Shia and his girlfriend Mia Goth get into a fight in Germany, in public, and there's video footage.

Not sure what they were fighting about, but in a video released by Entertainment Tonight, they're arguing in the street, and Shia asks her to give him his backpack.  He says, "I don't wanna touch you.  I don't wanna be aggressive.  This is the kind of crap that makes a person abusive."

That's when some locals intervene and offer him a ride to the airport.  Shia later tells them, "If I'd have stayed there, I would have killed her."  He was smoking an e-cigarette, talking about guns and tried to Facetime with Megan Fox!  Later, he tells the men he would repay them for the ride by hosting them if they ever come to L.A.
