Watch out for those gowns.

Naomi Watts tripped over Emma Stone’s gown while on stage with her “Birdman” co-stars accepting the award for Outstanding Performance by a Cast in a Motion Picture. The stars were making quick speeches at the microphone and when Watts walked up to say something, she took a tumble over the sheer train of Stone’s Dior Couture dress.

“Oh my god, wow!” Watts said, as a wide-eyed Stone apologized for the mishap behind her.

Don’t worry, Naomi, It happens to the best of ‘em (just ask Jennifer Lawrence).
