TS Entertainment recently�confirmed, that SECRET will have a comeback on April 30 with a mini album., 'Letter from SECRET'. To gather excitement for the impending release, they have just released the first image teaser for leader Hyosung.

In the new teaser photo, Hyosung is dressed as cheerful ing�nue�reminiscent�of the days of Marilyn Monroe. She is giving off a refreshing feeling with her white headband and dress, while adding some�pizazz with her colorful sneakers. It looks like rather than the sleek and sexy image of their recent promotions, the ladies are going back to their a more bubbly concept.

The mini album will contain 5 songs, and the title song, "YooHoo", will be produced by�Kang Ji Won and�Kim Ki Bum, the same duo who created their hit songs "Magic", "Madonna", "Shy Boy", "Starlight Moonlight", "Love is Move", and "Poison".
