Congrats are in order for former Bachelorette star Kaitlyn Bristowe and her new fiancé, Jason Tartick!

ET has exclusively learned that Tartick, 32, proposed to Bristowe, 35, in Nashville, Tennessee, Monday afternoon, and now we're sharing all the details and adorable first-look photos from their engagement.

"Jason's like, 'Kaitlyn, we're not doing a podcast.' And I'm like, 'You forgot to hit record, didn't you!'" Bristowe recalled, laughing.

The two then changed into more formal wear, for a gorgeous photo of Tartick kissing Bristowe on the cheek and celebrating with a glass of champagne.

Tartick told ET that the oval-shaped ring is from Paris Jewellers, a small Canadian business right outside the town where Bristowe was born.

Tartick told ET that concerns over bringing the ring through customs resulted in a "quick adjustment" to his plans. .

(Bristowe and Booth announced they ended their engagement in November 2018, three years after he proposed to her during season 11 of The Bachelorette.) .

"I zoomed in on [Lauren Bushnell's] ring and I was like, 'Look, it's the exact one I want!'" Bristowe said at the time

The pair expanded their family with another dog in December 2019, and six months later, Bristowe was convinced that Tartick was going to propose on TV

It all happened while she and Tartick were catching up with Chris Harrison on The Bachelor: The Greatest Seasons -- Ever!At one point, Tartick reached into his pocket, which had Bristowe thinking he was going to pull out a ring

Tartick revealed to ET at the time that producers had actually asked him if he'd like to propose on the show, but he turned it down, knowing Bristowe didn't want another TV proposal

While speaking with ET before the season 29 finale of Dancing With the Starslast fall, Bristowe said it was very possible that Tartick could pop the question at home afterward, if she and pro partner Artem Chigvintsev won

"Yeah, maybe," said Bristowe, who took home the mirrorball trophy that night
