Ryan Reynolds has shared the first picture of his baby daughter on Instagram – see it here!

The picture sees baby James' little hand holding onto her dad's thumb. Reynolds, who only joined Instagram this week, posted the picture with the caption, "Thumb wrestling isn't always fair. Curiously, my hand is the small one."

New mum Blake Lively also shared the picture adding to his caption, "... and with that, my husband @vancityreynolds joins Instagram."

The couple welcomed their baby girl at the end of 2014, with news breaking in January. Reynolds and Lively met on the set of 2011's Green Lantern and tied the knot in Mount Pleasant, South Carolina in 2012.
