Married at First Sight star Brett was allegedly already dating another man while she was filming the last several weeks of the show's thirteenth season with her husband Ryan Ignasiak.

The @MAFSfan Instagram account posted a series of images and videos Tuesday on Instagram Stories claiming Brett became involved with another man while she was still married to Ryan and filming the conclusion of the extreme experiment.

Brett allegedly began dating her new guy a few weeks before Ryan was caught having downloaded a dating app a week before "Decision Day," when the couple would have to formally decide whether to remain married or divorce.

"Ryan has been heavily criticized on social media for downloading a dating app a week before Decision Day (which is horrible, don't get me wrong). However, things are not always as they seem," read a @MAFSfan Instagram-Stories posting.

"The real tea: Brett started dating her current boyfriend the first weekend in April. This was shortly after the 1 month anniversary but prior to the couples retreat."

@MAFSfan pointed out how it seemed Brett's "behavior and attitude" changed before and after the couples retreat at a ranch. Brett was initially very upset about the demise of her marriage to Ryan and their lack of communication, and then it seemed like she no longer cared.

"[Brett] goes from a trying attitude to [an 'I don't give a f-ck'] one," the account wrote.

Ryan slowly distanced himself from Brett in the weeks that followed their wedding day, but right when Ryan determined he must not give up and should put more effort into his marriage, it appeared Brett's interest in the relationship had waned.

Earlier this season, Ryan claimed during in appearance on Married at First Sight: Unfiltered that Brett had allegedly repeatedly stayed out late into the early-morning hours during the week proceeding the season's couples retreat weekend.

"I felt really good... and then Sunday comes around and I make her breakfast, we go to the gym on Sunday, and then she didn't come home until 2:30 in the morning on Sunday! She does the same thing [two days later] on Tuesday!" Ryan claimed.

"How am I supposed to build [any type of intimacy] going into this [retreat] weekend?"

Ryan said although he "probably deserved" that kind of treatment from his wife at that point in the process, he said Brett "wasn't present that whole week leading up to" the couples retreat.

"This is when she met and started dating the new guy," the @MAFSfan account alleged.

"While it is clear that the relationship between Ryan and Brett was doomed to fail, it is interesting that Brett seriously dating someone else for nearly half the experiment never came up on the show."

@MAFSfan essentially suggested Brett was being a hypocrite confronting Ryan about downloading a dating app while she was spending time dating a new man.

"I think it's interesting that Brett acted shocked over Ryan downloading a dating app when she was already in a new relationship at that point," the account wrote.

The account proceeded to share some Instagram DMs and comments it had received, including one from a person claiming Brett is "still with the guy she was seeing" while she was filming Married at First Sight with Ryan.

"Y'all have been fooled. And Ryan was just nice enough not to throw her under the bus," the person alleged.

And another fan commented on how Married at First Sight "portrays a bunch of BS" and Brett had allegedly been hiding this supposed secret relationship.

The account teased how proof of Brett's alleged betrayal will come out soon from another source or media outlet.

When only two weeks remained until Decision Day, which is when the couples retreat commenced, Ryan said on Unfiltered his relationship with Brett would need "a Hail Mary" to survive.

Ryan explained to the cameras a spark was missing and he didn't feel an attraction to or butterflies for Brett.

Meanwhile, Brett was waiting to learn the truth from Ryan and have her husband open up about his feelings.

Brett had also noticed a sudden change in Ryan's attitude and demeanor, and his sister suggested to Brett that a woman from Ryan's past may have resurfaced and resulted in Ryan being distracted -- a claim he later denied.

Brett even suggested to her fellow Married at First Sight brides at the couples retreat how she felt devalued and disrespected by Ryan. She claimed Ryan had broken her.

During a late October episode of Married at First Sight, Brett confronted Ryan about an allegation she had heard.

"I got a text from a friend like 10 minutes ago that showed that you are on a dating app -- and matched with someone that I know," Brett told Ryan.

Brett said she couldn't believe that her husband couldn't wait just one more week until Decision Day to "jump back in" the dating pool.

Brett told the cameras that honesty is not Ryan's strongsuit, and she told her husband, "It doesn't line up with things you say about respect. So, if it's about respect, that ain't it. Respect is a big deal and you made that very clear."

Ryan replied, "I'm sorry that came up that way. I mean, I would like to show you that I didn't talk to anybody and that it's not even active."

But Brett countered, "Yeah, I don't even see how that's going to help. You obviously downloaded it for a reason."

"Well, I will get out of here," Ryan responded.

Ryan insisted on Unfiltered after the episode aired that he didn't have a single conversation with a woman and hadn't matched with anyone after downloading the app.

"It was maybe active on my phone for four minutes," Ryan said.

Unfiltered host Jamie Otis, however, pointed out, "It doesn't matter. You downloaded that while she was being vulnerable and you were being vulnerable with her."

Ryan then shared, "After the retreat, I was pretty checked out. [I checked out] prior to this moment that we had [about the dating app]."

Ryan admitted of how he had handled the situation, "I don't like escalating situations. I like being able to calmly resolve them... I should have apologized there. I absolutely wish I would have done that."

Ryan eventually moved out of his shared apartment with Brett, and it was clear their marriage had ended in the week leading up to the couples' final decision when they must determine whether they'd like to stay married or get a divorce.

Married at First Sight airs its Season 13 "Decision Day" episode on Wednesday, November 10 at 8PM ET/PT on Lifetime. The season also stars Johnny Lam and Bao Huong Hoang, Gil Cuero and Myrla Feria, Michaela Clark and Zack Freeman, and Rachel Gordillo and Jose San Miguel.
