Katie had to put on gigantic boobs for her role as Samantha in the movie Click.
Katie: (About her most memorable moment while filming Supernatural) In the second episode, I'm at a diner and I put ketchup on my plate. I'm supposed to put a big load of ketchup on my plate. So, I'm squeezing the bottle and on about our third take...I think someone had unscrewed the top to play a joke on me because all of a sudden ketchup flies all over me and all over plate! I had just started on the show and everyone was laughing. It kind of broke the ice for me to make me feel more welcome on the set. It as kind of embarrassing, but it was fun.
Katie: (on working with the cast of Supernatural) It's been really great! They're really talented actors and such sweet boys. They really make you feel welcome and they are goofballs. It's been really fun! I've had a great time.
