The Hunger Games star Jennifer Lawrence has become anxious about tripping over on the red carpet since her tumble at the 2013 Oscars.

The 23-year-old Silver Linings Playbook star explained that she has a fear of falling flat on her face at important events.

Speaking to The Sun newspaper, Lawrence said: ''My mom taught me to laugh at myself. What else can I do? There are so many things that I do and say which come out wrong because I don't think before speaking. I make a fool of myself easier than anyone I know. But that's part of the way I was allowed to be when growing up. I get so nervous before going down red carpets - particularly after that fall at the Oscars.

''I've tripped at least a couple of other times, too. I managed to forget to thank both the director and producer when I went on stage, so I wonder what was worse? I had to walk down the stairs at the wedding of my older brother recently and thought, 'I cannot fall again. I just can't.''

Jennifer further explained that she is delighted her role as Katniss Everdeen in The Hunger Games has inspired young girls, adding: ''A lot of people have picked up on the fact that I don't diet and that it's better to be happy and healthy. That, again, is the way I was brought up. My mom never once said, 'I think you should lose weight.' I have had that said to me in Hollywood and I just ignore it.

''There are too many fashion police out there judging us all on looks and weight. One of the many things I love about my character, Katniss Everdeen in The Hunger Games is that although she is fit and strong, she's never thin.

''She's a great role model for girls in that she is tough and determined, yet also shows kindness and love.''
