While Kaitlyn is thrilled to be getting married, hopefully on New Year's Eve 2022, she said she's actually "most excited to be starting a family," Us Weeklyreported.
"I would probably do that now," Kaitlyn said of having a baby, "but Jason's more on the traditional side and says we have to get married first."
The Season 29 Dancing with the Stars champion therefore confirmed she and Jason will be on "the fast-track" to family planning after saying, "I do."
"It's been a way longer engagement than I thought. I remember we got engaged in May  and we were like, 'Okay, we'll do it in May of next year.' And now we're in June and I'm like, 'Holy crap, that happened so fast,'" Kaitlyn told Us.
"So I think we're enjoying the engagement and we'll do a little fast-track to fam."
Kaitlyn shared in early April how she thought a baby is "close" and in her near future.
When asked what's coming up for the couple, Kaitlyn told E! News at the time, "I want to keep growing my businesses. My dream vision board probably [is] host Dancing with the Stars and have babies."
And Jason confirmed the "babies" part may happen pretty soon.
"Your psychic said you were going to... [get pregnant]," Jason reminded his fiancee, to which Kaitlyn responded, "She did. She said that 'your baby is close.'"
But in the meantime, the lovebirds are planning their "over-the-top" wedding and have decided the big day will take place in Nashville, TN, where they currently live.
Kaitlyn previously joked with Us how she had been experiencing "baby fever" for about 10 years.
Kaitlyn would apparently like a big family, but she has realistic expectations.
"I have so many girlfriends who have struggled with getting pregnant that I'm truly just happy to even have one," Kaitlyn told the magazine earlier this year.
"If that's in the cards for me, what would I ideally love? Probably three but [I'm] not getting any younger. So, I don't know if that's going to happen."
Kaitlyn got the ball rolling on her wedding plans before leaving for the Dancing with the Stars 2022 winter tour in mid-January.
"I was like, 'Jason, we got to lock down a wedding planner because once I'm gone, I'm not gonna be able to do much and I'm not too picky about things,'" Kaitlyn told Entertainment Tonight of the planning process at the time.
"I'll let the wedding planner, as long as I trust them, do their thing, so hopefully that will make it easier."
Kaitlyn, who co-hosted The Bachelorette's seventeenth and eighteenth seasons with Tayshia Adams, had originally planned on a Summer 2022 wedding.
"I just know that basically as soon as we can get the ball rolling, I want it to be a Great Gatsby-like, black-tie event -- very glam, which is so opposite of what I thought I would want," Kaitlyn revealed in June 2021.
"Because four years ago, I would have been like, 'I want bohemian. I want it farm-style.' I just keep changing my mind."
Kaitlyn first met Jason while taping an episode of her "Off the Vine" podcast in October 2018, and he took her out on their first date in January 2019.
Jason -- who finished Becca Kufrin's The Bachelorette season in third place in 2018 -- moved from his place in Seattle, WA, to live with Kaitlyn in Nashville in June 2019. The couple has since adopted two dogs together.
