According to Us Weekly, the reality pair - who initially revealed their engagement in April - have confirmed that they will marry on November 6.
"One thing led to another, and it's all been great! We both knew, right away," said Durr.
"We were actually the first Bachelor reunion couple to get engaged but Jesse [Csinscak] beat us to the altar!"
She revealed to the magazine that they will marry in St Augustine, FL at a ceremony attended by over 600 guests, and are hoping to settle down together in the state following a long-distance romance, although they are still finalising their post-marriage plans.
Durr appeared on the sixth season of The Bachelor fronted by Lorenzo Borghese, while Presser was a contestant on Jillian Harris's season of The Bachelorette. They met through a Bachelor Facebook page and later in person at a Bachelor/Bachelorette reunion.
