The 29-year-old and his girlfriend were filmed fighting outside a hotel in Germany on Friday night, where it appears Mia was desperate for Shia not to leave for the airport.
As Mia takes his backpack away from him, Shia can be heard pleading for her to give it back to him, saying: ‘I don’t wanna touch you. I don’t wanna be aggressive/ This is the kind of s*** that makes a person abusive.’
After a local offers to drive the Transformers star to the airport so he can fly to Texas, Shia tells them about the incident, saying: ‘If I’d have stayed there, I would have killed her…It’s hard bro - really f***ed up - in your heart.’
Capturing the incident on camera, one of the locals tells him that 'women are hard' as Shia continues to explain the situation, adding that he 'has no home' and indicating that the bag on his back is the only home he has.
The actor, who met Mia on the set of film Nymphomaniac, can then be seen trying to FaceTime his former co-star Megan Fox from the car, though she doesn’t pick up.
And shockingly, according to German tabloid Pure Stars, Mia has been seen out and about this week with a black eye - though no physical altercation was seen between the actress and her boyfriend.
Mia and Shia have been dating since 2012, and sparked engagement rumours when the 22-year-old was seen sporting a large diamond on her finger.
