"I think it's only natural to have it on TV seeing as how our relationship started. This will be a cool opportunity to share the most special day of our lives with all the people who have been invested in us along the way," Lowe, 29, tells People, adding, "Time has just flown by – I think January is going to sneak up on us pretty quickly!"
As for the bride-to-be, she's still looking for the perfect wedding dress.
"I haven't found my dress yet," Giudici, 27, admits. "I know I want it to be form-fitting ... Not too princessy."
Other details they revealed about their special day include the decision to personalize their wedding vows, that Giudici will have a whopping 12 bridesmaids, that their honeymoon destination will be "someplace tropical" and that their reception will be "a big party."
"It's about family and friends celebrating our marriage. And that's really my only input. I'm letting Catherine make most of the decisions," Lowe says.
And Giudici already knows the one thing she doesn't want at their highly anticipated wedding.
