Amber Portwood and Farrah Abraham were engaged into a nasty fight while off the camera during the taping of Teen Mom's latest season.

Well, according to sources, the fight does not only involve the two reality TV stars but their boyfriends, Simon Saran and Matt Baier.

Sources claimed that that Simon cast the first stone by having a trash talk against Amber's boyfriend, Matt calling him a 'pedophile,' Oxygen reported.

"When Dr. Drew mentioned Simon had called Matt a pedophile, 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 pedophile," a witness said.

More people took sides including Michael, Farrah's dad trying to get in between the two women but at the same time calling Amber a 'bitch' which made Matt got on stage to rescue Amber.

The situation then got uncontrollable and physical with Michael and Matt fighting separately with Amber and Farrah. 

Then again, The Hollywood Gossip is skeptical as to whether the fight is real or have a motive behind it to promote the Teen Mom: OG reunion show. The news outlet, further mentioned why the  MTV reality TV franchise welcomes Abraham, somebody 'shunned by society' as if promoting her behavior.

There were also speculations that the fight is scripted so Farrah can then decide to get her 7-year old daughter, Sophia from the show. Then again, something will be missing if the show will not feature kids in it.

Meanwhile, Maci Bookout and Catelynn Lowell are also not getting along well with the 25-year old reality TV star as she came in late to the reunion.

"Maci proceeded to tell him that she has been doing this show for eight years, and every year the women arrive on time and do their jobs," a source said. 

Maci asked the host, Dr. Drew Pinsky where Farrah as she cannot be found on stage. This made Maci mad at her.
