The pair have been plagued by dating rumours since before the show's finale even aired, while Tamara's ex Brent Vitiello has seen been romantically linked to Ella.
"The word is [Mitch and Tamara] are together and they have been for a while… The speculation is that it's been going on for quite a while, potentially even before filming [the reunion]," Ella said last month.
However, Tamara also cleared up speculation that she and Mitch are now dating, saying they're just "really good friends".
"And I wanna set the record straight by saying that we actually only became friends months after filming had aired," she said.
Later in the no-holds-barred Q&A, Tamara slammed Brent, claiming he hasn't stopped talking about her since the show finished in March.
"I understand that Brent has gone and spoken as much rubbish as he can about me," she said.
"There are things that I can say about Brent back that you know, really contradict some of the things he's said about me, and a lot that hasn't been shown."
The season nine "villain" went on to claim Brent didn't go on MAFS for "legitimate reasons."
Prior to their dramatic breakup in the final vow renewals, bar manager Brent accused Tamara of judging people who work in the hospitality industry.
However, Tamara also dismissed these claims, despite making eyebrow raising comments about Brent's job while filming.
"I don't look down on anyone. I come from a working class family, I'm a working class girl," she said.
"When I'm frustrated, and when I'm backed into a corner, I can get quite defensive and I can be rude, and I own up to that. It's something that I'm working on."
