Graf told People she quietly took a pregnancy test while watching The Bachelorette finale with Nickson in August and initially forgot to check the results.
"I just went and laid back in bed with him, pregnancy test in my hoodie pocket. The show distracted me so I had forgotten it was in there until after it ended. I pulled the stick out and immediately gasped at the result!" the star recalled.
"Cody looked at me scared and confused at the look on my face when I handed him the stick! He immediately burst out into laughter and I burst into tears! It was the best surprise!" she said.
Graf and Nickson, who is already dad to 6-year-old daughter Paisley, met during Big Brother Season 19 and got engaged in February. The couple won The Amazing Race Season 30 the same month.
