Sadie Robertson, the teenage darling of "Duck Dynasty," has just turned 18 this June, and her mother Korie has just given her the sweetest birthday greeting.

"Today is a special day," the proud and doting mother wrote on her Instagram account (@bosshogswife). "This funny, smart, compassionate, strong, kind, shining light of a girl is 18!! I'm trying to cope. I adore being her mom, forever and always! 17 was a great year, 18 is going to be even better for you @legitsadierob Continue to walk with God and He will direct your path!"

Korie shared that post with a photo collage filled with adorable old pictures of Sadie.

Meanwhile, Sadie's best friend Mary Kate McEacharn, who is also her elder brother John Luke's soon-to-be bride, also gave Sadie a loving birthday greeting as she shared a recent photo of them sharing hugs by the beach.

"Wishing a happy happy birthday to this sweet friend of mine! Such an absolute joy to be around...always laughing and joking, and full of kindness and generosity," she wrote on her Instagram account (@missmarymcmcmc). "Thanks for the constant encouragement and for keeping me young! I can't think of anything more special than having a best friend become your sister.... I love you Sadie Mae."

Right after her birthday, Sadie had a fun time doing sports and Bible study with her family and friends at Camp Ch-Yo-Ca in Northern Louisiana.

The Robertson family is a huge fan of the camp, and have spent several summers volunteering their services to help the camp achieve its goal of bringing people closer to God.

"Camp Ch-Yo-Ca is the place for young people to grow closer to God and each other and exists because of the generosity of others," Sadie's aunt Missy wrote about the place.
