Katie was reportedly a decisive Bachelorette who meant business and so production ended on Saturday, April 24 earlier than producers had planned.
"Katie was in control and made sure the men she wanted were there and the men she wasn't interested in, she sent packing," the source told the magazine.
Katie's entire season taped at the Hyatt Regency Tamaya in Santa Ana Pueblo, New Mexico, where cast and crew were required to quarantine and follow safety measures amid the ongoing coronavirus pandemic, according to Reality Steve spoiler blogger Steve Carbone.
"Tayshia and Kaitlyn can relate to Katie's journey in a lot of different ways, which you'll see play out, so it was nice to have them there to help out with whatever situation came up," the source told Us.
"Tayshia had fun and loved doing it. She and Kaitlyn made a great team."
Chris came under fire during Matt James' The Bachelor season after he defended Season 25 contestant Rachael Kirkconnell's racially-ignorant and racially-insensitive actions in the last several years during a controversial interview he had with Extra'sRachel Lindsay, who starred as the first Black Bachelorette.
Kaitlyn, who starred on The Bachelorette's eleventh season, and Tayshia, who just starred on the series' sixteenth edition last year, "were brought in at the last minute" to guide Katie through her journey to find The One, an insider told the magazine.
"They act professional, they're on time and are helping the franchise as much as they can in this funky situation," the insider revealed, although there was reportedly a learning curve and the crew missed Chris on the set.
Unlike the seasoned Chris Harrison -- who hosted the franchise ever since The Bachelor premiered nearly 20 years ago -- Kaitlyn and Tayshia reportedly had "to do a lot of retakes" during filming.
"It's a lot of memorizing lines," the insider continued. "They didn't have years of experience before hopping on. Scenes that could be done in one take with Chris can now take, like, two hours."
Tayshia teased during a recent appearance on the Going to Bed with Garcelle podcast that the world will see something "fresh and new" with Katie's season.
