A number of country stars are helping St. Jude Children’s Research Hospital launch its new We Won’t Stop campaign, including Miranda Lambert, Darius Rucker, Tim McGraw, Reba McEntire, Thomas Rhett, Kelsea Ballerini, Little Big Town, Dan + Shay, Florida Georgia Line, Gabby Barrett, Lady A and more.

The stars are encouraging their fans to make a monthly commitment to St. Jude as a Partner in Hope to receive a We Won’t Stop t-shirt. Donors can then post a photo wearing the shirt on social media using #StJudeWontStop until no child dies from cancer.

St. Jude Children’s Research Hospital, located in Memphis, Tenn., is one of the world’s premier pediatric cancer research centers. Thanks to generous donors, families never receive a bill from St. Jude for treatment, travel, housing or food.
