Britney Spears' dad, Jamie Spears, made a rare appearance in a wheelchair at his granddaughter's graduation over the weekend, two years after having his right leg amputated. Jamie, 73, was spotted wearing a gray suit as he sat with his family at Maddie's high school graduation on Friday, May 8, in photos published by Page Six. His ex-wife, Lynne Spears, was also in attendance, as well as daughter Jamie Lynn Spears, her husband Jamie Watson, and their daughter Ivey, 8. Jamie Lynn, 35, could be seen crying in the audience as the proud mom snapped photos of Maddie, 17, during the ceremony.
