As Breaking Celebrity News first reported, Amber Portwood’s lie detector test for bad news fiancé Matt Baier was caught on Teen Mom OG cameras — and now, fans can finally get a peek into what REALLY went down!

In the preview clip for Monday’s season finale, the 27-year-old mom sits down with her troubled boyfriend, 46, and a polygraph test administrator to go over the results. (As Breaking Celebrity News previously revealed, Portwood was determined to find out if her man had been cheating as rumored.)

“Have you engaged in any sexual activity with anyone other than Amber since October 10, 2014?” the man reveals was the first question. “Matt said no, and that’s the truth.”

Baier looks unfussed as he texts through the meeting.

“Since meeting Amber, have you had any sexual communications with other women? Matt said no, and he passed,” the administrator says.

But the father of nine secret children isn’t so lucky when it comes to the third inquiry.

“Did you make any sexual advances toward redacted?” he says he asked, as the woman’s name is bleeped out. “Matt answered no, but he did not pass.”

Hot-headed Portwood becomes enraged, and lunges toward him.

“You made sexual advances! You mother****r!” she screams.

Unfortunately, fans will have to tune in to the finale to find out what happens during the fight!

As Breaking Celebrity News reported on May 12, Portwood dumped Baier following the filming of the failed test. (The Ashley’s Reality Roundup was first to report the split.)

She later called her man a “huge pathological liar” who “needs help https://Breaking Celebrity News/celebrity-news/amber-portwood-accuses-matt-baier-lying-split-teen-mom/.”

Breaking Celebrity News first reporter Baier’s history of lying soon after the couple began dating in 2014.

Though he initially told Portwood he was a father of two, Breaking Celebrity News learned that he hid seven other kids from her.

In addition, he said he never watched Teen Mom before meeting Portwood — but in reality, he hit on costar Farrah Abraham first and regularly commented on the show on Twitter.
