Los Angeles: Actor Jennifer Lawrence said she channels her rude lady avatar when she finds herself surrounded with her fans. The 27-year-old actor said it is only way of self-defence for her. "Once I enter a public place, I become incredibly rude. Thats my only way of defending myself... "I take my dog to the park all the time, to Central Park. As soon as I meet her in the park, we're f ed," Lawrence said.
