The former “Duck Dynasty” star posted a photo of herself and Huff, 22, at an undisclosed beach that had a wooden swing set at the edge of the sand before the ocean.
Robertson, 23, wore a printed one-piece swimsuit while her husband sported blue swim trunks.
“Just two kids on Gods play ground,” the “Live: Remain Alive” author captioned the photo as they goofed around on the swings.
Robertson and Huff got married in November and have been more open about their relationship since then.
“When I met Christian, his love is so sweet and so kind and so grace-filled that the times that I would be hard on myself, I would see the grace and the love he would extend to me and be like, wow, that’s real love, and that’s really a powerful thing,” the former reality star told Fox News in March.
She added: “And, I’ve watched myself really walk away from that self-doubt and walk into a true confidence, because just the way that he affirms me and I look at that relationship and think about that love and that’s me and Christian, that’s human. And then, I think about what is God’s perfect love? Wow, that’s overwhelming.”
Last month, Robertson gushed about Huff in a sweet tribute for his birthday.
“A year ago from today I called you my FIANCÉ for the first time and it felt so strange. Wild how one year has gone by and husband is the most natural thing to call you. You are my better half,” she wrote.
Robertson continued: “Can’t wait to see you at 82 old man, sitting beside you in a rocking chair talking about what we are reading while I drink only half my matcha and you sing ‘and another matcha bites the dust’!”
