*TMZ is reporting that Katherine Jackson has decided that seven grandkids in her San Fernando Valley mansion is too many for her to supervise, and four of them need to move with their mother into a separate condo owned by the family estate.

Citing “sources with direct knowledge of the situation,” TMZ reports that Katherine has told Alejandra Genevieve Oaziaza — who is currently living at the estate, along with two of her kids by Randy Jackson and two others by Jermaine Jackson — that she and her children must move out next week.

Katherine, 79, is reportedly moving Alejandra, along with Jaafar, Jermajesty, Donte and Randy Jr. to a San Fernando Valley condo owned by the estate.

“We’re told the move was prompted by the stun gun incident last month,” states TMZ. Jaafar, 13, bought a stun gun online and fired it in the house, the Web site reported. Sources say Jaafar pointed the gun at two of Michael’s kids, but the family denies that.

“The L.A. County Department of Children and Family Services came to the estate, took the gun and interviewed people in the home, and it became apparent seven kids were too much for Katherine to handle,” TMZ reports. “So as of next week, Prince, Paris and Blanket will have the run of the mansion, unobstructed.”
