They named her Justice Jay Ackles, and are apparently calling her J.J.
I know Jensen goes by "J" in real life, so the middle name is pretty cute. And I saw Danneel's comment about wanting the baby's name to sound like a superhero, so ok. It's not my fave name, but it's also not my baby. :)
BUT MORE IMPORTANTLY. Let's dwell for a moment in the fact that Jensen legitimately named his daughter J2. O_O
*two thumbs up*
And now, little J.J. and little Thomas must grow up and produce more pretty babies together. (Too soon to ship it?)
