Jensen and Danneel Harris Ackles Welcome Twins

It’s double the love for Jensen Ackles and Danneel Harris Ackles!

The Supernatural star announced the news on Instagram Saturday after his son and daughter were born on Friday, Dec. 2.

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

Zeppelin and Arrow join the couple’s 3-year-old daughter, new big sister Justice Jay, A.K.A. “JJ.”

A rep for the actors, who tied the knot in Dallas in May 2010, confirmed they were expecting a son and daughter exclusively to PEOPLE in August.

“Doublemint here we come!” Harris Ackles, 37, captioned an Instagram shot of five pairs of boots, each corresponding to a member of their family.

Ackles, 38, and his now-wife began dating in 2006 shortly before the release of their film Ten Inch Hero, becoming engaged three years later.

The twosome each starred on their own CW television series: One Tree Hill for Harris Ackles, and Supernatural for Ackles, on which he still stars as one half of the Winchester brothers alongside costar Jared Padalecki.

The newest additions to the Ackles family are in for one fun dad. In 2015, the actor took to Twitter to share his reasoning behind joining Instagram shortly after posting a sweet photo of himself and then-2-year-old JJ.

“In an effort 2 squash some posers, my daughter is helping me start an Instagram profile,” he wrote. “Chk it out. Hint: it’s just my name.”
