"Hunger Games" franchise star and Oscar winner Jennifer Lawrence has donated $2 million to a children's hospital in her native Kentucky and urges others to join the campaign. She made a surprise visit to the Louisville facility right before Christmas  and just recently announced the establishment of the new Jennifer Lawrence Foundation Cardiac Intensive Care Unit.
