I watched this while I was on the treadmill at the gym last night... and let me just tell you... that was a bad idea! It ain't easy choosing between laughing.. and breathing!! LOL

Jimmy Fallon challenged Emma Stone to a lip sync battle.

He set the bar high, NAILING Iggy Azalea's "Fancy" 40 seconds in... but after that, it was ALLLLL Emma!

She owned Blues Traveler's "Hook"...

But wait til you see what she closes it with at 5:40!!! Game. Set. MATCH!
