Jennifer Lawrence has admitted she turns into a scared "chihuahua" when she gets out of her comfort zone to make appearances at star-studded ceremonies.The 'Silver Linings Playbook' star won and was nominated for many top prizes for her role as Tiffany Maxwell in the comedy drama but she revealed the star-studded events leave her startled and uncomfortable.Speaking to The Sun newspaper's Fabulous magazine, she said: "I'm afraid I'm going to go through my whole life being scared like a chihuahua."It's not my comfort zone. Making movies is where I belong. I shouldn't be heard just talking."So, when I'm doing movies, I'm really happy. That's where I'm comfortable, that's my home. When you put me on a red carpet or on a stage, I turn into chihuahua Jennifer."The actress revealed she has no filter going from her thoughts to what she says to people.She added: "I have no control over what comes out of my mouth. I would probably turn into a mute if I read what I said".She also admitted she finds people "falling down" hilarious although she knows it's "terrible" to laugh.Jennifer joked: "I think when people run into things or people get hurt ... I know I just have a terrible reaction when I start laughing!"Then I ask if anyone is OK. But I just think people falling down and getting hurt is classic hilarity."One Direction have been forced into healthy eating regime.The 'Little Things' pop stars have reportedly been assigned full-time private chef Sarah Nicholas to help get more fruit and vegetables into their systems.A source told the Daily Mirror newspaper: "Sarah worked with the guys on their last tour and became like a surrogate mum for them all, particularly Harry [Styles]."She tries to offer the boys their favourite foods but healthier versions of them, using natural, often organic ingredients. They particularly like Mexican food."The switch comes with the boy band's "hectic" touring schedule meaning they need to start eating more nutritious meals to stay fit and healthy.The insider added: "With 1D's hectic schedule and gruelling lifestyles, it's essential they eat properly and start looking after themselves."This basically means Sarah has been charged with getting more fruit and veg down them, and staving off colds as much as possible. They're currently drinking loads of smoothies."The heart throbs recently discussed other dinner plans as Louis Tomlinson revealed David Beckham is his ideal party guest.He said: "I would have Natalie Portman because you need someone fit and maybe David Beckham, because I've always wanted to meet him.
