Jennifer Lawrence's brothers used to lock her in the basement with the dogs.

The 21-year-old 'Hunger Games' actress says her two older siblings used to take great pleasure in tormenting her.

She said: ''I've got scars all over my body. The best part - they would fight each other over who could fight me.

''When I was doing the gymnastics phase, they used to pin my feet back behind my head - I can't do this anymore - and then they would get our dachshunds and put peanut butter all over my face.

''We had three dachshunds and then the dogs would do this [go crazy licking]. And then they'd shut the door, lock me in the basement with dachshunds.

''And now - karma! - I go on talk shows and tell everybody. I win!''

Appearing on 'The Late Show', host David Letterman joked: ''I'm going to make two calls, Jennifer. The first one will be to Amnesty International, and the second one will be to Dick Cheney.

''I think we have something here. It might replace water boarding, that little dachshund deal.''

The Oscar-nominated star - who admits she eats an ''awful'' lot of sweets - also landed herself in hot water when she and best friend Zoe Kravitz raided her rocker dad Lenny's minibar.

Jennifer told US Weekly: ''We just went to her dad's hotel room and got Gummi Bears and HBO. We racked up so many charges. Mr. Kravitz was like, 'Did you guys order a lot of room service?'''
