We really love this girl. Not only has she proven how great her acting skills are, she also has one of the biggest hearts in this world.

During the London premiere for "The Hunger Games: Catching Fire" on Monday, Jennifer showed how much she cares for her fans. The 23 year-old Oscar winner stopped in the middle of her red carpet duties and greeted 15-year-old Jessica Hambly, who was seen crying as J.Law walked past.

Hambly is from Bransholme, England, and she suffers from mucopolysaccharidosis disease, a metabolic disorder that makes the joints of the body weaker, nerves less effective, and the heart and lungs do not work as well as they should.

The two chatted, hugged and took a picture with each other.

"Although my condition has gone wrong and got worse, its limitations are still minor things like not being allowed on fast or rockety rides but that's not important to me. What is important to me, however, is time and memories and although I will never be a granny, I measure life in what you did, not how long you lived!" Hambly said.
