Sources linked to Katherine now tell media, Katherine wants the money because she incurs various expenses when she spends time at Janet's property.  Our sources say the expenses include food, cable, utilities, Internet, travel and even toilet paper.

It was earlier supposed the claims are related to partial mortgage payments on the property.

But insiders told that Janet never spends time at the Las Vegas house and bought it specifically for the use of her mother, who is the legal co-guardian of the late King of Pop's three children, Prince, 15, Paris, 14, and 10-year-old Blanket.

“Katherine never asked the executors to pay the mortgage or any other costs associated with Janet's home in Las Vegas. The family allowance covers travel and housing expenses for the four beneficiaries of Michael Jackson's estate, and are relatively inconsequential,” Katherine Jackson's lawyer, Perry Sanders, told a media tabloid.

A hearing is pending on the request, which was submitted before the Together Again singer and some of her siblings called for the executors of Michael's estate to resign, claiming his will was a fake.
