Troubled Teen Mom star Amber Portwood started a fight with a complete stranger in an Indiana restaurant and it was caught on camera, Star magazine is exclusively reporting via Breaking Celebrity News.

In the still images from the video, obtained by Breaking Celebrity News, the 21-year-old mother is seen scrapping with an unsuspecting patron at an Andersonville IHOP on November 18.

"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.

"Amber instigated the fight. She told the girl, 'You don't know anything about me! I'm gonna whup your [expletive]!' They just attacked each other."

In the video footage, Amber can be seen in a white t-shirt, flailing her arms wildly at the other woman before charging her.

"There were a couple punches thrown and hair pulling, then they were separated," the witness said.

This is Amber's second time being caught on video attacking someone - the first was in a 2010 episode of the hit MTV show when she was shown hitting and slapping her ex and baby daddy, Gary Shirley.
