Ashley Graham just shared a glimpse of her and Justin Ervin’s anniversary adventures!

On August 14, the model and starde Side Hustlers, 36, and her filmmaker husband, 38, celebrated 14 years of marriage. To celebrate, they took a break from the big city and enjoyed a relaxing and romantic moment in nature.

Graham shared a glimpse of the anniversary getaway on Instagram on Tuesday, August 18, with a curated photo package she captioned, “Celebrating  our 14th.”

In the first photo in the collection, the couple — who share three sons, Isaac, 4, and twins Roman and Malachi, 2 — posed for a sweet, blurry selfie, with Ervin wrapping his arm around Graham and planting a kiss on her forehead as she smiled.

While she didn’t reveal exactly where they stayed, the star did include several photos of the spot where they stayed for their anniversary: ​​a secluded spot, with wood paneling and floor-to-ceiling windows. To enjoy the forest around them, the couple did some exploring, hiking, and even went skinny dipping.

In one of the photos, Graham poses nude in a river, smiling, and later confirmed that it was taken while she and Ervin were enjoying a spontaneous nude walk in the water.

The anniversary comes just months after Ervin celebrated another milestone, his 38th birthday, which Graham celebrated with a heartfelt tribute on Instagram. He posted two photos — one of the longtime loves looking into the camera and another of them sharing a kiss — and wrote, “Another year of loving you.”

The couple met at a church event in 2009 and got engaged the following summer. In an interview with PEOPLE at the time, Graham, then 22, said, “It’s amazing.”

“We come from different backgrounds,” he continued, “but we have the same views on religion and family.”

They married shortly afterward, on Aug. 14, 2010 (Ervin didn’t want to wait long), in a ceremony that focused on tradition, according to Graham.

“I love tradition. Our vows were traditional, my dress was a little bit traditional, but everything else was very modern,” she toldHarper’s Bazaarthen.

The nuptials, she continued, were “a celebration of each other. It was a traditional thing. It was a celebration of what the rest of our lives would be like and the most important people in our lives.”
