Amber Portwood and Matt Baier's October 2017 wedding has officially been called off.

Following rumors of cheating, secret children and more, Portwood has confirmed that she is no longer planning to get married to her controversial fiancé.

Portwood caught Baier hitting on her Teen Mom OG co-star, Farrah Abraham, on Twitter before they began dating.

Although many would argue that Portwood had many reasons to cancel her wedding before last week's episode of Teen Mom OG, she claimed that the final straw came after she discovered Baier had given her co-star, Catelynn Lowell, a Xanax pill to help calm her nerves.

As some may know, Baier is a recovering drug addict and the fact that he had a Xanax pill in his possession was extremely concerning to Portwood.

"It was pretty much the straw that broke the camel's back," Portwood, who is five-years sober, explained to Us Weekly on Thursday "We're not together now."

Although, there may be hope for a future reunion and currently, the couple is filming WEtv's Marriage Boot Camp.

"I think therapy in general would help," she explained. "There's a lot that needs to be worked on for us to even think of being together. He hasn't been the best. He's just met a person that doesn't deal with his s--t. But he's also met a person that he really is in love with and doesn't want to let go."

"At this point, I told him it's pretty much up to him to save this relationship," she added.

To see more of Amber Portwood, Matt Baier and their co-stars, tune into the season six finale of Teen Mom OG, which airs next Monday night at 9 p.m. on MTV.
