( CNN ) -- Is there anything Jennifer Lawrence ca n't do ? Actually , yes : She 's not the best when it comes to singing . The Oscar winner admitted to David Letterman on his `` Late Show '' on Wednesday that she has a huge fear of singing in front of other people , and it all goes back to the time she sang a holiday song in front of her school as an 8-year-old . `` I do not like singing in front of other people , '' Lawrence told Letterman . `` I 'm like , scarred from my childhood , because I had a mother who would tell me that I was amazing at everything and that I can do everything , but I ca n't . So I sang in front of the school , because it was like , ' I can do that ! I can do anything ! ' `` Lawrence claims that she has this `` tone-deaf Amy Winehouse voice , '' but when she broke into a rendition of `` Have a Holly Jolly Christmas , '' which is the song she performed way back when , Winehouse is definitely not who we were reminded of . Lawrence actually had to face her fear of singing for the latest `` Hunger Games '' movie , `` Mockingjay -- Part I , '' because she had to perform a song called `` The Hanging Tree . '' She still has n't heard her performance in the movie , but she knows that moviegoers will . `` Everybody 's told me that it 's me , '' she said , `` because I was like , 'will you guys please get Lorde to really sing it ? ' And they said no , it 's really your voice . '' We 'll find out how she sounds when `` Mockingjay -- Part I '' opens November 21 , but we can already bet it 'll be better than her take on Christmas carols .
