Jensen Ackles and Danneel Harris Welcome a ‘Super’ Baby

It's a bird. It's a plane. It's … a "Super" baby.

Jensen Ackles and his wife, Danneel Harris, have become first-time parents, welcoming a daughter ― Justice Jay Ackles ― on May 30.

The little one was born "happy and healthy," the "One Tree Hill" alumna, 34, wrote on Twitter Thursday night.

Justice already has a nickname ― JJ ― and if you think her full name sounds superhero-inspired, you're right.

"That is what I intended," the new mom tweeted.

Ackles, best known for his role as Dean Winchester on "Supernatural" (though many of you may still remember him as Eric Brady on "Days of Our Lives"), met Harris in 2007 when they co-starred in the romantic comedy "Ten Inch Hero." They tied the knot in the 35-year-old actor's native Texas in 2010.

"Supernatural" returns to The CW for a ninth season this fall. Harris appeared in TV Land's "Retired at 35" for two seasons before it was canceled in December and most recently she has been doing episodic work, including a two-episode guest spot in "How to Live with Your Parents (For the Rest of Your Life)."
