Forget about arguing with her parents or on-off boyfriend and co-parent, "Teen Mom" star Amber Portwood is now fighting total strangers. According to Radar Online, while at an IHOP in Indiana, Portwood engaged in a physical fight with another female patron of the restaurant -- a fight which she reportedly instigated.
"She was drunk, and there was another girl in the restaurant who had been drinking too and apparently said something about Amber to her friend," a source told Star magazine. "She told the girl, 'You don't know anything about me! I'm gonna whup your ass!' They just attacked each other."
And Portwood may have a tough time getting out of this one. The entire incident was caught on camera -- showing Portwood inciting the attack, in which punches were thrown and hair was pulled.
But this isn't the first time Portwood has gotten physical on camera. In 2010, Portwood was charged with domestic battery after she was shown slapping Gary Shirley, the father of her child, on their MTV reality show.
