Shia LaBeoufwas reportedly involved in an altercation with a man at a South London pub last night (January 16).

According to TMZ, the ex-Transformers star was caught on camera clashing with the unknown individual after arguing with him in the early hours of the morning while drinking at the Hobgoblin establishment.

In footage obtained by the US website, LaBeouf can be seen confronting a bald man - with the scuffle allegedly happening over the actor's girlfriend's mum.

The 27-year old - who is wearing a white baseball cap in the clip - is heard yelling: "What are you saying about my girl’s mum? Are you f***ing kidding me bro? What did you just say? What did you just say?”

As things get more heated between the pair, a girl - thought to be his partner Mia Goth - is heard shouting Shia's name in a bid to cool their debate.

TMZ adds that after their fight, LaBeouf tried to justify his actions, insisting her was "super normal" and saying he gets angry when "people s**t on my girl's mum."

The star is yet to directly comment on the reports.
