A Secret Affair is a 2012 Filipino romantic drama film directed by Nuel Naval and starring Anne Curtis, Derek Ramsay and Andi Eigenmann.

[5][9] Since the role was created based on KC Concepcion's age, the script had to be changed and the story had to be made to suit Andi Eigenmann.

A Secret Affair, Official Trailer, Andi Eigenmann and #ASecretAffair were included on Twitter's list of trending topics.

The film received positive feedback including the impression that Anne Curtis will once again win the FAMAS Best Actress Award.
