Last month Justin Bieber promised the students of Whitney Elementary in Las Vegas that he would put on a holiday concert at their school, and not only did he keep his word, but he also wrote them a check for $100,000 when he paid them a visit on Friday!

Justin teamed up with pal Ellen DeGeneres to help the kids, and she also surprised the school with a $100,000 donation courtesy of Target. In November, Ellen brought attention to the fact that over 70% of the children enrolled at Whitney don’t have permanent homes, and she presented Principal Sherri Gahn with a brand new library worth $200,000. We love it when celebs put their money where their mouths are!
