E! got a little brighter as Hilary Duff brought her preggers glow to Chelsea Lately.

The mom-to-be, who recently revealed that she's having a baby boy, talked to Chelsea Handler about something they have in common: writing books.

Duff just released her second novel, Devoted, and is anticipating whether or not it will make the New York Times Bestseller list like her previous book, so she can be joined once again with other great authors like Handler and of course, Snooki.

But the surprising info she shared was that she didn't go to school past the third grade!

We're guessing some homeschooling was involved, but it explains why her hubby calls her a "third-grade dropout." So sweet.

Speaking of her hubby, the newlyweds faced some crazy disasters on their wedding day (note: stay away from bagels).
