Dean Winchester makes really adorable babies. Jensen Ackles' Instagram will be a success — as long as he continues posting pics of his baby girl, Justice! The Supernatural actor shared his first Instagram ever on Saturday, Aug. 8.

"Hello Instagram," Ackles, 37, captioned the father-daughter selfie. The 2-year-old looked as cute as a button in a white top.

The hunky CW star and his wife, actress Danneel Harris, welcomed their little tot in June 2013. Harris — who played Rachel Gatina on One Tree Hill — also joined Instagram over the weekend. She shared a sweet pic of Ackles (shirtless!) holding up Justice at the beach.

"In an effort 2 squash some posers, my daughter is helping me start an Instagram profile," Ackles later tweeted. "Chk it out. Hint: it's just my name."

Ackles opened up about fatherhood last year while promoting Supernatural with costar Jared Padalecki at 2014 Comic-Con. (Padalecki and his wife, Genevieve Cortese, are parents to sons Thomas, 3, and Shepherd, 18 months.)

"[It] definitely makes you think about a lot of things," he explained. "A friend of mine was like, 'It kind of changes gears a little bit for you.' I'm like, 'No no no no, you actually put it in park, get out of the car, get in a different car, make a left on a street you've never seen before.' That's what it's like. It's humbling; it's very humbling."

He added: "Working on a show for as long as we have, when we're on set, we're not overly pampered, but people do cater to us because they want to get us on set. It's amazing how insignificant you feel immediately as you're holding this thing, and how much the world that didn't revolve around you [really] does not."
