"Duck Dynasty" and "Dancing with the Stars" castmember Sadie Robertson shared a heartfelt tribute Friday in celebration of her mother's birthday.

Korie Robertson turned 41 on Oct. 24, and her middle daughter posted photos and touching words to describe her love and admiration for her mom on her special day.

A split screen photo posted on Instagram shows Sadie as a toddler lying on top of her mother, both of them with beaming smiles. The second photo is a recent shot of the mother and daughter hugging each other, and wearing the same radiant smiles.

"Happy birthday to the most beautiful woman in the world," the 17-year-old captioned the post. "I think God spent a little extra time on you. not only do I get to call this beauty my best friend, a spiritual leader, and an amazing example of a classy God fearing woman, but I also get the privilege of calling her my mom.

"I don't know what I would do with out [sic] your love and encouragement," Sadie continued. "Let's make this year the best year. I pray God blesses you with more blessings then [sic] ever this year. Love you."

Over 90,000 people have "liked" the post, and many have also joined in wishing Korie a happy birthday.

Korie and her husband, Willie, have four other children: Rebecca, 24, John Luke, 19, Will, 12, and Bella, 11. Rebecca was an exchange student that the Robertson's fostered and later adopted, and Will was adopted by the couple when he was five weeks old. John Luke, Sadie, and Bella are their biological children.

The Robertson clan will soon add another family member to their fold. John Luke became engaged to his girlfriend, Mary Kate McEacharn, two weeks ago. The couple has been dating since March.

Sadie currently appears on hit ABC show "Dancing with the Stars," airing Mondays at 8 p.m. ET. The season premiere of "Duck Dynasty" is Nov. 19 at 9 p.m. ET on A&E.
