The Duck Dynasty kids are all grown up!

Sadie Robertson – the 18-year-old daughter of former reality stars Willie and Korie Robertson – attended her senior prom Friday alongside cousin Cole Robertson, 18.

Sadie captioned a Saturday Instagram photo of the two together, all dressed up, “making mems with the fam is the best, because we can laugh about them forever. thank you for always being there cuz! couldn’t do life without you!”

Sadie’s mom was feeling nostalgic herself. Along with a Saturday photo of Cole and Sadie heading to the prom, Korie wrote, “Feels like yesterday that these two were building forts in the yard. Last night was their senior prom.”

She continued, of Cole, “What an awesome man of God you have become. So proud of you, and [Sadie] 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.”

Still, the occasion wasn’t all that serious. On his own Instagram, Cole posted a photo of him and Sadie looking silly.

He wrote, “I mean who wouldn’t have fun this date? Had a blast with you cuz we should do this more often
