Madonna: Truth or Dare turns 25!

Madonna surprised 400 unsuspecting fans that were in attendance at the anniversary screening of Madonna: Truth or Dare at the Museum of Modern Art in New York City on Wednesday.

“She came out to support Alek Keshishian, her longtime friend and director of the celebrated documentary,” a source tells PEOPLE.
Dressed in a red off-the-shoulder dress, Madge appeared to be all smiles as she interacted with her fans.

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

August has been a month of celebration for the superstar.
Madonna recently returned from a birthday trip to Cuba with her children, including estranged son Rocco. The mother of four turned 58 on Aug. 16.
