However it has been a bumpy journey for Girardi, as she has bickered in the house with many of the other bachelorettes -- who have been vocal in discussing their dislike with her to Pavelka.
Harrison said those "little jabs" Girardi throws are "not a big deal" by themselves.
"But add them up, and it's a big deal, especially in this pressure cooker of The Bachelor," he told Us.
Pavelka has also previously expressed his displeasure with Girardi's desire to be the last woman he talks to before a Rose Ceremony, but Harrison said she has good intentions.
"There are those little moments where she says, 'I want the last conversation.' Jake even realized, 'Back up a little bit. Don't go out of your way to throw it in the girl's faces.' But she is not there to make friends," explained Harrison to Us.
"She loves Jake and that's it."
In addition, Girardi's former mother-in-law recently claimed the bachelorette wiped out her ex-husband's life savings to pay for breast implants while he was deployed in Iraq. The ex-husband, Josh Riley, also accused Girardi of cheating on him while he was deployed and called marrying her a "mistake."
Still, Harrison said Girardi is "very similar" to Pavelka and feels she is different when she's around him.
"I think people read Vienna as this antagonist. She is not the antagonist, and you have to see it when she is with Jake," he told Us.
