Jason Momoa, might just be the coolest man out there but even he can't maintain the casual vibe when meeting everyone's favorite Pretty Woman, Oscar winning actress Julia Roberts.
The Aquaman star and his mom ran into Roberts when the two actors appeared on The Late, Late Show with James Corden.

It was all professional while shooting with fellow actor Yahya Abdul-Mateen II, but behind the scenes Momoa and his mom admitted to "geeking out" over meeting Roberts.
Momoa posted the photos to his Instagram account.

And his followers totally understood the freak-out.
It looks like a great time was had by all!
Well, okay, but it still looked pretty fun.
