Louisville native Jennifer Lawrence brought some holiday and Christmas joy into the hearts of some sick children and their families in Kosair Children's Hospital in her hometown this season.

On Dec. 22, J. Law, who we're used to seeing waltz down red carpets in fabulous Dior pieces, was dressed casually and like a regular local when she paid the visit.

Donning a simple plaid shirt and dark jeans, her pixie was delightfully disheveled as she smiled while posing with patients and employees. It must have really made their day to have Katniss Everdeen come by.

J. Law is one of the biggest stars on the planet right now, and downtime with family is likely a luxury in which she rarely indulges. Still, she carved some time out of her schedule while at home to dispense a little cheer.

This is why we love her so much! Take that, Joan Rivers (who just criticized the Oscar winner without good reason).

Pictures from J. Law's visit are below.
