La Toya Jackson is suspicious of her late brother Michael’s nanny, Grace Rwaramba.

Rwaramba worked for the King of Pop for 17 years, caring for Prince Michael, 12, Paris, 11, and Blanket, age 7, before she was dismissed by the King of Pop last year.

Grace has been looking after the kids alongside Jackson’s mother, Katherine, since the singer’s death last month, but La Toya is uneasy about the nanny’s presence, telling British newspaper the Mail on Sunday: “The family has mixed feelings abouther. Mother says she 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.”

“I heard Grace liked Michael but he didn’t like her,” La Toya adds of the reports that Grace and Michael were romantically involved. “He let her go last Christmas. I have a lot of questions about Grace. She was instrumental in keeping the family away. All of a sudden she is back, listening and watching the family. I think her behavior is odd.”
