You'll Never Guess What Kristen Stewart Said During a Game of "Word Blurt" With Jimmy Fallon

Kristen Stewart dropped by The Tonight Show on Tuesday to promote her upcoming movie, American Ultra, which hits theaters Aug. 21. During her appearance, Kristen and Jimmy had some fun playing a hilarious game of "Word Blurt." The rules were simple: Jimmy and Kristen got cards with random words on them, such as "marshmallow" and "Lenny Kravitz," and they had to shout out the first thing that popped into their heads. Watch the funny clip above, and then check out Kristen's awkward Funny or Die interview with Jesse Eisenberg.
