The singer was left 'terrified' by the ordeal and thanked London’s Metropolitan Police for foiling the plot as she co-hosted the GQ Men of the Year awards last night (02.09.08).
Lily, who shared presenting duties with Sir Elton John, said: 'My friend Charlie was kidnapped a few weeks ago and was kept in a car boot for six days without any food or anything. It was really scary.
