Olivia, who caused waves on the show when she shared an OnlyFans photo of Domenica Calarco, claimed Ella had convinced her 'husband' Mitch Eynaud to stay on the show, despite the fact he "never liked" her.
Speaking to the Where's Your Head At? podcast, Olivia and her on-screen husband Jackson Lonie claimed "you could see that every time they got on the couch, something's not right here".
"Mitch is going to kill me, I love Mitchell, I think he's one of the best men on MAFS, but he never liked Ella," Olivia claimed.
"It was never a thing for him, and she was like, 'The longer we stay on this, the more money we make'."
Ella, who is a loyal friend to Domenica, is one of the most popular influencers following this season of MAFS, racking up more than 560,000 followers on Instagram compared to Olivia's 162,000.
However Olivia claims there is a different side to the star that fans didn't see.
"She always had this weird smug smile whenever I spoke to her one-on-one, she always seemed competitive with me over whose relationship was stronger," Olivia told the podcast.
"I liked Ella, I thought we got along at the hens night and I was really surprised when she was so 'Team Dom' and started having digs at me."
Throughout the experiment, Ella and Mitch stayed together but he later dumped her after the final vows.
The pair got back together but Mitch broke up with Ella again following the reunion.
Rumours have since been swirling that Mitch and co-star Tamara Djordjevic are dating, however, she rubbished the claims and said they were just good friends.
Meanwhile, Australia is attempting to ship Ella and Tamara's on-screen husband Brent Vitiello, with the pair admitting they have kissed since the show aired.
Speaking about their relationship, the pair said they were not official.
