John Edwards meets Hannah Montana:

On Thursday, Cyrus and her brother Braison rode the rides at the Magic Kingdom and Epcot. While in line for the Test Track ride, Cyrus ran into Edwards and his three children. (The senator’s youngest two children, Emma Claire and Jack, are Hannah Montana fans who were super eager to meet the star.) “She chatted with them about all the rides and attractions they saw at Walt Disney World,” a source close to the singer tells PEOPLE. “It was a sweet moment.”
