Janet has joined forces with mother Katherine and sister Rebbie to make sure Michael's will is upheld.
As another custody hearing for Michael Jackson's children was postponed on Friday, speculation has begun to spread about who will be the children's caretaker.

The most interesting scenario, among many, would see Janet Jackson stepping in to raise her brother's three children.

According to CBS News, a representative with tabloid outlet "Inside Edition" said that Janet has offered to help. Melanie Bromley, of Us Weekly said, "It's important for her to be there for the children." A rep for Jackson has yet to respond to a query made by MTV News on Monday (July 20).

The CBS report suggested Janet has banded with her mother, Katherine, and sister, Rebbie to improve the chances of Michael's will being upheld. In the will, he left custody of his children — Prince, Paris and Blanket — to his 79-year-old mother. Katherine has been granted temporary custody of the children and they have been living in the Jacksons' Encino, California, home since MJ's passing last month.

Currently, parties for Katherine and Debbie Rowe are in discussions after the latest custody hearing was postponed for a second time, a rep for Jackson's attorney, L. Londell McMillan, told MTV News.

Rowe is the biological mother of MJ's first two children — the identity of Blanket's mother still remains unknown. Although Rowe has not had much of a relationship with the children since giving birth to them, the onetime nurse reportedly wants to ensure the kids will be safe. According to TMZ, a source close to Rowe said her present involvement in the matter isn't over money; she is still reportedly receiving funds from Jackson's estate from a previous agreement made between them after she gave birth.
