School has started, and the new kids in class are Prince and Paris Jackson. Michael Jackson's older children, who have been home-schooled up until now, are now attending The Buckley School in California's San Fernando Valley. After the superstar's death in June 2009, their grandmother Katherine Jackson took over custody, and she is sticking to her promise to send the kids to school. Katherine enrolled the siblings (Prince is 13 and Paris is 12) in the exclusive prep school where they began class on Wednesday. The King of Pop's youngest child, Blanket, 8, will continue to be home-schooled. Other celebrities who walked the halls of Buckley include Matthew Perry, Nicole Richie and Alyssa Milano.
