Rupert Grint and Tom Felton gave a celebrity message airing on Christmas day to help support a charity called "Text Santa." It is a new television show on ITV that aims to raise awareness and money for people who are most vulnerable during the holiday season. In the clip below, Rupert and Tom (at 2:00) encourage viewers to donate and help the charity continue putting smiles on the faces of families in need. And the best part is, you can still donate! Donations end January 6th. Click here to find out more about how you can help.
