Janet Jackson has shot down former brother-in-law Young DeBarge's recent claim that she had a secret daughter with husband James DeBarge during or around the time of their superbrief 1984 marriage. "I do not have a child, and all allegations saying so are false," Jackson said in a statement to Access Hollywood. Of course, any kid allegedly born some 20 years ago technically isn't a child at this point, so the singer has her bases covered.
