The Bravo star opened up about the idea behind the football-inspired gift in a recent interview with E! News, sharing that the special two-month-long project was completely worth it in the end.
"This gift I really loved," she said. "So it's a book, the company's called Best of Legacy and what they do is they take Kroy's entire football career — you could pick just the NFL but I did high school, college and through the NFL — and there's like 300 articles on him, pictures and there's video of some of his biggest plays."
"He got a touchdown," she said of the unique present.
"It's this huge book of his entire football career, which is so awesome from start to finish. I spent like two and a half months with the company working on it and I was so excited." the Don't Be Tardy star, 42, revealed of the heartwarming gift. "I could not wait to give it to him."
The former Atlanta Falcons player told the outlet that the gift was "so incredible."
"We're both so hard to shop for because we both have everything that we want, so for her to find that and spend the time, it was very thoughtful and such a cool gift. And a lot of those articles I forgot about, they happened in high school and my early career," he said.
While putting the project together, Zolciak-Biermann said she learned even more about her husband.
"There's video in there of him in high school or college. It's really cool," she explained.
"He'll have that forever, the kids will have that and be able to look back," she added.
Zolciak-Biermann and Kroy celebrated the special occasion with a low-key day followed by a glam dinner date.
