Narrative:

After being cleared to land; I lowered the landing gear and verified three green lights indicating the gear was down and locked. The passenger in the right seat; my mechanic also confirmed three green lights. I then selected approach flaps and upon entering short final; selected full flaps and again verified three green lights. There was no gear warning horn sounding; again indicating the gear was down and locked. On short final; I again verified three green lights; props forward and mixtures full rich for landing. On reducing power over the runway; again there was no gear warning horn; indicating the gear wads down.the landing was very normal; but upon lowering the nose; the nose gear collapsed; resulting both props striking the ground. At this point the nose gear light went out and the gear horn sounded. I do not yet know the cause of the gear collapse; but it seemed as if the drag brace suddenly failed. Alternatively; the nose gear may not have been locked in the down position; despite the green light indicator and lack of gear horn.
