"Her name is Justice Jay. You know what’s funny is our pediatrician was like, well let me be the first to say, now there’s a little justice in this world. Danneel really liked Justice and she picked Jay because people call me Jay. It’s kinda a nickname, like you know whenever I go to Starbucks or something I just say “J” and it’s always J-A-Y on the cup so we just decided to use that. And we call her JJ, her name’s JJ." - Jensen Ackles at Vancon 2013
