Actor Shia LaBeouf was caught on video head-butting an apparently drunken man at a South London bar Thursday, Jan. 16.
TMZ footage shows the 27-year-old Transformers star attacking a unidentified male in clear sight and in front of a group of people.
"What'd you say about my girl's mom?" LaBeouf screamed at the man, who is sitting with his head hanging low at the Hobgoblin pub. "Are you f-----g kidding me bro? What did you just say?"
LaBeouf then head-butted the man as two women -- including one pleading with "Shia!" -- tried to restrain the actor.
"Don't be sarcastic with us again," a British woman threatened the drunken man after LaBeouf was pulled away. "Don't even play smart."
It is unclear what the man said to spark the confrontation, which included LaBeouf screaming in the man's ear.
Hours later another video of the actor in the bar surfaced on the gossip website. He was telling a female patron he is just "a normal human being" and he's "not trying to s--t on anybody."
"I'm not trying to have, like, any more problems. Like, I'm really just trying to make peace," he said. "I'm a normal human being. Look, I accept what I get into to do what I love.'
"I'm a human being, you know what I mean? I'm super normal," he added. "Like more normal than most. When people wanna get hostile, or s--t on my girl's mom, or say things that are out of turn."
The fight comes less than a week after the Nymphomaniac star tweeted on Jan. 10, "In light of the recent attacks against my artistic integrity, I am retiring from all public life."
LaBeouf has been making controversial headlines lately regarding accusations of him plagiarising graphic novel writer Daniel Clowes for his short film, HowardCantour.com. He admitted to copying Clowes and apologized twice on Twitter and then in a sky-written apology.
Jim Carrey used the allegations as a way to take a jab at LaBeouf at the Golden Globes on Sunday, Jan. 12.
"Dying is easy, comedy is hard," Carrey said on stage before presenting American Hustle as a best picture nominee. "I believe it was Shia LaBeouf who said that. So young, so wise."
