If you see Shia LeBeouf in a bar, it would probably be in your best interest to either leave, or steer clear of making any disparaging remarks towards him or his girlfriend’s mom.

The Transformers actor was caught on camera head-butting a man at a bar in South London after the man made comments about LeBeouf’s girlfriend’s mom. According to the video on TMZ, the 27-year-old LeBeouf gets in the man’s face and can be heard repeatedly (and loudly) saying, “What did you just say?”

LeBeouf then head-butted the man while two women can be heard yelling his name, trying to defuse the situation, according to the Huffington Post.

Shia has a history of getting into brawls and altercations at bars. He was involved in a fight at the same bar, Hobgoblin, back in 2012. In 2011, he was punched in the face outside of a bar in Canada after the two were kicked out of the bar.

To make matters worse, LeBeouf was recently under fire for plagiarizing dialogue from a Daniel Clowe story to use in his short-film, Howard Cantour.com.

Was LeBeouf out of line for sticking up for his girlfriend’s mother? Feel free to post your thoughts and comments below.
