Amber Portwood's fiance, Matthew Baier, has been caught trying to hook up with Farrah Abraham, and making shocking insults against Kailyn Lowry's look, but that isn't stopping the Teen Mom OG star from marrying him.

In a new interview, Baier is speaking out about his and Portwood's upcoming wedding, which will take place on Oct. 10, and include a number of Portwood's MTV co-stars.

“Amber plans to have her fellow Teen Mom stars in the wedding party,” Baier told Life & Style on Wednesday.

According to the report, Maci Bookout, Catelynn Lowell and Farrah Abraham will all be standing at the altar with Portwood, despite Baier's previous tweets about Abraham.

“They are all so close and have been through so much together,” Baier told the magazine.

Just weeks ago, after Baier was accused of having five secret children during an episode of Teen Mom OG, Portwood defended her soon-to-be husband.

"There have been many stories and allegations surrounding Matt's past," Portwood told MTV News. "Just as my own journey has proven, people make mistakes and should be given a second chance without being judged solely on those choices. We are happy and focused on building our future together."

"I can say that today we're in a great place," she continued. "That was a few months ago. Matt still says he has five kids. The thing I always go for me to is if he has five, why the hell wouldn't he tell me if he has seven?"
