Amber Portwood Admits The Disturbing Reason She Dumped Ex-Fiancé Matt Baier

From cheating accusations to drug scandals, Amber Portwood had plenty of reasons to dump controversial fiancé Matt Baier over the years. But what made the Teen Mom OG star finally kick him to the curb? In an Instagram live video, Portwood reveals she dumped Baier when she heard the comments he made to producers behind-the-scenes.

“It shocked me how he said those things behind my back and I didn’t know,” she said in the June 15 video. “He's such a good person to me sometimes, but when I saw what he was saying behind my back it shocked me and opened my eyes.”

As RadarOnline.com reported, Baier bashed her to a TMOG producer when she refused to marry him during a getaway to Las Vegas because her brother advised her not to.

“I will not marry her,” he ripped. “I will not marry her now, ever! I’m not gonna let her brother dictate my life. That f*****g f****t. She wants to marry her brother. That’s who she wants to marry. F**k her. She just humiliated me on TV. I’m done.”

He continued, “I will fake this the rest of the day. But I am done with her f*****g psycho a**.”

He then told a producer to “give oral pleasure” to whoever possible to keep the “Amber and Matt wedding thing off TV."

His tirade continued on a later episode, when Portwood slammed him for giving co-star Catelynn Lowell Xanax for her anxiety when he is supposed to be sober.

“Now there’s rumors, everybody’s talking about how Matt was f****d up yesterday and that he’s back on drugs,” he said to a producer. “She wakes me up this morning, ‘We’re not getting married. You’re a f*****g junkie.’ I’m done with this.”

Portwood broke off their engagement in May after sources revealed that he failed a lie detector test about cheating on Portwood.

Although an insider told RadarOnline.com that the reality stars are “still living together” and that she has “not made any final decisions just yet,” she revealed over Instagram live earlier this month that they are not together.

But there may still be hope for the toxic couple, as RadarOnline.com exclusively reported that they will appear on Marriage Boot Camp Reality Stars.
