"Yes," LiCausi revealed, showing off her huge diamond engagement ring.
"That's nice," Harrison said with a smile.
"Thank you," she replied bluntly.
"How did this happen so quickly? The show just ended not too long ago for you," Harrison asked, referencing how filming The Bachelor's seventeenth season concluded in November and Sean Lowe had eliminated the bachelorette mid-season.
"Is this someone you already knew?" Harrison questioned.
"Yes," said LiCausi. "We needed the separation."
"Oh you had dated before [the show]?" Harrison asked, looking for clarification.
"Yes," LiCausi replied.
"Okay then, so you're back together?" Harrison probed.
"Yeah, so, I did The Bachelor and thought I could find my love here. And as soon as I got back, we rekindled things. It was in God's favor that that's how it worked out," LiCausi explained.
"And you got engaged!" Harrison reiterated. "How long ago did you get engaged?"
"No comment," LiCausi said with a laugh.
"What do you mean? Is that a secret?" questioned a clearly confused and surprised Harrison.
"I got engaged in January," LiCausi admitted.
Harrison then congratulated LiCausi and asked whether she's heard the rumors her engagement is a "hoax."
"What haven't I heard about Tierra?!" she laughed. "It's real. It's the real deal."
"This dude exists?" Harrison joked.
"He does. He's no mystery man! I've got a good man and that's all that matters," the bachelorette noted.
While it didn't end up making it on TV, The Women Tell All's taping also reportedly featured LiCausi -- an aspiring fashion designer -- telling Harrison the date for her wedding is already set and she won't be creating her own wedding dress, according to People.
In addition, LiCausi reportedly gushed about her fiance a little bit, saying he had designed an "awesome" piece by combining two different engagement rings she had picked out.
"The guy is pretty awesome too," she added. "I am so happy."
LiCausi's 29-year-old brother Tyler revealed his sister is engaged to be married last month. The announcement followed a week of speculation sparked when the bachelorette posted several photos of an apparent large engagement ring on Instagram.
