Actor Shia LaBeouf clashed with Tom Hardy on the set of their new movie The Wettest County In The World after a bad joke ended in a physical fight.
The Transformers star admits he struggled to bond with Inception actor Hardy while shooting the upcoming Depression-era crime drama and tensions came to a head one day when they became embroiled in a backstage brawl.
LaBeouf claims the tussle was a one-off and Hardy "never did that roughhouse stuff with me again".
But that wasn't the only issue LaBeouf had with his co-star - he despised hearing Hardy and their fellow colleague Jason Clarke boast about their expensive sports cars.
LaBeouf, who frequently banks $15 million (£9.4 million) pay cheques for his roles in box office blockbusters, like Michael Bay's Transformers and Indiana Jones & the Kingdom of the Crystal Skull, insists he has "no interest" in spending his money on expensive toys and gadgets and claims he feels "real shame" over his growing wealth.
So he found himself gritting his teeth as Hardy and Clarke chatted about their pricey rides.
In a candid interview with Details magazine, he says, "At this point I have enough money to live 25 lifetimes. You couldn't spend the money I've accrued now. (But) I have no interest in the materialistic bulls**t money can buy.
"They're talking about Ferraris and s**t, like it's a cool car. If Clarke pulled up in a Ferrari right now, my idea wouldn't be, 'What a cool f**king guy!' It would be, 'Look at this clown.' I think the fact that I despise that stuff keeps me safe. I hang on to my dirt. I like my dirt."
