Such a tease.

Ryan Reynolds only just joined Instagram, but it’s already paying dividends.

The actor, 38, posted a picture of his and 27-year-old lifestyle-entrepreneur-actress-type Blake Lively ‘s brand-new baby girl, James (James? I dunno).

Admittedly, it’s a total Rocket Zot (I… I don’t know) style tease, showing just the baby’s teeny little hand.

Cuteness.

“Thumb wrestling isn’t always fair. Curiously, my hand is the small one,” Reynolds captioned the pic. Funny and handsome? It’s just too much!

Lively regrammed the picture, “…and with that, my husband @vancityreynolds joins Insta.”

The proud parents welcomed sweet baby James in December.

The funny couple, pre-baby.

Lively, currently appearing in The Age of Adaline, reckons she’s going to raise a kid with a well-developed palate.

“Oh, I rub truffles on my nipples every time [I nurse her],” she told a Canadian newspaper.

“You can’t be around me and not be exposed to all different cuisines.”

What, she’s funny now, too? Too much!

Check out Blake’s wardrobe. Because… well, why not?
