Jennifer Lawrence has misplaced her Oscar.

The 23-year-old actress won the prestigious Best Actress Academy Award earlier this year for her role as Tiffany Maxwell in 'Silver Linings Playbook', in which she starred alongside Bradley Cooper.

But the down-to-earth star insists the accolade hasn't changed her life and she's doesn't even know where the statuette is at the moment.

She told Spanish magazine AccionCine: ''I don't know where it is. I think it might be in Kentucky. I hope it's in Kentucky. If not, it's gone. I don't have it.''

The Hollywood star - who also earned an Oscar nomination for her unflinching performance as Ree in the 2010 flick 'Winter's Bone' - is now getting ready for the release of blockbuster sequel 'The Hunger Games: Catching Fire'.

Jennifer plays all-action heroine Katniss Everdeen but admits she was worried about developing trench foot when she had to shoot some tricky scenes in a swamp with co-star Josh Hutcherson.

She revealed: ''That was the worst scene. We were in the swamp for days. I'm paranoid about everything and Josh was talking about trench foot and toe fungus when we were in the swamp. He was like, 'Yeah that's what happens when your feet are too wet.' Our feet were wet for 73 hours. I was having a meltdown.''

And when she's not panicking about scenes she's making manly jokes with the boys.

She said: ''As soon as someone farts, I think it's hilarious.

''This is something my brothers did that now the boys at work are obsessed with.

''You cup it, then you throw it in someone's face and say, 'Take a bite out of that cheeseburger!' ''
