Jackson KidsMichael Jackson's two oldest children -- Prince Michael, 13, and Paris, 12 -- began their studies at a traditional school last Wednesday -- their first experience outside of homeschooling. But before they could hit the books like "normal" kids, Prince and Paris had to first win over their skeptical grandmother, Katherine.

A family member close to the situation tells PopEater that Paris and Prince's legal guardian protested the idea of sending the sheltered kids to school, feeling their father would have disapproved. However, one of Jermaine Jackson's sons stepped in and encouraged Katherine to allow Prince and Paris to move away from homeschooling.

The King of Pop's eldest children are attending The Buckley School in the San Fernando Valley and a parent at the school tells PopEater that things are anything but "normal" when the famous kids are there.
