"Duck Dynasty" star Sadie Robertson recently attended prom with her cousin, Cole Robertson, after splitting from her boyfriend of two years, Blake Coward.

The 18-year-old actress and model, whose parents are Willie and Korie Robertson, accompanied by her cousin Cole Robertson, the youngest son of Jase and Missy Robertson, at the school dance in Monroe, La.,

Sadie, who appears in the recent faith-based film "God's Not Dead 2," posted a photo of the two of them all dressed up on Instagram with the caption, "Making mems with the fam is the best, because we can laugh about them forever. thank you for always being there cuz! couldn't do life without you!"

For the special night, Sadie wore a gorgeous floor length ball gown from her line of "Live Original" prom dresses, made in collaboration with Sherri Hill, that reflect her Biblical views on modesty.

On her personal Instagram page, Korie Robertson shared a photo of the cousins, praising the two for living out their Christian faith.

"Feels like yesterday that these two were building forts in the yard. Last night was their senior prom," she captioned the photo."@littlecoleofcereal What an awesome man of God you have become. So proud of you, and @legitsadierob I love everything about you! You were drop dead gorgeous last night, and your sweet spirit is even more beautiful than what we see on the outside."

Missy Robertson also posted a photo of the night to her social media accounts along with the caption: "How do you cut out the drama surrounding prom night? Take your cousin, of course! It also ensures a pretty fun evening. Have a great night, kiddos!"

While many "Duck Dynasty" fans were convinced Sadie would be the next to walk down the aisle following brother John Luke's wedding last June, a rep for the Robertson family confirmed to Us Weekly that the couple broke up several weeks ago.

However, Sadie, who is also a "Dancing with the Stars" alum, hasn't let the breakup slow her down, making her film debut in "God's Not Dead 2."

In a recent Instagram post, she revealed that she believes the film, which stars Melissa Joan Hart and Jesse Metcalfe, will change lives.

"... Truly an amazing film. I am so honored that I got to be a part of this Gods Not Dead Movement," she wrote. "It will encourage, and inspire all people."

The movie, a sequel to the 2014 production "God's Not Dead," follows a junior high teacher, Grace, as she attempts to express her Christian faith that results in her facing a lawsuit from a civil liberties group in the process. The teacher and her defense team must prove through historical, not religious evidence -- that Jesus truly existed. 

"If [Grace] would have wavered in her faith, then it wouldn't have worked out for her," Sadie recently told Town Hall of the film. "Because she stayed true the whole time, and never doubted it, she was very successful. People wanted to root for her."

Sadie noted that in her own life, she relies on prayer to give her the courage to remain strong in difficult situations. 

"Many times," she said. "The time that you don't you always regret. Every day I pray that God will breathe through me and I seize every opportunity and I don't miss them. Whenever you see everything as an opportunity, it changes the game. When you don't look for that, you come off shy. Anyone that's really scared of doing that, the movie says it so well."
