“Love!!! #bigsister #somuchbabygearinhere,” she captioned the image of daughter Justice “JJ” Jay, 3, and their 3-month-old twins – son Zeppelin Bram and daughter Arrow Rhodes.
The Supernatural star, 39, posted a photo of the twins earlier this month.
In January, the proud papa introduced his newborns via social media.
The Smallville alum and the One Tree Hill actress, 37, welcomed the twins on Dec. 2, 2016.
“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! #twinning,” Ackles announced at the time.
