Here it is. The moment we've all been waiting for. RDJ's journey into the THIRSTIEST social media network begins with the ultimate thirst trap.
And quickly devolves into posting pics his friends would probably prefer that he didn't.
But most important is this quick video of two meatballs meatballin, and RDJ being introduced in a manner truly befitting Tony Stark.
Spectacular RDJ. You keep doing you (on Instagram).
Now we're just waiting for the shirtless bathroom mirror selfie.
