Michael Jackson's sister LaToya Jackson has concerns about Michael's former nanny, Grace Rwaramba, who worked for Jackson for 17 years until she was fired in 2008.
Rwaramba was the only nanny Jackson's three children -- Prince Michael, 12, Paris Katherine, 11, and Blanket, 7, -- ever knew until her employment was terminated by Jackson. But she's back in the fold now after Michael's mom Katherine Jackson invited her to visit the children.
A judge granted Michael's mom Katherine temporary custody of the kids after the King of Pop died suddenly of a cardiac arrest on June 25.
"The family has mixed feelings about her," LaToya told British newspaper The Mail on Sunday. "Mother says [Grace] wants to be with the kids but I warned her to be careful. It's not like the children like or dislike her. They like everyone. Mother is gullible and feels sorry for her."
LaToya said Rwaramba just showed up one day to see the kids and she never left.
"I have a lot of questions about Grace," said LaToya, who is convinced her brother was murdered by people in his trusted inner circle. "She was instrumental in keeping the family away. All of a sudden she is back, listening and watching the family. I think her behaviour is odd."
