasha's computer was taken on 2 September at Heathrow Airport, but no-one has been arrested for the crime yet.

As well as new songs, the computer also contained unfinished versions of tracks from her number one album Unwritten.

Natasha topped the albums charts after spending three weeks at number one in the singles charts with These Words.

It's thought the computer was taken from her suitcase as she was returning from holiday.
