Another day, another Matt Baier cheating scandal update!

Teen Mom OG star, Amber Portwood put her man to the test — a lie detector test, that is.

The polygraph test results were all caught on camera, which means Teen Mom fans are in for a dramatic Monday night season finale.

In a sneak peek, the administrator of the test asks Matt, “Have you had any sexual communications with other women?”

Amber then yells, “I’m about to freak out, I’m about to freak out!”

However, Amber said she's actually pleased with many of the results.

“I wasn't against it because I guess I kind of felt like I wanted to know,” she told Us Weekly. “I was happy with some of the results…it clarified some things. I think people will actually be shocked with some of the results. Some of them actually pleasantly surprised me and made me feel amazing and I think it [will make] a lot of people look really stupid that [have] always been talking s–t.”

This isn't the only time the couple has been in the news recently.

Rumors of domestic abuse surfaced after the star posted a questionable photo to her Instagram account.

“Battle wounds,” the 27-year-old wrote in the June 13 caption, adding the hashtag “#DontSlideDownAfterYouPunch.”

Despite their tumultuous relationship, the couple has decided to give their relationship another shot. Earlier this month, it was announced that the pair are headed to Marriage Boot Camp Reality Stars: Family Edition.

“They’ve been in talks with production for a while,” a source revealed.

Here's to hoping the on-again, off-again couple can work things out this time!

Tune in to the season finale of Teen Mom OG airing Monday, June 26 at 10 p.m. EST on MTV.
