Amber Portwood and Matt Baier attended the latest "Teen Mom OG" reunion filming days ago and during the event, Portwood reportedly came to blows with her longtime co-star, Farrah Abraham. After feuding for months both on the show and off, Portwood and Abraham allegedly engaged in a physical altercation after Abraham poked fun at her boyfriend's recent comment about Baier being a pedophile.

On October 23, the Real Mr. Housewife shared details from Saturday's taping. According to the report, Abraham's boyfriend, Simon Saran, appeared to be ready to apologize for his pedophile comment, which was reportedly made on his social media page, but before he could do so, Abraham cut in and said, "Well, he does kind of look like a pedophile.”

Amber Portwood stormed the stage during Farrah Abraham's 'Teen Mom OG' reunion segment

When Amber Portwood heard what Abraham had to say about her fiance, she stormed the stage and began to yell at her co-star.

Right away, Abraham's dad, Michael, got in between the two women, likely in an attempt at mediating the situation. In turn, Portwood's fiance, Baier, got in between Portwood and Abraham's father.

At that point, things took a physical turn between them cast as Michael appeared to put his hand on Baier, Baier reportedly went flying into the audience. Meanwhile, Abraham began screaming at Portwood and encouraging her to punch her, which she allegedly attempted to do.
