Singer Madonna surprised 400 fans at the 25th anniversary screening of 1991 documentary film “Madonna: Truth or Dare”.

Madonna made an appearance at a screening of the documentary at the Museum of Modern Art here on Wednesday.

“She came out to support Alek Keshishian, her longtime friend and director of the celebrated documentary,” quoted a source as saying.

Dressed in a red off-the-shoulder dress, Madonna interacted with her fans during her surprise visit.

“Madonna: Truth or Dare” was originally released in May 1991 and followed Madonna’s successful 57-show Blond Ambition World Tour across the globe.
