Louisville native and actress Jennifer Lawrence is giving back big to her hometown Kosair Children's Hospital.

Here's the announcement of the foundation from Lawrence herself.

The new cardiac intensive care unit is part of a complete renovation of the "Just for Kids" Critical Care Center. The hospital's heart center is the only pediatric cardiovascular program in Kentucky where more than 5,000 children visit and nearly 18,000 procedures are performed each year. The hospital also serves southern Indiana.

As stated above, the actress is challenging the community to match her $2 million donation as part of the Heart Center Challenge.
