Rebbie Jackson, the unklnown Jackson sister, is rumored to have been tapped to take control of Michael Jackson’s orphaned children. The investigation into Michael Jackson’s drug overdoses, plastic surgeons, and doctors continue even as the Jackson family tries to band together to sort out the mess left behind. Other drama includes Janet refusing to appear at the family memorial performance at the end of August, and the constant bickering amongst the surviving Jackson’s over the millions (some say billions) of dollars Micheal Jackson left behind.

Multiple sources in the Jackson family tell us — even if Katherine Jackson gets custody of Michael Jackson’s kids — Michael’s big sister Rebbie Jackson will raise the children.

The 59-year-old singer, who shares a home in Las Vegas with her hubby of over 20 years, has kept a low public profile, but privately she has been deeply involved in the lives of Michael’s children.

We’re told Rebbie is currently living with Katherine at the family’s Encino home and is caring for the kids day-to-day. As for the kids … they all adore her.
