And babies make five!

Supernatural star Jensen Ackles and wife Danneel Harris Ackles are now the proud parents of three kids. The 37-year-old former One Tree Hill actress welcomed twins, Jensen revealed on Instagram on Saturday.

"Danneel, JJ and I are excited to announce the birth of our twins Zeppelin Bram and Arrow Rhodes," he wrote alongside a photo of Dr. Seuss' characters Thing 1 and Thing 2. "They were born early yesterday morning. Everyone is doing great! #twinning."

The pair first announced that they were expecting twins — a boy and a girl — in August with an adorable photo of the family's cowboy boots.

The two married in 2010 and welcomed daughter Justice Jay, who they've nicknamed JJ, in 2013.

Now, with two extra additions, they have their own little superhero crew. Congratulations to the family!
