When a star who's known for her wild child ways reveals she's going to be a mom, the world usually shakes with fear.


Example: When Nicole "Snooki" Polizzi got pregnant, people weren't necessarily jumping for joy.


But what's even more newsworthy than the criticism is the transformation celebrities like Snooki go through once they welcome their little ones into the world. Despite all the skepticism, Snooki proved that she's totally ditched her "Jersey Shore" reputation for days and nights at home with her son, Lorenzo.


And so have many other wild child stars turned cool moms:
