"Duck Dynasty" star Sadie Robertson has opened up about her relationship with her boyfriend, Blake Coward, revealing that she believes he's "the one" God intended for her to marry.

During a recent appearance on Entertainment Tonight, the 18-year-old model and author was asked about a recent photo she shared with her 2.5 million Instagram followers, in which she is shown standing beside Coward, covering both of their faces with a bridal bouquet. The photo, which had fans speculating about a possible upcoming engagement, included the caption, "Uh oh, look what I caught."

Speaking to ET, Sadie explained that she posted the photo "so innocently."

"And then I get home and my mom is like, 'Oh my gosh! Sadie, I cannot believe you posted that. Are you about to get married? Why would you post that?'" she told the news outlet. "I was like, 'I caught the bouquet! Of course I'm gonna post it!"

The Live Original author added that while she's confident Coward is "the one" for her, they have no plans to get engaged until after high school.

"It's kinda fun to play with my Instagram followers because, I'm not kidding you, I can post a picture of, like, a lemonade or something, and they'll be like, 'Are you and Blake getting married?' It is anything! it could be the most random thing and that's all my comments," she says. "So I'm like, I might as well make them really start talking'! It was really funny, we were just laughing' at all the comments. But no, I'm actually still in high school so we are not about to get married."

She added, "We've been long-distance our whole relationship, for two years, which is hard. So we're always like, 'Oh, I can't wait until we're finally just married and we get to be in the same place.' So that's just fun to talk about, but nothing serious."

While marriage may be far in the future for the "Dancing with the Stars" alum, she's already excited about the possibility of having children -- and someday, following in the footsteps of her parents, Willie and Korie Robertson, in adopting.

"I can't wait to adopt," Sadie said. "I try to adopt when I go on all my mission trips. I'm like, 'Mom, please let me bring them home!' She's like, 'You're in high school, Sadie. Wait til you're married.' ... I'm gonna have too many -- I'm gonna have so many kids."

Many fans are speculating that a possible engagement for Sadie may be just around the corner, however, as her older brother, John Luke, tied the knot in 2015, and her older sister, Rebecca, recently became engaged.

In an earlier Instagram post, Sadie, who is currently busy busy promoting her new fashion line for Wild Blue and walking in the Sherri Hill New York Fashion Week show, revealed why she loves her boyfriend of over one year.

"Thanksgiving is rolling around the corner & I have many things to be thankful for. 8 days from now makes 2 years with this incredibly handsome man. He's looks are pretty great, but that's not why I love him. I love him because he loves God way more than he loves me."

The reality star went on to run down a list of the young man's admirable qualities, including the fact that Blake makes her feel "special, loved and respected."

But what Sadie admires the most is how committed Blake is to his Christian faith, and this is what she is most truly thankful for: "Most importantly I can see Jesus through the way Blake lives his life...The way we have grown through the Lord is what I am truly thankful for. I love you & I'm very thankful for you Blake. 11.9.15," she wrote.
