And of course, we all know that prom night is really about pictures for the parents! Korie got a little sentimental while reflecting on her daughter's big night.

"Feels like yesterday that these two were building forts in the yard," the 42-year-old wrote on intagram. "I love every single thing about you! You were drop dead gorgeous last night, and your sweet spirit is even more beautiful than what we see on the outside. Your inner beauty shines through."

But where was Blake, Sadie's boyfriend of two years, on her big night? Sadly, a source tells ET that the couple broke up a few weeks before the big dance. (Young love!)

The split didn’t actually effect Sadie’s prom plans, however. The Louisiana native told ET last month that she always planned to attend prom with her cousin due to her ex's baseball schedule.

"We've been long distance our whole relationship -- for two years -- which is hard," Sadie said of her relationship at the time. "We're always like, 'Oh, I can't wait until we're finally just married.' That's just fun to talk about, but nothing serious."
