Mommy-to-be Sarah Michelle Gellar showed off her big baby bump the other day as she took her dog for a walk and took some clothes to the dry-cleaners in Sherman Oaks.

At one point she held on tight to her baby bump.
Sarah Michelle looked cool in short, cropped jeans and a blue plaid shirt.
Gellar and hubby Freddie Prinze Jr. are expecting their first baby this fall.

I wonder, is it going to be a girl or a boy?
