The curvy Modern Family star busted out of her own outfit just 20 minutes before taking to the stage with her cast-mates to accept the award for Outstanding Comedy.
"Yes!!!! This happend 20 min before we won!!!! Jajajajja. I luv my life!!!!" the Colombian star tweeted along with a photo of her bum cheeks peeking out from behind a broken zipper.
The assistant must have done a good job, because the dress held out for the rest of the night and even survived a booty-shaking celebratory dance at a post-Emmys party. Check out Sofia's awesome moves in the clip above!
