"Duck Dynasty" star Sadie Robertson clarified her rumored engagement to her boyfriend Blake Coward, how she shares her Christian faith through modesty in fashion, and her future plans after "Dancing with the Stars."

"Oh my word! Ok, so everyone thinks I'm engaged. I'm not engaged," said the 17-year-old daughter of Willie and Korie Robertson, FOX411 reports. "Me and my boyfriend have been dating for like a year and two months now so we're definitely in love I guess you could, but we're not engaged."

The rumors most likely started because of the recent announcement of her older brother John Luke Robertson's engagement to her best friend Mary Kate Eacharn. The wedding is planned for June of this year.

"Actually my brother's getting married now so we're going to let him do his thing and maybe the future."

This year is the second time that Sadie Robertson walked the Sherri Hill New York Fashion Show in her "daddy-approved" line of prom dresses with Sherri Hill that aims to set the trend in modesty. When her plan to start a modest clothing line was first announced, she received widespread support and approval from parents and many of those who have longed wished for a positive role model for their young ones in the midst of today's sex-obsessed culture.

Sadie Robertson told FOX411 how the idea of setting an example in modesty originated from her Christian values.

"It's important to me because whenever I came into the fame and spotlight I've always been a Christian and I knew that I was going to carry that out no matter where I am in life. And so I really wanted it to be something that I can share my message, and modesty kind of become my thing. That was something I could speak freely about and openly about and lead by example," she said.

Just before modeling down the catwalk in Sherri Hill fashion in New York City, Sadie expressed her gratitude to God for the experience.

"So extremely blessed to be a Sherri Hill model & get to walk in New York fashion week. Praising God for all the many opportunities. All glory to God. Walking for him!" she wrote on her Instagram page.

Sadie first modeled a cocktail dress with blue beading, which she revealed to fans in a separate Instagram post along with the caption, "work it girlll." Then, she showed herself in a stunning ocean-blue ball gown with a scoop neckline and an embellished waistline. "Sherri Hill, you are amazing!" she captioned the photo.

When asked of her future plans, Sadie said, "There's a lot of things, a lot of meetings, a lot of talk. We'll just have to see. We'll leave that one up in the air." However, she did reveal that she just got her bridesmaid dress and is extremely excited about the upcoming wedding in June."
