Oh, you’ll never guess this one.

Today’s celebrity cleavage belongs to a 32-year-old actress and comedian who got her start in the NY Improv scene, before getting her big break (HINT!) as a nerdy waitress studying microbiology. Other TV appearances have included ‘True Blood,’ ‘Best Week Ever,’ and ‘The Office.’

The 5′ tall Marlboro, NJ native currently resides in Los Angeles.

Any guesses?
