Jennifer Lawrence, the genetic template for America's army of Cool Girl clones, revealed her secret Achilles' heel to David Letterman last night: She may have the singing voice of an angel, but it's a drunk, possibly dying angel.
But because she's super-cool and so laid back, it truly doesn't matter that her "Holly Jolly Christmas" sounds like Louis Armstrong meeting Burl Ives in a desperate fight that only one can survive. There is nothing she can do that would make you stop liking her, with the possible exception of aging normally.
During the same appearance, she walked out of her interview, did a Chris Farley impression, and eventually just took over Letterman's desk. What a cool girl.
