Ryan Reynolds and Blake Lively have finally revealed the first snap of baby girl James… and it’s super cute.

The actor may have only joined Instagram earlier this week, but he’s already putting the image-sharing website to good use by debuting this adorbs pic of himself and his daughter…

The photo shows James holding onto Reynolds'thumb, with the star giving the image a typically quirky caption, which read: “Thumb wrestling isn't always fair. Curiously, my hand is the small one."

Lively then took to her own Instagram page to repost the pic, writing alongside it: “…and with that, my husband @vancityreynolds joins Insta.”

Ryan and the former' Gossip Girl 'actress welcomed baby James in December, with Lively revealing during an interview last month that she “looks like her daddy”.

The 27-year old blonde also went on to explain why they picked a boys’ name for their daughter, stating: “It's a family name and I liked having a boy's name, so I thought I'd pass it on."

We can’t handle the cuteness!
