Hey Shay, Snooki called and she wants her signature face back!

For those of you who don't know, Snooki of Jersey Shore fame invented the "duck face," or, in non-guidette terms, the "kissy face." So, it's only right that we throw the two stars in the ring together.

Shay showed off her best smooch face on Twitter yesterday (January 17), tweeting, "Just working our mirror faces." Snooks, on the other hand, flaunts her pout in almost all of her selfies.

Before you start puckering up, take a look at these ladies’ facial expressions and let's set the record straight for the queen of the duck face once and for all!
