Is This Mei Mei's Dimple?

Papa and Mama's been wondering whether Geraldine managed to inherit Papa's dimples, just like Gwendolyn. However, since birth, there was no sign of any dimples at all, even though it's rather obvious that Geraldine will have long eye-lashes...but today, when Mama was taking picture for Geraldine, she discovered something on her left cheek! See...is this a dimple?

Can this possibly be a dimple? What do you think?
