gracenanny230fix.jpgX17online can report exclusively that the Jackson family suspects the children's nanny Grace Rwaramba is the leak from within their Encino home, who made the initial call to the L.A. County Department of Children and Family Services. She's also suspected of spilling information to a tabloid website.

Our Jackson family source tells us that "Grace is trying to get custody of Michael's kids while trying to paint Katherine as an unfit guardian. She's throwing it in Katherine's face! The children absolutely despise Grace."

The source tells us Michael Jackson fired Rwaramba five times. Once the singer died, the nanny made her return to the Hayvenhurst home and was kicked off the property by Michael's younger brother, Randy. Sources tell us that Katherine is afraid to get rid of Rwaramba because she has been threatening to write a tell-all book.

The recent stun gun incident involving Jermaine Jackson's 13-year old son Jaafar has brought to the forefront the strained relationship between the former nanny and the Jackson family.

A video showing Jaafar Jackson pushing his 9-year old brother Jermajesty was sold to a website recently and X17online has been told that the Jackson family believes Grace Rwaramba released this tape.

Since the stun gun story "leaked," Rwaramba has been mysteriously absent from the home. Jackson family sources tell X17 that her days are numbered.
