Teen Mom OG star Amber Portwood and her on-again, off-again fiance, Matt Baier, will reportedly hash out their issues on the eleventh season of Marriage Boot Camp: Reality Stars.

According to a source, "Matt and Amber are still together and still living together," Us Weekly reported in light of the couple's roller-coaster romance and recent allegations of domestic abuse. "They're trying to work things out."

Portwood and Baier would be following in the footsteps of Teen Mom OG co-star Farrah Abraham -- who is currently starring on the WE tv reality show's Family Edition with her parents Debra and Michael Abraham -- as well as Teen Mom 2's Kailyn Lowry, who filmed episodes with her ex-husband Javi Marroquin but couldn't salvage their relationship.

Portwood, 27, hinted at her upcoming reality TV stint Sunday on Instagram, informing her followers that she'd be working in Los Angeles for 18 days.

Portwood was shown calling off her wedding to Baier on Monday's episode of Teen Mom OG after he gave her co-star, Catelynn Lowell, a Xanax. Baier has reportedly struggled with substance abuse issues, and he further upset Portwood by calling her a "psycho" when she refused to elope with him in Las Vegas.

The couple has been dating for more than two years, according to Us, and recently considered an offer from Vivid Entertainment to star in a sex tape together.

"As business people, Amber and I need to consider every offer we get from every different angle," Baier, 46, told Us in May. "Amber and I gained a whole new respect for that industry that we didn't have before."

Portwood has an eight-year-old daughter, Leah, with her ex Gary Shirley, who was previously featured on Teen Mom as well as 16 & Pregnant.

Marriage Boot Camp currently airs on Friday nights at 9PM ET on WE tv.

In addition to Abraham, the cast is comprised of Chad "Ochocinco" Johnson, Michael "The Situation" Sorrentino, Kendra Wilkinson, and their respective family members.

Teen Mom OG airs on Monday nights at 9PM ET/PT on MTV.
