We were just two kids who were crazy about each other," Nikki wrote. "We didn't yet know how to grow with someone, but we knew we were in love and we knew we wanted to learn all of these things…together.
"I still have no idea if we're doing it right, but I know we both wake up everyday and choose each other. We've seen a lot, we've done a lot, we've laughed a lot, we've laughed a lot of it off, and we've continued to be each other's biggest cheerleaders, and truest support system. An amazing thing happens when you merge your life and soul with another. Your relationship becomes its own beautiful garden that continues to bloom."

"May this next chapter be filled with curiosity and even more admiration for all the incredible things we still continue to discover," Nikki said.

Happy four years married my honey."
In addition the glowing post, Nikki posted several images from their wedding day to her Instagram Story, saying she was getting "teary-eyed" looking at them.
