How sweet is this celebrity couple? Despite the fact that neither John Krasinski nor Emily Blunt have any hesitation when it comes to professing their love for each other in an interview, they manage to fly pretty low under the radar. John says that even his proposal was "very casual." Their smashing success as a couple could very well be attributed to how humble and low-key each actor is as an individual. Despite huge film and television success, John and Emily stay out of tabloids.
