London - Shia LaBeouf has been involved in a bar fight.
The 'Nymphomaniac' actor - who is dating his co-star Mia Goth - appeared to headbutt another man during a row at the Hobgoblin pub in New Cross, south London last night (16.01.14) in an altercation about his girlfriend's mother.
In video footage obtained by TMZ, the actor - wearing a white baseball cap - can be heard shouting: "What are you saying about my girl's mom? Are you f**king kidding me bro?"
In the clip, a woman can be heard shouting the actor's name in an attempt to calm him down.
After the actor - who can also be seen screaming in the man's ear - was restrained by one of the two women he was with, the other female said to the guy: "Don't be sarcastic with us again. Don't even play smart."
This isn't the first time the 27-year-old star has got into a row in the Hobgoblin pub.
In November 2012, he fought with a drinker after someone stole his hat.
Shia had been in good spirits and happily posing for pictures with fans, but the mood turned sour when a fellow drinker "jokingly" swiped his baseball cap and refused to give it back.
One onlooker said at the time: "No one could believe that a well-known Hollywood star had rocked up at a bar in dingy south London. Everyone was getting photos taken with him.
"The row started when this guy took his hat. I think he was joking, but Shia didn't like it.
"The guy just took it off him and wouldn't give it back. He tried to get it back and they ended up tussling."
The 'Transformers' actor was also involved in two bar fights in 2011. - Bang Showbiz
