Reality stars Farrah Abraham and Amber Portwood reportedly got into a physical fight during a taping of the Teen Mom OG season 7 reunion, according to E! News. The reason behind their fight was allegedly an off-camera comment made by Farrah's boyfriend Simon Saran about Portwood's fiancé, Matt Baier.

An insider who was in the audience spoke to The Real Mr Housewife blog about their fight and revealed, "All was going well during the reunion. Farrah was taping her segment and Simon's comments about other cast members came up."

The insider explained, "When Dr Drew mentioned Simon had called Matt a paedophile, it seemed like he was heading in the direction of an apology, claiming it was all in fun...However, Farrah piped in and said well he does kind of look like a paedophile."

Amber allegedly stormed onstage and started yelling at Farrah, revealed the source. "At that point things got out of hand. Amber stormed onstage and started yelling at Farrah. Michael, Farrah's Dad, got out of his seat and got in between Farrah and Amber and was yelling at Amber and calling her a bitch. Then, Matt came onstage and got in between Amber and Michael."

Adding how things got "suddenly physical" the source said, "Suddenly, things took a physical turn. All that could be seen was that Michael seemed to put his hand on Matt's threat and Michael went flying into the audience and Farrah was yelling at Amber to punch her. Amber tried and just missed hitting Farrah."

Maci Bookout allegedly tried to get in the drama as the source continued, "The other cast members were trying to get onstage. You could hear Maci screaming that she wanted to come on and was going to f*****g kill Farrah. They didn't get on, though, as security seemed to hold them back."

"The situation ended when security removed Matt and Amber from the stage. This was truly crazy to witness," the insider concluded.

Teen Mom OG stars addressed the incident on Twitter. Responding to a fan query about the reunion scuffle, Amber wrote: Matt went out there to get me [to] not fight...her dad got in my face so Matt the middle and Michael choked him so Matt knocked him on his ass. While...Simon sat on the couch the whole time lol..."

Farrah retaliated by tweeting a screenshot of a text with "Larry Mtv" on Twitter and wrote, "Thanks Larry &the 3 stooges I'm always working non stop and got sick but still showed up & set still wasn't ready for me- vile jealous liars"
