Carrie Prejean must have a really, really bad memory -- because TMZ uncovered a brand new set of topless photos "biblically correct" Miss California took before she applied for the crown.
These pics were taken just last year -- meaning Carrie was the ripe ol' LEGAL age of 20.
This time, Carrie dropped her top for a professional photo shoot ... another partially nude gig that she forgot to tell the Miss California officials about.
Donald Trump will decide today whether or not he'll give Carrie the heave ho.
UPDATE: At today's presser, Trump let Carrie keep her crown.
