SHERMAN HEMSLEY: The El Paso Medical Examiner's Office in Texas says actor Sherman Hemsley died of natural causes and no autopsy will be conducted.

The star of the classic sitcoms "The Jeffersons" and "Amen" died Tuesday at his home in Texas. He was 74.

THE JACKSON FAMILY: A Los Angeles judge has appointed Tito Jackson's son T.J. temporary guardian of the late Michael Jackson's three minor children, TMZ reported.

Tito was Michael's older brother.

Their 82-year-old mother, Katherine, has been raising Michael's two sons and daughter in California since the pop icon died in 2009.

However, the matriarch has been staying with other family members in Arizona for more than a week and relatives are offering conflicting accounts regarding her health and whether or not she has been in touch with Michael's children.

Also unclear is whether Katherine Jackson wants to be in Arizona or is being held against her will by her children -- Randy, Janet and Jermaine and Rebbie -- who want her to get rid of the executors of Michael's estate, TMZ said.

Judge Mitch Beckloff temporarily stripped Katherine of her guardianship of Michael's children Wednesday and advised T.J. and his lawyer, Charles Shultz, to seek permanent guardianship of the late music legend's children.

Several media outlets reported Tuesday Stewart, 22, recently had a brief fling with director Rupert Sanders, who is 41, married and the father of two children.
