The 28-year-old Big Bang Theory actress decided to forgo the workouts and crash diets that most stars do before a big awards show and instead feasted on a hamburger and french fries from McDonald's (seriously, there's proof!).
The blond beauty revealed her fast food indulgence by posting a pre-Emmys photo on Instagram of her stuffing her face with the tasty treats.
"Emmys. Here I come," Cuoco-Sweeting wrote along with the pic of her eating the hamburger in her gorgeous red Monique Lhuillier gown.
Cuoco-Sweeting shared another pre-awards show Instagram pic of a friend zipping her into the dress and, during the show, a photo with her Big Bang Theory co-star Jim Parsons.
One thing's for sure: That burger and fries sure didn't show on Kaley's hot body while she walked the red carpet!
