Michael Jackson has secretly wed his children's long-serving nanny, according to shocking new U.S. reports. Despite denials from the pop superstar's camp, America's National Enquirer has printed copies of a new real estate document, in which Jackson states he's married. And now sources close to the King Of Pop have confirmed Jackson wed 40-year-old Grace Rwaramba in Las Vegas earlier this year (07). A source tells the Enquirer, "Grace... is one of his dearest friends. She is one of the few people who stood by his side through all of his problems - including the child molestation trial in 2005." If true, this is Jackson's third marriage. He was previously wed to Debbie Rowe and Lisa Marie Presley.
