Actress Uma Thurman is full of admiration for Shia LaBeouf's bizarre paper bag stunt, insisting he could be starting a brand new fashion trend among camera-shy stars.

The Transformers actor has sparked fears for his health in recent weeks following a series of odd incidents which culminated at the Berlin International Film Festival in Germany earlier this month (Feb14) when he walked the red carpet with his face covered.

LaBeouf was wearing a paper bag with the words 'I am not famous anymore' scrawled across the front ahead of the premiere of his new film Nymphomaniac, but Thurman was impressed with his stunt and hopes he is breaking new ground for celebrities.

The Pulp Fiction star says, "I don't know how to interpret the paper bag. Maybe I'm jealous. There are many times when I wish I could have put a paper bag over my head. It could be a new trend... it's the paper burka!"

The actor was back in the bag this week (beg10Feb14) for a bizarre live art installation in Los Angeles. LaBeouf has been sitting in a pop-up gallery meeting visitors while wearing the now-infamous bag on his head.
