Oops, sorry Kimye: Kirsten Dunst doesn't know who Saint West is

Please forgive Kirsten Dunst for living in an alternative Kardashian-free universe (oh, just imagine).

The 33-year-old somehow missed the news that Kim Kardashian and Kanye West had a baby boy named Saint West, despite the newborn becoming the butt of internet jokes last week.

Kirsten's not-so-saintly moment came during a game of "Catchphrase" on The Tonight Show with host Jimmy Fallon, Will Smith and The Roots MC Tariq. Watch her classic reaction when she drew the "Saint West" card above!

It's a shame because Kirsten Kardashian really has a ring to it. But K-Dunst obviously wastes no time keeping up with the Kardashians, scoring a Golden Globe nomination for her role in FX series Fargo on Thursday.
