Katherine Heigl and Ashton Kutcher play the ultimate mismatched couple in the upcoming action comedy, Killers. While Heigl plays the ever-so-trusting Jennifer Kornfeldt, Kutcher stars as Spencer Aimes, the man who punks Kornfeldt by neglecting to tell her he's really a CIA agent. To make matters worse, a close friend of theirs (Rob Riggle) is hired to kill the pair not long after their nuptials. Guess someone's not a fan of Heigl's romantic comedies.
