But instead of Thomas popping the question in traditional fashion, Becca actually proposed marriage to him during a romantic picnic with a ring and all.
When looking towards the future, The Bachelorette alum Michelle Young asked Becca and Thomas how they're going to handle their last names once they tie the knot during a recent episode of the "Bachelor Happy Hour" podcast.
"Oh yeah, we're going to hyphenate," Becca said, revealing that both she and Thomas will be changing their surnames.
"Yeah, we don't know the order," Thomas shared. "I Googled it a few times and typically it's maiden name first and paternal."
Becca said she's "not sure if it matters" whether they'll become Kufrin-Jacobs or Jacobs-Kufrin.
"But we will for sure hyphenate, and we'll have our kids hyphenate too," Becca noted. "I want them to be like both of us."
Thomas went on to reveal why joining their surnames together will be "special" for their future children.
"It's because since Becca lost her father and it's just her and her sister, I just don't want to see a scenario where there's not a Kufrin going around in the world," Thomas said.
"I think that's a special thing to add, especially since in our [morning pre-engagement, tarot-card] reading, we did confirm we're having a boy."
Becca cracked up laughing and Thomas continued to joke, "We're having a boy first, when that happens."
Becca told Michelle during an early May episode of their "Bachelor Happy Hour" podcast that she and Thomas had talked about getting engaged and Thomas knows he'll need her mother's permission before proposing.
Becca also teased at the time, "He knows what I want. I know what he wants, too. So who knows! I'm not all about the traditions, so we'll see."
Becca said Thomas is "very well aware" of the fact she's already had "two very public engagements" and would like a more personal or intimate one the next time around -- nothing "extravagant" and no "big scene."
Becca had her heart broken by Arie Luyendyk Jr. on The Bachelor's 22nd season in 2018, when he decided to end their engagement because he was still in love with his runner-up, Lauren Burnham, who is now his wife and the mother of his three children.
Becca also had her very public breakup with Garrett Yrigoyen, her The Bachelorette 14 winner, in 2020.
Thomas -- who previously noted how Becca wants an elongated cushion-cut diamond ring and he could see himself proposing by the end of 2022 -- recently suggested he may have already purchased a ring for Becca.
Thomas teased on an April episode of the "Click Bait with Bachelor Nation" podcast, "Am I aware if I have one in a safety lockbox in my bedroom? I don't know, time will tell. We'll have to find that one out later on this year."
He also confirmed of the potential marriage proposal, "I don't have a full plan yet, but I know it's going to be small and intimate. There will be a camera. I'll have a photographer, but the last thing that I want for Becca is to have another grand spectacle."
Becca and Thomas plan to live in New York City for a few months this year and then settle down in San Diego, CA, long-term.
Thomas told Hollywood Life in November 2021 that he was pretty sold on marrying Becca because they have "the most healthy, normal relationship"
During an October episode of the "Talking It Out with Bachelor Nation" podcast, Thomas gushed of Becca, "I don't want to spend my life with anybody else... I wouldn't want to wake up next to anybody else."
On Bachelor in Paradise's seventh-season finale, Becca was shown breaking up with Thomas and crushing his heart before overnight Fantasy Suite dates because, despite having "an incredible start" to a relationship, Becca didn't want to leave The Bachelor franchise for the third time with a man unless she knew everything about him, including how he'd face adversity and real-life challenges.
However, the finale concluded with an update on Becca and Thomas' relationship, revealing how they had reunited after filming ended and were dating, "happy and in love."
Becca said she met up with Thomas in San Diego and they picked up right where they had left off, and Thomas told Hollywood Life that he had no hesitation or reservations about giving Becca another chance.
Becca also boasted about how Thomas is different from her past relationships because he's so passionate about a life with her and was prepared to fight "tooth and nail" to save their romance.
"He is so supportive and he's just funny and quirky in the cutest ways. Everything about him, I just felt safe with, unlike anything I had in the past. I was just like, 'This guy is my guy,'" Becca gushed.
Becca even told her mother last year, not long after Paradise ended, that she wanted to marry Thomas.
Despite having been engaged twice before, Becca admitted, "It's the first time I've ever actually said that out loud."
Since the pair began dating in the real world, Becca has defended Thomas and stood up for their relationship on more than one occasion considering he had been portrayed as a villain on Katie Thurston's season of The Bachelorette.
