Sorry guys, Sadie Robertson is off the market. The 21-year-old reality star is engaged to Chrisitan Huff.

The "Duck Dynasty" alum shared the news with her 3.2 million Instagram followers Sunday night. The post shows the couple canoodling next to each other on a wicker loveseat accompanied by a bottle of champagne. Huff guides Robertson to her feet before getting down on one knee and proposing.

"I screamed YES," Robertson captioned the video. "So many words and so many more pictures to come, but for now just know my friends I’m the happiest human in the world on June 9th, 2019 today and for the rest of my life."

"I GET TO MARRY THIS MAN. God is faithful and so so good," she added.

Korie Robertson, Sadie's mother, and fellow "Duck Dynasty" alum, shared the excitement on her Instagram as well.

"Sadie’s getting married!!!!! To the most amazing man, and we are beaming!!! Today was an absolute dream," she captioned the four photos. "I love every second of being @legitsadierob mom and can’t wait for @christian_huff to join the fam!"

The engagement wasn't the only thing the couple celebrated on Sunday. Robertson's boyfriend, now fiancé, also celebrated his 19th birthday. According to Us Weekly, Sadie shared the news earlier in the day on her InstaStory.

“It’s my favorite humans birthday," the star told fans. "...get ready for a lot of pics and a lot of words shared throughout the day."
