Creepiest. Guy. Ever.

It's only been one day since the Number One Fan gifted Katherine Heigl with a box of Nicorette -- and he's already hunted her down to check on her progress!


Heigl's unappointed life coach has made such name for himself that even he had to sign an autograph outside of Letterman's studio!

Better get 'em in people -- the world is officially ending!
