Even more special and rare are the unique names they picked for their babies: Zeppelin Bram and Arrow Rhodes.
Ackles posted on Instagram a photo of Dr. Seuss' Thing 1 and Thing with a caption that reads, "Danneel, JJ and I are excited to announce the birth of our twins Zeppelin Bram and Arrow Rhodes. They were born early yesterday morning. Everyone is doing great!"
The couple also share a daughter named Justice Jay who was born in 2013.
Congrats to the adorable family and their beautiful bundles of joy!
