What: The glamour puss was putting her powerful pipes to work, belting out God Save The Queen while wowing in a nude-coloured bandage dress and killer heels that would have made us more nervous than the singing itself.
Where: The NFL International Series match between the New England Patriots and the St.Louis Rams at Wembley Stadium.
Verdict? She looks fab, but aren't bandage dresses, like, so last year (or five?)
