Amber Portwood revealed shocking details about her past relationship with Matt Baier on last night's new episode of "Teen Mom OG." While the couple parted ways months ago in real-time, fans are just now seeing the end of their relationship play out on the MTV series, and on Monday night, Portwood shockingly accused Baier of being responsible for the absence of $120,000 of her hard-earned money.

“Within the last three years we’ve been together, tallying everything up, it’s been $120,000 that I have no clue where it’s went," Amber Portwood revealed to her brother, Shawn Portwood.

She also said that she feels like Baier is a pathological liar and accused him of sending his daughter money that wasn't even his.

Amber Portwood was offended by Matt Baier's daughter

According to a report by Hollywood Life on December 5, Amber Portwood was offended when the daughter of Matt Baier suggested that he was facing hardships and criticism due to the way he had been portrayed on "Teen Mom OG." So, in turn, Portwood informed her former fiancé that if he wanted to listen to his daughter, he should pack his bags and leave their previously shared home for good. Baier then followed Portwood's recommendation, but not before reminding the reality star that the home was just as much his as it was hers.

Matt Baier also accused Amber Portwood of being on drugs. However, the recovering addict quickly shot down his shocking allegation and encouraged him to look at her pupils. She then told him to get the heck out of her house and called him a “f***ing b****.”

Where is Amber Portwood now?

As Matt Baier adjusts to married life with his new wife, Jennifer, who he married at the end of last month, Amber Portwood and her new boyfriend, Andrew Glennon, are currently awaiting the birth of their first child, the second for Portwood.

As "Teen Mom OG" fans will recall, Portwood already shares an older child, nine-year-old Leah, with her former boyfriend Gary Shirley. Portwood and Glennon's new baby is expected to arrive sometime next year but the couple has not yet confirmed an exact due date for the reality star.
