Duck Dynasty's Uncle Si is probably one of the most beloved and talked about members of the Robertson family, so granddaughter Sadie thought it would be a great idea for him to share some pearls of wisdom with her Instagram followers.

Sadie posted an adorable black and white selfie with Uncle Si on her Instagram account (@legitsadierob) and included the funniest caption.

In it, she asked Uncle Si what message he would like to give her 1.8 million Instagram followers. Uncle Si simply looked confused, according to Sadie, and asked, "Instagram?? Stop following & lead JACK!"

Sadie and her followers thought that Uncle Si was just hilarious, but she quickly added a postscript that read, "Take his advice in life but please don't take his advice on Instagram!"

The teenager injects a lot of humour in her Instagram posts, and she often includes her family members. Earlier this year, she shared a sweet photo of her with beau Blake Coward. The two were all cosied up under an umbrella; that is, until her father Willie photobombed the pair and pulled a wacky face from behind.

"What's a picture without a photobomb," quipped Sadie at the time.

In another Instagram post, Sadie shared a throwback of a beardless Willie. "Yes that is my dad," confirmed Sadie, much to the surprise of everyone who saw the photo.

She also enjoys sharing pictures of herself with Coward, but he is currently away because of college and the two are trying to make the long-distance relationship work.

She gushed about how Coward signed on to play basketball in college: "Words can not express how happy I am for you & how proud I am of how much hard work you put into for this. You definitely deserve it. Mostly I am proud of the example you set on every team you were on. You played for God & you are definitely being rewarded for that. I can't wait to continue to cheer you on & be your #1 fan."
