The couple, who met on Season 9 of the reality show, discovered Hartsock was pregnant on Valentine's Day in Maui, Us Weekly reports. "I kinda knew, like, 'You know something, I think I'm pregnant," Hartsock said. "We were in Hawaii when we went for our one-year anniversary. That's when we took a test and found out!"
Hartsock and Siegfried became engaged on The Bachelorette finale in May 2013, but didn't tie the knot until January 2015.
