Late Night: Jennifer Lawrence says she hates herself, is a 'troll' "Hunger Games" star Jennifer Lawrence may be poised on the cusp of mega-fame, but clearly she hasn't let it go to her head. During a visit to "The Late Show" on Tuesday, Lawrence was endearingly nervous and self-deprecating. So much so, in fact, that host David Letterman suggested she might need psychiatric help. I hate myself. Don't go see the movie. I'm a troll," said the lovely, blond, decidedly un-trollish actress. I think the movie's great, but their biggest mistake is me. Letterman was baffled by Lawrence's self-loathing. "I don't like looking at myself," he said, "but myself it's genuine; I'm unpleasant looking. You're a lovely woman and a fine actress. Lawrence also told Letterman about her red-carpet phobia. It's so scary. I end getting so nervous that I get like now, and I get really hyper, so then I go interviews and I'm like, 'I'm a Chihuahua! I'm shaking and peeing.' And then afterwards I'm like, 'I just talked about peeing on the red carpet.' It's just not a situation for a normal person! "I'd like to see you twice a week," Letterman joked as he pretended to jot down some notes. Exacerbating Lawrence's considerable anxiety are her handlers, who constantly make her aware of her appearance. "I make it halfway through the red carpet and somebody goes 'Suck in!' " she said. Then I wonder about the other half of the pictures, and it ends with me googling myself. Asked if her family was supportive of her career, Lawrence was, once again, hilariously candid. No! I mean ... yeah," she said, explaining how her older brothers urged her to take a few shots of booze before walking the red carpet. At first she resisted, but then gave in. And that led to 'I'm peeing in my pants' on the red carpet. It's quite a change from her childhood, when Lawrence's brothers used to cover her face in peanut butter and lock her in the basement with their family's three pet dachshunds. While plenty of starlets know how to turn on the self-deprecating charm when necessary, Lawrence's appearance was refreshingly human -- if slightly troubling.
