Kirsten Dunst is 'clueless' about Kim K's son

While everyone around the world is keeping an eye on Kim Kardashian and Kanye West's newborn Saint West, Kirsten Dunst is clueless about his existence.

When the 33-year-old actress played a game of catchphrase on 'The Tonight Show,' she appeared absolutely clueless about what "Saint West" meant when the name came up, reports E! Online.

The 'Fargo' star asked host Jimmy Fallon, "What is that?" drawing a loud response from the crowd.

Saint is Kardashian and Kanye's second child. The two are also parents to daughter North West.
