Madonna surprised school children in Kent, south-east England on Friday when she turned up to a charity fundraiser unannounced.
The Material Girl shocked pupils as she arrived at the New School festival in Sevenoaks in a helicopter - as a favour to business tycoon Mohamed Al Fayed.
The Harrods boss, who is patron of the underprivileged children's centre in the town, invited Madonna onstage, introducing her to the crowd as the "biggest superstar in the world".
Al Fayed tried to get the singer to perform a duet with him, but she insisted, "I haven't done my vocal warm-up."
