Amber Portwood has reportedly called off her October wedding with fiancé Matt Baier. The Teen Mom OG stars have been dating for two years and are still living together despite "few bumps in the road."

A source told Us Weekly, "They are still together and living together but there have been a few bumps in the road. The fall wedding isn't happening. Amber got cold feet after a series of red flags."

"For the time being, Matt and Amber's engagement is on hold. They are working on their relationship," the source added.

Neither of the MTV stars has commented on their delayed wedding plans as an E! News report says that the couple has decided to hold their fall wedding. An insider told the outlet, "For the time being, Matt and Amber's engagement is on hold. They are working on their relationship."

A source was quoted as saying, "A lot has come out through the course of filming and from various online stories. That has added extra pressure and made things difficult.They've both been open about their personal struggles, but it hasn't been easy when their lives are under such heavy scrutiny. Despite their issues, they are still living together and are hopeful things can be fixed."

Recently speculation about Portwood abusing her fiancé was in the news after a photo of Baier's bruised face went viral. However both of them have denied those reports, but there is definitely trouble in paradise.

In a recent episode of Teen Mom OG season 7, Portwood broke down on camera while trying on wedding gowns. She explained to an MTV producer, "We've just been through a lot these past few years, [and] that has really shut me down from the wedding."

Revealing that she doesn't trust Baier and that her depression was caused by him, she told the cameras, "When you put your trust in somebody ... that's what a relationship is built on. You get to a good place in life, and you can love each other and want to be with each other for the rest of your life, and still not trust each other. That's what messes up everything."
