Let's get physical! For over a month, multiple reports claimed that a fight broke out between "Teen Mom OG" stars Amber Portwood and Farrah Abraham. On Monday night, we saw what really happened and it was every bit as intense as was reported.

The cat fight started when Dr. Drew was interviewing Farrah and her off-and-on boyfriend Simon Saran. Simon is believed to have ignited the feud.

During the chat, Simon and Farrah trash talked and name called Amber's fiancé, Matt Baier. Simon even tried to play it off saying he "meant no disrespect" and "it was all in good fun". Dr. Drew didn't seem to find it funny that Simon called Matt a "pedophile," even asking if he was an online "troll." Simon counters that Drew and his critics needed to have a better sense of humor.

Just then, Amber stormed out from backstage, ready to get physical with Farrah. At one point, Amber tried punching the fellow reality TV star, but missed.

Then, Farrah's parents ran to the stage, as did Matt, a slew of producers and security.

Chaos broke out as Matt tossed Farrah's dad to the floor, promoting Farrah to say that Amber and Matt were "criminals." Matt and Simon also had to be restrained from attacking each other.

After the taping, Simon tweeted, "Recap of reunion: @amberportwood trotting around like a hippo. Matt and another senior citizen in a small scuffle. #teenmomog."

Once the air (and the stage) was cleared, Dr. Drew brought the rest of the ladies out on stage. But, the drama continued after Maci Bookout blasted Farrah for making MTV reschedule the filming.

Maci said it was unfair that the network bows down to Farrah's demands every time and she eventually hit her boiling point, ripping off her microphone and leaving. The rest of the "Teen Mom" followed suit.

Farrah is clearly public enemy No. 1 among her "Teen Mom" co-stars.
