There's upstaging, and then there's Disney-brat Ryan Gosling level upstaging.

Someone's clearly been taking lessons from a sassy child because that's the vibe that Ryan Gosling was sending off in waves while being interviewed alongside 'The Nice Guys' co-star Russell Crowe on Stephen Colbert last night.

While clearly a prepared schtick, Gosling went full 'Toddlers & Tiaras' after Crowe implied that he didn't need him for the interview, trashing Colbert's table before jamming away with the house band and then joining the audience to interrupt the show.

He's just such a sensitive soul, isn't he.

We're here and will be here for sassy Ryan Gosling forever.
