The final straw? In an explosive sneak peek clip for Teen Mom OG's season finale this Monday night, Amber Portwood isn't holding back!
Amber's now ex-fiance, Matt Baier, takes a lie detector test and it was all caught on camera, as RadarOnline.com exclusively revealed.
As seen in the clip, an unknown man is seen asking Matt, "Have you had any sexual communication with other women?"
And by the looks of it, Amber isn't okay with the results! "I'm about to freak out, I'm about to freak out," she said while being held back by another unknown man.
In was reported mid May by RadarOnline.com that Amber and Matt finally called it quits after he failed the test. “Amber says he didn’t pass,” a source close to Amber said. The Ashley's Reality Roundup was the first to report Matt taking the test.
Adding, “It was filmed by MTV, so it will all play out on Teen Mom.”
